- the three housing parts can be without mechanical fasteners and without welding in can be connected to one another in an airtight manner.
- the airtight seam connections are useful designed as a standing seam.
- the fan can be easily optimized Fan module in an essentially central opening the strip-like wall directly or by means of a Holding frame can be fixed.
- a pre-assembled, adjusted and calibrated fan module can be in one Quality-controlled series production manufactured and functional be checked before installation.
- For the A radial fan is best suited for the supply air unit.
- the air filter arrangement is preferably at least a surface filter element arranged in a filter frame trained, the filter frame as a load-bearing Element for the housing towards this with an edge circumferential sealing groove is provided for sealing Inclusion of the free edges delimiting the discharge opening of the housing or free edges of one at the blow-out opening arranged intermediate or adapter frame formed is.
- the seal groove contains a sealant, which is preferably a viscous sealant (Fluid seal) is. You have to do that with the Fan-provided housing for mounting only on the Put on the filter frame to create a sealing connection achieve.
- the viscous sealant which is also under Retention of elastic properties can solidify also serves to fix the housing.
- a ceiling profile arrangement of a clean room serves as a holding device for the filter frame a ceiling profile arrangement of a clean room.
- a large number of such air supply units is in regular use Grid arrangement held in the ceiling profile arrangement and at least partially form the ceiling of the clean room.
- these supply air devices are only direct or via Adapter frame on the individual elements of the ceiling profile arrangement put on.
- the fan is expediently on the intake side a pre-filter.
- a silencer arrangement is provided, which in particular as arranged on the fan Silencers, e.g. Hood silencer, is formed.
- the housing can be soundproof and / or have sound-absorbing inner lining.
- a housing 10 consists of two parallel to each other vertical side walls 11, 12 and an upper strip-like jacket wall 13.
- the side walls 11, 12 have an essentially semi-elliptical shape, the longitudinal margins in the middle area in run essentially parallel and the upper long edge at the two end areas arched to the lower one Longitudinal edge runs out.
- the two parallel long edges the strip-like jacket wall 13 are with the upper, in part arch-like longitudinal edges of the two side walls 11, 12 by means of fold connections 14, 15 sealingly connected, in the exemplary embodiment as standing seams are trained.
- hood-like Formed housing 10 which is open at the bottom, the lower longitudinal side edges of the side walls 11, 12 and the two transverse edges of the casing wall 13 a lower one Limit discharge opening.
- the upper wall 13 is thereby according to the shape of the side walls 11, 12 curved.
- the blow-out opening can - as shown - have the shape of an elongated rectangle, however, it can also be square.
- the side walls 11, 12 and the jacket wall 13 are made for example made of galvanized and / or powder-coated or stainless steel sheet or aluminum sheet.
- the upper casing wall 13 has a receiving opening approximately in the middle for a trained as a radial fan Fan 16 on. This sucks in air from above and it blows out radially laterally in the housing 10, like this is represented by arrows in Fig. 1.
- the air flow follows the curvature of the casing wall 13.
- the fan 16 is used as a pre-assembled, adjusted and calibrated fan module into the opening from above used and fixed to the jacket wall 13. Especially when the fan 16 differs from FIG. 1 does not have its own module housing, can be attached a holding frame can also be used, such as this shown and described in EP-A-0 735 329 is.
- the fan 16 has a flat surface on the suction side
- Pre-filter 17 provided and can be used on the output side for sound absorption have a hood muffler 18, the only is shown in dashed lines.
- a hood muffler 18 can be another 16 of the fan Silencers can be placed downstream, in simpler Models also dispense with silencers and pre-filters can be.
- An air filter arrangement 19 has a rectangular shape Filter frame 20 in which a surface filter element 21 is held. Of course, instead of of a surface filter element 21 several individual surface filter elements fill the filter frame 20.
- a viscous sealant 23 (fluid seal) contains.
- the sealant 23 can either remain viscous, or it solidifies into one elastic, rubber-like seal. In both cases thereby holding the housing 10 on the filter frame 20.
- the housing 10 has a sound-absorbing inner lining on the inside 24, that is, a sound absorbing material is on the inside of the side walls 11, 12 and Shell wall 13 applied. It should be noted that this inner lining 24 is not quite up to the extends the lower edges so that they are still in the sealing groove 22 can be used.
- the filter frame 20 has one on its lower edge laterally protruding, ledge-like surrounding projection 25.
- a ceiling profile arrangement 26 used on the ceiling of a clean room.
- This ceiling profile arrangement consists of a variety of at the Ceiling fixed support rods 27, which are in a regular Grids are arranged.
