Axial duct fan Vents Quietline 125 is designed for use in a supply or exhaust ventilation system. The fan is a duct fan, that is, it is built directly into a network of air ducts or plastic channels. This series of fans has a reduced noise level and low energy consumption, which allows them to be installed directly in the rooms served by ventilation.
Design features
Thanks to the company's own development 'Vents' managed to significantly reduce the noise level. Aerodynamic performance was achieved through a reasonable combination of the shape of the impeller and the rotation speed of the fan motor. The impeller in the fan is mounted on the electric motor shaft.
The fan housing and impeller are made of high-quality plastic, resistant to ultraviolet radiation. The fan uses a single-phase motor in a single-speed design. Built-in protection is used to protect against engine overheating.

Scheme for connecting the fan to the network
Control
Manual
- any switch single-key type, installed in a distribution box. The connection occurs in exactly the same way as a household lighting switch (purchased separately).
- If it is necessary to continuously regulate the speed, you can use a thyristor regulator RS-1-300, connecting it to the maximum speed terminal engine. Reducing productivity also leads to a decrease in noise levels, which is very important when ventilating domestic premises at night. The regulator is not included in the delivery package.
Automatic control unit
- Using an electronic control unit BU-1- 60(See Electrical Accessories). The control unit is supplied separately.
How to install the fan
- The fan is connected to an air duct with a diameter of 125 mm. If the duct diameter is smaller or larger, use a reducer or connector. When installed with flexible air ducts, the fan is attached using clamps to the wall or ceiling.
- The fan can be installed in a horizontal or vertical position. When installed vertically, it is necessary to provide protection from condensation or precipitation.
- The fan is intended for indoor installation only, outdoor installation is not allowed.
