Definitions
- the invention relates to a ventilation device with sound and Acoustic encapsulation, especially for one in buildings with central or decentralized Ventilation provided ventilation device on the building side.
- Ventilation devices used for ventilation of rooms in a building usually include at least one or more fans.
- the blowers at which are radial blowers, axial blowers or tangential blowers can, are usually embedded in made of sheet metal or in die-cast housing. These blower housings are used to reduce the noise level emanating from the blower inserted in foamed damping material. With foamed damping materials a reduction in the noise level emanating from the fan can be achieved, however, the damper materials most commonly used today are acoustic open damping materials.
- the object of the present invention is to overcome the disadvantages of the state of the art Remedy technology and provide a ventilation device that is in terms of this outgoing noise level and its heat loss is optimized.
- the complete proposed according to the invention Encapsulation of a blower, which is accommodated within a ventilation device, the noise level emanating from the ventilation device can be significantly reduced.

- the sound capsule designed according to the invention also makes it possible to the two blow-out openings provided on the sides of the sound capsule to close a plug element and one separating the two blow-out channels To remove the center bar, so that the air blown out by the blower over this from the the split surrounding sound capsule is able to flow out.
- the variability of the release or closing of different, in the Acoustic capsule designed blowout openings through plug elements can be a very easy adaptation of the sound capsule to the respective application requirements, in particular can be achieved with regard to the ducting in a ventilation unit.
- a filter frame On one side of the sound capsule enclosing the fan, preferably on that Intake opening contained side of the sound capsule of the blower, can be a filter frame be provided.
- the filter frame can either be placed on the intake opening plug on the side of the split sound capsule, or with it Glue the top side.
- the filter frame has an open side and is as Insert filter frame.
- the U-shaped filter frame includes Insertion rails that are between rails formed on the top of the sound capsule are led.
- the insert rails which can be designed as profile rails, have a Guide surface on which the insert filter element to be inserted into the filter frame is drawer-like.
- the connector between the one on the shared Acoustic filter frame can also be inserted through a rib / recess or tongue and groove arrangement, so that the sound capsule enclosed blower only sucks in filtered air passing through the filter element.
- the filter frame can be opened by 90 °, Twisted 180 ° or 270 ° or 360 ° or at any angle at the Suction opening of the blower-side of the split sound capsule mounted become.
