VENTS 125 QUIETLINE-K DUO AXIAL FAN Ø 125 MM / 145 M³ + 197 M³

The Vents 125 Quietline-K DUO achieves a maximum air flow combined with a low noise level to ensure an ideal room microclimate. The fan transports low and medium air flow volumes for small distances at low air resistance in the ventilation system.

Its casing and impeller are made of high quality durable ABS plastic which is UV-resistant. The exhaust spigot is fitted with specially designed air flow rectifiers to reduce air turbulence, noise level and increase air pressure. Thanks to the smart design, the efficiency of the fan is high and the service life is long.

The electric single-phase two speed motor is designed for continuous operation and requires no maintenance. In addition, the motor is equipped with overheating protection which prevents motor overload. You can controll the fan by a room light switch. This switch is not included in the delivery package. Speed control is possible via a thyristor speed controller.

The fan is mounted into a matching duct size and is suitable for air ducts of Ø 125 mm. In case of a flexible duct connection, always secure the fan with clamps for safety. The mounting bracket enables fan installation on both horizontal and vertical flat surfaces.

Do you want to increase performance? Serial mounting of two fans boosts the operation pressure.
