VTR in-line fan

The VTR series fan is equipped with a turbine with perpendicular rotor blades. Thanks to its construction, the turbine can create a significantly higher air pressure in the ventilation duct than a fan with a traditional propeller. This allows the transportation of air over long spans. The use of VTR in the ventilation system will eliminate the need to install auxiliary fans. The product can be installed both vertically and horizontally. The fan is available in a double-speed version for better adjustment of the fan capacity to the user’s needs.

Two-speed

Fans marked with this icon are equipped with two-speed motors. They are turned on and off with a switch that is an element of the building’s electrical system (not included in the device), except for the WA100DWP fan, which is equipped with a power cord with plug for a traditional electrical socket (type E 230V AC 50Hz). The fan is started after switching the ON/OFF switch on the power cable. Depending on the model, the motor speed is changed by pulling the cord switch (WA models) or pressing the second button on the wall switch, recommended for connecting the VTR series in-line fans. Then the first button is used to turn the fan on and off.
