• With constant pressure control

Impeller
Radial impeller with backward-curved blades, balanced in two planes to quality class G 6.3 according to DIN ISO 1940.

Engine
Outer rotor motor, voltage control, thermostatic switches with external terminals. Single-phase motors up to size 400 have a capacitor integrated into the internal circuit. Models from size 450 use an asynchronous three-phase motor.

Casing
Casing made of weather-resistant AIMg3 aluminum, with a protective grille integrated on the air outlet side.

Assembly
Base made of galvanized sheet steel, deep-drawn air inlet nozzle. For mounting accessories (e.g., roof base), see our wide range of accessories.

Vertical Air Outlet:
Vertical air outlet reduces roof pollution. Furthermore, noise levels are significantly lower than those of horizontal roof fans.

Low Energy Consumption Due to High Efficiency:
The impeller with backward-curved blades offers two important advantages: it provides very high efficiency and is resistant to pollution.
