Square-shaped wall vent designed to provide a continuous airflow into the building/house. The vent is supplied with filter and condensation protection. The vent is capable of providing the room with large quantities of fresh air without causing draught.
The soundreduced vent has another wall pipe than the standard vent. Besides the dB-pipe the
vent also contain two cover plates (#165). The pipe length is 400mm as standard but can easily be cut to requested length (max 1200mm).
F90dB has a unique distribution pattern. The vent is airtight underneath the front cover while the top part allows much more airflow than the sides. This unique construction reduces the risk of draught considerably. The internal part contain condensation protection and an easily removed standard filter (dust/insect). Pollen filter and Environmental filter are available as accessories.
The airflow is adjusted by the built-in regulator underneath the vent. The damper plate has pre-pressed punch-outs so that different minimum airflowlevels can be achieved.
A high placing is recommended, preferably above a radiator. With this solution the incoming air get mixed with the convection flow of warm air ensuring maximum comfort. The Fresh 90-serie can with advantage be used in rooms with underfloor-heating due to the unique construction of the air openings.
