Ventilation Cabinet
The FH with G4 Filter line was developed for air supply systems requiring high airflow and pressure in compact, quiet-operating equipment. Designed for ventilation applications, it features a direct-drive centrifugal fan, eliminating the need for pulleys and belts.
Its robust galvanized steel construction provides enhanced durability. The internal electrical box with side access makes installation and maintenance easier, while the design allows for vertical or horizontal installation. The units are equipped with a thermal protector and operate at temperatures ranging from -40 °C to 65 °C.
Airflow and pressure data account for the pressure drop across G4 filters at half their service life.
