Description

USE

Supply and extract ventilation systems installed in various premises. Ideal solution for boosting large air volumes at low aerodynamic resistance in the ventilation system.

SPEED CONTROL

Smooth speed control with an external thyristor controller or step speed control with an external auto transformer (both available upon separate order).

MOUNTING

The fan is installed in air ducts by connecting flanges on the fan casing. Power is supplied through an external terminal box.

DESIGN

Compact steel casing and impeller with a special polymer coating. Casing is equipped with connecting flanges for easy mounting into air duct. The fan is equipped with a terminal block for connection to power mains.

MOTOR

Two-, four- or six-pole asynchronous motor with external rotor and axial impeller. Single-phase (E) or three-phase (D) motor modifications. Equipped with ball bearings for longer service life. Integrated thermal protection with automatic restart.
