Weather cowl (with acoustic insulation) GfK
With the weather cowl made of GfK the filter apparatus is equipped for outside installation.
The weather cowl protects the filter apparatus or fan from effects of the weather like rain, hail or snow.
An additional acoustic insulation can reduce the sound emission as for example the blow-out sound or the regeneration impulse by up to 15 dB.
With the acoustic hood the sound emission of the regeneration impulse is reduced. If a low absorbent rate is enough, also a connection A (cover and connection piece for vacuum operation) can be used.
Please notice that tubings, acoustic property of the environment and the installation site substantially influence the sound emission.
