Supply and extract ventilation systems installed in small premises.High-pressure inline fan for ventilation systems installed in multi-level buildings and premises.Mounting in limited space.For multiport extract ventilation from several premises.Compatible with Ø 80 up to 200 mm round air ducts.


Steel supercompact casing covered with special polymer coating.Minimum casing height is only 90 mm.Aerodynamically shaped casing.External terminal block for power supply.Swivel cover provides easy access to the motor.Various casing modifications include from 1 to 6 inlet spigots.The connection spigots are equipped with rubber seals.


Single-phase three-speed external rotor motor with a centrifugal impeller made of galvanized steel.Impeller with forward curved blades for high pressure in the ductwork system.Turbine is designed to maintain permanent air flow irrespective of air resistance fluctuations in the ductworks.Equipped with ball bearings for longer service life.Integrated thermal protection with automatic restart.Dynamically balanced turbine.


Automatic fan speed control as a function of air resistance in the ductwork system provides permanent air flow rate.Three-button speed switch provides manual speed control. Available upon order.Smooth or step speed control with a thyristor or autotransformer speed controller (available upon order) connected to the maximum speed terminal of the motor.


Due to compact design the fan is the ideal solution for mounting in limited spaces, including the space behind false ceiling.Any mounting position.Wall or ceiling mounting with a fixing bracket supplied as a standard.Flexible air ducts are fixed on the fan spigots with clamps.
