Description

The PPA is a circular fresh air intake element with a telescopic housing for mounting in an exterior wall near the ceiling structure. It has an internal grille with an integrated control damper that can be operated by a cord. The PPA has a built-in silencer. Telescopic extension allows installation in the wall without the aid of screws. The two parts of the telescopic extension are joined and pulled together through the wall using internal screws. The PPA is supplied with two types of outdoor grille, while type 1 is equipped with an insect screen.

The inlet element is supplied with silencers in two thicknesses. The silencer is lint-free, washable and can be easily removed.

Information

The PPA is supplied with a two-part noise insulation with a diameter of 140/50 mm. If more airflow is required, the inner part of the insulation is removed to increase the internal cross section. This reduces the noise attenuation by 3 dB (see technical data). Short inlet elements for installation in lightweight constructions are available on special order, but these elements have a lower sound attenuation.
