Abstract

An air filter for an ultra-clean room must fulfill two functions: filtration and recirculation with cooling. These two functions are now combined in a single module divided into two chambers that communicate through a window in the dividing wall. External air is drawn in by the fan (4) at (32) into the recirculation chamber (9) where it mixes with the recirculated air before passing into the filtration chamber (5). Air from the fan is diverted vertically upwards and then downwards into a collection space (25), for equal distribution over the filter (7). The air then passes into the room through slanted slats, away from the oppositely slanted slats of the recirculation chamber in order to avoid short-circuiting of air between the chambers. The recirculation air is drawn in over a cooling heat exchanger (3) under the same fan suction as that drawing in new external lair. The module has inbuilt silencing in the form of isolating layers (17,19,20).

Below the fan 4 there is a filter 7, which in a known manner is formed and through which the clean air flows into the clean room.

Die Filterventilatoreinheit 2 ist durch eine Trennwand 8 von einem den Kühler 3 aufnehmenden Raum 9 getrennt. Die Trennwand 8 ist mit einer Öffnung 10 versehen, die den Aufnahmeraum 9 mit der Zuluftkammer 5 verbindet. The filter fan unit 2 is separated by a partition 8 the cooler 3 receiving space 9 separately. The partition 8 is provided with an opening 10 which the receiving space 9 with the supply air chamber 5 connects.

Der Filter 7 liegt mit geringem Abstand oberhalb eines Zuluftgitters 11, durch welches die Zuluft in den Reinraum eintritt. Der Kühler 3 ist im Bereich oberhalb eines Rückluftgitters 12 vorgesehen, durch das die Rückluft zum Kühler 3 strömt.The filter 7 is located at a short distance above an air intake grille 11 through which the supply air enters the clean room. The cooler 3 is provided in the area above a return air grille 12 through which the return air flows to the cooler 3.

Das Gehäuse 1 ist im dargestellten Ausführungsbeispiel quaderförmig ausgebildet. Es kann selbstverständlich jede andere geeignete Form haben. Vorteilhaft bestehen die Decke 6 und die hieran rechtwinklig anschließenden Seitenwände 13 bis 16 aus Metall. Auf die Innenseite der Decke 6 ist eine Schalldämmschicht 17 aufgebracht.The housing 1 is cuboid in the illustrated embodiment educated. It can of course be any other suitable one To have shape. Advantageously, there are the ceiling 6 and at right angles to it adjoining side walls 13 to 16 made of metal. On the A sound insulation layer 17 is applied to the inside of the ceiling 6.

Der Ventilator 4 ist an einer Platte 18 gehalten, die beispielhaft quadratischen Umriß hat (Fig. 2) und zumindest an zwei einander gegenüberliegenden Seiten eine Schalldämmschicht 19, 20 überragt und an der Gehäuseseitenwand 14 und an der Trennwand 8 befestigt ist. Die Schalldämmschicht 19 ist an der Innenseite der Gehäuseseitenwand 14 und die gegenüberliegende Schalldämmschicht 20 an der Trennwand 8 vorgesehen, die sich vom Gehäuseboden bis zur Gehäusedecke 6 zwischen den einander gegenüberliegenden Gehäusewänden 13, 15 erstreckt. Die Trennwand 8 besteht vorteilhaft aus Metall.The fan 4 is held on a plate 18, which are square, for example Outline has (Fig. 2) and at least on two opposite A soundproofing layer 19, 20 protrudes over and on the housing side wall 14 and is attached to the partition 8. The Soundproofing layer 19 is on the inside of the housing side wall 14 and the opposite soundproofing layer 20 on the partition 8 provided, which extends from the housing base to the housing cover 6 between the opposite housing walls 13, 15 extends. The partition 8 is advantageously made of metal.

Wie Fig. 3 zeigt, ist der Filter 7 von einem Rahmen 21 aufgenommen, dessen Rahmenseiten etwa L-förmigen Querschnitt haben. Auf dem in der Einbaulage unteren Schenkel 22 des Rahmens 21 liegt der Filter 7 auf. Parallel zum nach innen abgewinkelten Rahmenschenkel 22 hat der Rahmen 21 einen oberen Rahmenschenkel 23, dessen freies Ende 24 nach oben abgewinkelt ist und mit dem der Rahmen 21 an der Innenseite der Gehäuseseitenwände 13 bis 15 und an der Trennwand 8 befestigt ist.3 shows, the filter 7 is received by a frame 21, whose frame sides have an approximately L-shaped cross section. On the in the installed position lower leg 22 of the frame 21, the filter 7 on. Parallel to the inwardly angled frame leg 22, the frame 21 has an upper frame leg 23, the free end 24 is angled upwards and with which the frame 21 on the inside of the housing side walls 13 to 15 and on the Partition 8 is attached.

Der Filter 7 liegt mit Abstand unterhalb des Ventilators 4, so daß ein zwischen ihm und dem Filter liegender Strömungsraum 25 gebildet wird. Der Strömungsraum 25 stellt sicher, daß die Reinluft über die gesamte Fläche des Filters 7 gleichmäßig zugeführt wird.The filter 7 is spaced below the fan 4, so that a flow space 25 located between it and the filter becomes. The flow chamber 25 ensures that the clean air over the entire surface of the filter 7 is fed evenly.

An der Unterseite des Ventilators 4 ist eine Umlenkeinrichtung 26 befestigt. Sie wird durch eine ebene Platte 27 gebildet, die allseitig über den Ventilator 4 übersteht und deren äußerer Rand 28 rechtwinklig nach oben verläuft. Die vom Ventilator 4 in noch zu beschreibender Weise angesaugte Reinluft gelangt in den zwischen dem Plattenrand 28 und dem Ventilator 4 gebildeten Ringraum 29, in dem die Reinluft aufwärts strömt. Da der Plattenrand 28 mit Abstand unterhalb der Tragplatte 18 endet, kann die Reinluft aus dem Ringraum 29 austreten und in den zwischen dem Plattenrand 28 und den Schalldämmschichten 19, 20 befindlichen Strömungsraum 30 gelangen. In ihm strömt die Reinluft in den Strömungsraum 25, in welchen der Strömungsraum 30 übergeht. Vom Strömungsraum 25 aus strömt die Reinluft durch den Filter 7 und gelangt über das Zuluftgitter 11 in den darunter befindlichen Reinraum.A deflection device 26 is attached to the underside of the fan 4. It is formed by a flat plate 27, which on all sides protrudes the fan 4 and the outer edge 28 at right angles runs upwards. The fan 4 in to be described Clean air sucked in this way gets into the between the plate edge 28 and the fan 4 formed annular space 29, in which the clean air flows upwards. Since the plate edge 28 at a distance below the Carrier plate 18 ends, the clean air can escape from the annular space 29 and in the between the plate edge 28 and the sound insulation layers 19, 20 located flow space 30 arrive. In him the clean air flows into the flow space 25, in which the flow space 30 passes. The flows from the flow chamber 25 Clean air through the filter 7 and passes through the supply air grille 11 in the clean room underneath.

Die Schalldämmschicht 17 erstreckt sich über die gesamte Innenseite der Gehäusedecke 6, so daß sie auch im Kühleraufnahmeraum 9 vorgesehen ist (Fig. 3). In der Gehäuseseitenwand 16 befindet sich eine Öffnung 31, an die außenseitig ein Zuluftstutzen 32 angeschlossen ist, über den Außenluft 33 zugeführt werden kann. Die Öffnung 31 befindet sich unmittelbar im Anschluß an die deckenseitige Schalldämmschicht 17 und dadurch mit Abstand oberhalb des Kühlers 3. Die Außenluft 33 strömt rechtwinklig zur Rückluft 34 in den Raum 9, in dem die Außenluft 33 mit der Rückluft 34 vermischt wird. Der Raum 9 bildet somit auch eine Mischkammer für die Außenluft und die Rückluft. Aus dem Raum 9 gelangt die Mischluft durch die Öffnung 10 der Trennwand 8 in die Zuluftkammer 5 zwischen der Tragplatte 18 und der deckenseitigen Schalldämmschicht 17. The sound insulation layer 17 extends over the entire inside the housing cover 6 so that it also in the radiator receiving space 9 is provided (Fig. 3). Is located in the housing side wall 16 an opening 31 to which an air inlet connection 32 is connected on the outside is, can be supplied via the outside air 33. The opening 31 is located immediately after the ceiling Soundproofing layer 17 and thereby at a distance above the cooler 3. The outside air 33 flows at right angles to the return air 34 in the Room 9, in which the outside air 33 is mixed with the return air 34. The space 9 thus also forms a mixing chamber for the outside air and the return air. The mixed air passes through the space 9 Opening 10 of the partition 8 in the supply air chamber 5 between the Support plate 18 and the soundproofing layer 17 on the ceiling.

Durch die Gehäusedecke 6 und die Schalldämmschicht 17 sind elektrische Zuleitungen 35 für den Ventilator 4 sowie Zuleitungen 36 für den Kühler 3 geführt.Through the housing cover 6 and the sound insulation layer 17 are electrical Feed lines 35 for the fan 4 and feed lines 36 for led the cooler 3.

Die Trennwand 8 unterteilt das Gehäuse 1 in zwei Aufnahmeräume, von denen der ventilatorseitige Aufnahmeraum größer ist als der kühlerseitige Raum 9.The partition 8 divides the housing 1 into two receiving spaces, of which the fan-side receiving space is larger than the cooler-side Room 9.

Das Zuluftgitter 11 hat über seine Fläche verteilt angeordnete Zuluftöffnungen, an die schräggestellte und parallel zueinander verlaufende Leitbleche 37 anschließen. Sie erstrecken sich vom Öffnungsrand aus schräg in Richtung auf den Aufnahmeraum 9 für den Kühler 3. Dadurch tritt die Zuluft 38 zunächst schräg in den darunter befindlichen Reinraum ein. Aufgrund der Leitbleche 37 strömt die Zuluft 38 vom Raum 9 schräg weg, so daß diese Zuluft nicht sofort wieder über das Rückluftgitter 12 zum Kühler 3 zurückströmt.The supply air grille 11 has supply air openings distributed over its surface, to the inclined and parallel to each other Connect baffles 37. They extend from the opening edge from obliquely in the direction of the receiving space 9 for the cooler 3. As a result, the supply air 38 initially enters the one below it at an angle Clean room. Due to the guide plates 37, the supply air 38 flows from room 9 diagonally away, so that this supply air does not immediately over again the return air grille 12 flows back to the cooler 3.

Auch das Rückluftgitter 12 hat über seine Fläche verteilt angeordnete Öffnungen, an die Leitbleche 39 anschließen. Sie liegen ebenfalls parallel und sind entgegengesetzt zu den Leitblechen 37 des Zuluftgitters 11 geneigt.The return air grille 12 also has distributed over its surface Connect openings to the baffles 39. They are lying too parallel and are opposite to the guide plates 37 of the supply air grille 11 inclined.

Im Einsatz der Reinstlufteinrichtung strömt die gefilterte Zuluft 38 durch das Zuluftgitter 11 unmittelbar in den Reinraum. Anschließend strömt die mit den aufgenommenen Teilchen versehene Rückluft 34 durch das Rückluftgitter 12 zum Kühler 3, den sie durchströmt. Hierbei wird die Rückluft 34 gekühlt. Der Kühler 3 liegt horizontal etwa in Höhe des Filters 7. Die Rückluft 34 strömt im Kühlerraum 9 nach oben und gelangt durch die Öffnung 10 in der Trennwand 8 in die Zuluftkammer 5 oberhalb des Ventilators 4. Gegebenenfalls kann über den Zuluftstutzen 32 Außenluft 33 in den Kühlerraum 9 zugeführt werden, in dem sich die Außenluft 33 mit der gekühlten Rückluft 34 vermischt, In diesem Falle tritt diese Luftmischung durch die Öffnung 10 in die Zuluftkammer 5. In der Zuluftkammer 5 strömt die Rückluft durch eine in der Tragplatte 18 vorgesehene Öffnung 40 (Fig. 1) in den Ventilator 4. Die Tragplatte 18 schließt sowohl den Ringraum 29 als auch den Strömungsraum 30 nach oben gegen die Zuluftkammer 5 ab. Die aus dem Ventilator 4 austretende Luft gelangt in den Ringraum 29, in dem sie durch den aufwärts verlaufenden Plattenrand 28 nach oben umgelenkt wird. Über den den Ringraum 29 umgebenden Strömungsraum 30 strömt die Zuluft dann nach unten in den Strömungsraum 25, der dafür sorgt, daß die Zuluft über die Eintrittsfläche des Filters 7 gleichmäßig verteilt wird. Beim Durchtritt der Zuluft 38 durch den Filter 7 wird die Zuluft in bekannter Weise vor ihrem erneuten Eintritt in den Reinraum gereinigt und gefiltert.When using the ultrapure air device, the filtered supply air 38 flows through the supply air grille 11 directly into the clean room. Subsequently the return air 34 provided with the picked up particles flows through the return air grille 12 to the cooler 3 through which it flows. Here the return air 34 is cooled. The cooler 3 lies approximately horizontally in Height of the filter 7. The return air 34 flows in the cooler 9 above and passes through the opening 10 in the partition 8 into the supply air chamber 5 above the fan 4. If necessary, over the supply air connection 32 outside air 33 is fed into the cooler chamber 9 in which the outside air 33 with the cooled return air 34 mixed, in this case this air mixture passes through the opening 10 into the supply air chamber 5. The return air flows in the supply air chamber 5 through an opening 40 provided in the support plate 18 (FIG. 1) in the fan 4. The support plate 18 closes both the annular space 29 as well as the flow space 30 upwards against the supply air chamber 5 from. The air emerging from the fan 4 enters the annular space 29, in which it runs through the upwardly extending plate edge 28 is diverted upwards. About the surrounding annular space 29 Flow space 30 then flows the supply air down into the flow space 25, which ensures that the supply air over the entry surface the filter 7 is evenly distributed. When the supply air passes 38 through the filter 7, the supply air is in a known manner before its renewed Entry into the clean room cleaned and filtered.

Anstelle des Ringraums 29 können auch nur beiderseits des Ventilators 4 parallel zueinander verlaufende Strömungskanäle vorgesehen sein, die sich zwischen den Gehäuseseitenwänden 13 und 15 erstrecken. In diesem Falle strömt die aus dem Ventilator 4 gelangende Luft über die Plattenränder 28 in den Strömungsraum 30.Instead of the annular space 29, it is also possible to use the fan only on both sides 4 parallel flow channels are provided be between the housing side walls 13 and 15th extend. In this case, the one coming out of the fan 4 flows Air over the plate edges 28 into the flow space 30.

Da bei der Reinstlufteinrichtung der Ventilator 4, der Filter 7 und der Kühler 3 in einem gemeinsamen Gehäuse untergebracht sind, ist ein aufwendiges Kanalsystem zur Zuführung der Rückluft nicht erforderlich. Die Reinstlufteinrichtung ist als Modul ausgebildet, das beispielsweise in eine Öffnung einer Rasterdecke 41 eingesetzt werden kann. In den Fig. 2 und 3 sind die einander rechtwinklig kreuzenden Tragschienen 42 und 43 der Rasterdecke 41 dargestellt. Es ist aber auch möglich, die Module an einer bauseitigen Decke hängend zu befestigen und reinraumseitig an eine abgehängte Decke, beispielsweise aus Modulblechen, anzuschließen.Since in the pure air device the fan 4, the filter 7 and the Radiator 3 are housed in a common housing is a complex duct system for supplying the return air is not required. The pure air device is designed as a module, for example can be inserted into an opening in a grid ceiling 41 can. 2 and 3 are the intersecting at right angles Support rails 42 and 43 of the grid ceiling 41 are shown. But it is it is also possible to hang the modules on an on-site ceiling attach and clean room side to a suspended ceiling, for example made of modular sheets.

The housing 48 is through at the top sections of the side walls angled inwards at right angles and the plate 18d fastened thereon closed. The unit 47 can be pre-assembled and easily in the housing 1d of the pure air device be used.

Das Gehäuse 1d der Reinstlufteinrichtung sitzt auf einem Einbaumrahmen 49, mit dem die Einrichtung, wie anhand der Ausführungsform nach den Fig. 1 bis 3 erläutert, auf der Rasterdecke 41 aufgesetzt oder auch hängend an einer bauseitigen Decke befestigt werden kann.The housing 1d of the pure air device sits on a built-in frame 49, with which the device, as based on the embodiment 1 to 3 explained, placed on the grid ceiling 41 or attached to a ceiling on site can.

Der Zuluftstutzen 32d ist an der Seitenwand 14d des Gehäuse 1d vorgesehen. Dadurch befindet sich der Zuluftstutzen 32d auf der vom Kühler 3d abgewandten Seite der Filter-Ventilator-Einheit 2. Diese Anordnung hat den Vorteil, daß die durch den Kühler 3d strömende und in die Zuluftkammer 5d gelangende Luft sowie die durch den Zuluftstutzen 32d zugeführte Außenluft symmetrisch vom Ventilator 4d aus der Zuluftkammer 5d angesaugt werden.The supply air connection 32d is on the side wall 14d of the housing 1d intended. As a result, the supply air connection 32d is located on that of the Cooler 3d side facing away from the filter fan unit 2. This Arrangement has the advantage that the flowing through the cooler 3d and air entering the supply air chamber 5d and through the supply air nozzle 32d outside air supplied symmetrically from the fan 4d be sucked out of the supply air chamber 5d.

Wie anhand der Fig. 1 bis 3 erläutert worden ist, strömt die Rückluft 34 über den Kühler 3d in den Raum 9d und gelangt über die Öffnung 10d in die Zuluftkammer 5d. Die aus dem Ventilator 4d austretende Luft wird an der Umlenkeinrichtung 26d radial nach außen umgelenkt und strömt über den Strömungsraum 30d in den Strömungsraum 25d und von dort durch den Filter 7d. Der Strömungsraum 25d sorgt dafür, daß die Zuluft über die Eintrittsfläche des Filters 7d gleichmäßig verteilt wird. Beim Durchtritt durch den Filter 7d wird die Zuluft in bekannter Weise vor ihrem Eintritt in den Reinraum gereinigt und gefiltert.As has been explained with reference to FIGS. 1 to 3, the return air flows 34 via the cooler 3d into the room 9d and passes through the opening 10d into the supply air chamber 5d. The exiting from the fan 4d Air is deflected radially outward at the deflection device 26d and flows into the flow space 25d via the flow space 30d and from there through the filter 7d. The flow space 25d ensures that the supply air is uniform over the inlet surface of the filter 7d is distributed. When passing through the filter 7d, the supply air becomes known Way cleaned and filtered before entering the clean room.

An der Seitenwand 16d des Gehäuses 1d befindet sich am oberen Randbereich ein thermostatisches Regelventil 50, mit dem der Kühler 3d geregelt werden kann.On the side wall 16d of the housing 1d is on the top Edge area a thermostatic control valve 50 with which the cooler 3d can be regulated.

Unterhalb des Vorfilters 46 befindet sich im Raum 9d ein Meßstutzen 51, an den über eine Meßleitung 52 ein weiterer Meßstutzen 53 angeschlossen ist, der im Bereich neben dem Ventilator 4d im Strömungsraum 30d angeordnet ist. Über diesen Meßstutzen 53 kann mit einem an den Meßstutzen 51 angeschlossenen Meßsensor der Druck im Strömungsraum 30d gemessen werden. Außerdem kann der Druck unterhalb des Filters 7d mit einem weiteren (nicht dargestellten) Sensor ermittelt werden. Aus der Druckdifferenz lassen sich Rückschlüsse auf die Belastung des Filters 7d ziehen. So läßt sich feststellen, wann der Filter 7d gereinigt und/oder ausgetauscht werden muß. Mit den beiden Meßstutzen 51 und 53 ist es auch möglich, die Partikelkonzentration im Strömungsweg der Luft vor dem Filter 7d zu erfassen. Insbesondere beim Einsatz der Reinstlufteinrichtung im Pharmaziebereich kann somit die Integrität des Schwebstoffilters 7d überprüft und überwacht werden.Below the pre-filter 46 there is a measuring nozzle in the space 9d 51, to which a further measuring connection 53 is connected via a measuring line 52 is in the area next to the fan 4d in the flow space 30d is arranged. About this test socket 53 can with a pressure sensor connected to the measuring nozzle 51 be measured in the flow space 30d. In addition, the pressure below the filter 7d with a further sensor (not shown) be determined. Conclusions can be drawn from the pressure difference pull on the load of the filter 7d. So it can be determined when the filter 7d needs to be cleaned and / or replaced. With the two measuring spouts 51 and 53, it is also possible to determine the particle concentration to detect in the flow path of the air in front of the filter 7d. Especially when using the pure air device in the pharmaceutical sector can thus check the integrity of the particulate filter 7d and be monitored.

Im Bereich unterhalb des Vorfilters 46 befindet sich im Strömungskanal 60 ein Temperaturfühler 54, der auf das thermostatische Regelventil 50 wirkt. Anstelle des thermostatischen Regelventils kann auch ein elektrisches bzw. elektromotorisches Regelventil eingesetzt werden. Zusätzlich kann im Strömungskanal 60 ein weiterer Temperaturfühler eingebaut werden, mit dem die Raumtemperatur erfaßt werden kann. In the area below the pre-filter 46 is located in the flow channel 60 a temperature sensor 54, which on the thermostatic control valve 50 works. Instead of the thermostatic control valve, too an electric or electromotive control valve can be used. In addition, a further temperature sensor can be located in the flow channel 60 be installed with which the room temperature can be detected can.

Die Wand 16d des Gehäuses 1d ist mit einem Stutzen 55 versehen, über den bei Bedarf die gesamte oder ein Teil der Rückluft einer nachgeschalteten (nicht dargestellten) Fortluftanlage zugeführt werden kann.The wall 16d of the housing 1d is provided with a socket 55, over which, if necessary, all or part of the return air downstream (not shown) exhaust air system are supplied can.

Die gefilterte und gekühlte Zuluft 38 tritt allseitig und turbulent in den Reinraum aus. Sie verteilt sich im Reinraum und wird über das Rückluftgitter 12d aus dem Reinraum abgesaugt und über den Wärmetauscher 3d rückgekühlt.The filtered and cooled supply air 38 enters all sides and is turbulent Clean room. It is distributed in the clean room and is via the return air grille 12d suctioned out of the clean room and over the heat exchanger 3d cooled down.

Wie Fig. 8 zeigt, ist das Rückluftgitter 12d auf drei Seiten vom Zuluftgitter 11d umgeben. Das Zuluftgitter 11d hat U-Form und ist mit den Leitblechen versehen, über die die ausströmende Reinstluft in den Reinraum geblasen wird. Die Leitbleche 37d in den einzelnen Bereichen des Zuluftgitters 11d sind so angestellt, daß die Reinstluft in unterschiedlichen Richtungen strömt. In Fig. 8 sind die Ausströmrichtungen der Reinstluft durch Pfeile gekennzeichnet. Die Leitbleche sind entsprechend schräg angestellt, so daß die Zuluft 38 schräg in Richtung auf den jeweils benachbarten Rand des Gehäuses 1d austritt.As shown in FIG. 8, the return air grille 12d is on three sides of the supply air grille 11d surround. The supply air grille 11d has a U-shape and is with the Provide baffles through which the outflowing ultrapure air flows into the Clean room is blown. The baffles 37d in the individual areas of the supply air grille 11d are set so that the pure air in flows in different directions. 8 are the outflow directions the pure air is indicated by arrows. The baffles are accordingly inclined so that the supply air 38 obliquely in Direction emerges on the adjacent edge of the housing 1d.

Wie anhand der Ausführungsform nach den Fig. 1 bis 3 erläutert worden ist, hat auch das Rückluftgitter 12d die schräg liegenden Leitbleche. Diese Leitbleche können, auch bei den vorhergehenden Ausführungsformen, entfallen. Da sich das Rückluftgitter 12d zwischen zwei Abschnitten des Zuluftgitters 11d befindet (Fig. 8), befindet sich innerhalb der Reinstlufteinrichtung im Bereich oberhalb des Rückluftgitters 12d ein Kasten 56, der in Ansicht auf das Rückluftgitter 12d gleiche Umrißform wie dieses Gitter hat. Dieser Kasten 56 hat eine schräg liegende Wand 57, die sich schräg nach unten erstreckt. Die senkrecht zur Zeichenebene gemäß Fig. 7 gemessene Breite dieser Wand 57 entspricht der entsprechenden Breite des Rückluftgitters 12d. An diese Wand 57 sind Seitenwände angeschlossen, die sich senkrecht nach unten erstrecken und längs der Längsränder 58, 59 (Fig. 8) des Rückluftgitters 12d erstrecken. Auf diese Weise ist der Bereich oberhalb des Rückluftgitters 12d strömungstechnisch gegen die benachbarten Bereiche des Zuluftgitters 11d abgetrennt, so daß die über das Rückluftgitter 12d in das Gehäuse 1d eintretende Rückluft sich nicht mit der Zuluft 38 vermischen kann. An der schräg liegenden Wand 57 wird ein Teil oder die gesamte Rückluft zum Vorfilter 46 gelenkt, der den Schwebstoffilter 7d vor einer übermäßigen Verschmutzung schützt.As has been explained with the aid of the embodiment according to FIGS. 1 to 3 the return air grille 12d also has the inclined baffles. These guide plates can, also in the previous embodiments, omitted. Since the return air grille 12d between two Sections of the supply air grille 11d (Fig. 8) is located inside the pure air system in the area above the return air grille 12d is a box 56 which is the same in view of the return air grille 12d Outline shape like this grid has. This box 56 has one sloping wall 57 which extends obliquely downwards. The 7 measured width perpendicular to the plane of the drawing Wall 57 corresponds to the corresponding width of the return air grille 12d. At this wall 57 side walls are connected, which are extend vertically downward and along the longitudinal edges 58, 59 (Fig. 8) of the return air grille 12d extend. In this way it is Area above the return air grille 12d against the flow the adjacent areas of the supply air grille 11d separated so that the return air entering the housing 1d via the return air grille 12d cannot mix with the supply air 38. On the sloping Wall 57 becomes part or all of the return air to the prefilter 46 steered the suspended particle filter 7d from excessive Protects pollution.

Die beschriebenen Reinstlufteinrichtungen sind kleine, modulare Einheiten, die hervorragend auf dem Gebiet der Pharmazie, der Lebensmittel- und der Biotechnik eingesetzt werden können. Die Module stellen autarke Einheiten dar, so daß ein aufwendiges Kanalsystem zur Zuführung der Rückluft nicht notwendig ist.
