Constant air volume flow controller suitable for horizontal and vertical ducts
Mechanical operation
Dial control
Steel construction
Easy setpoint adjustment
NOTUS-S is a constant air volume flow controller with a mechanical type of operation. It requires no auxiliary energy or actuation.
NOTUS-S provides easy, dial-operated airflow control with accuracy with a maximum of 10% flow volume deviation.
NOTUS-S is designed for both horizontal and vertical ducts and comes in rectangular sizes up to 600 x 600 mm.
NOTUS-S is a constant air volume flow controller with a mechanical type of operation. It does not require an auxiliary energy source or actuation to operate. It is intended to control the airflow independently of the duct air pressure in the range of 50 Pa to 1000 Pa. The constant air flow value is adjusted by a rotating dial with the range dependent on the size of the product. Adjustments can be made manually or by an electric actuator. Available in different sizes, it can be installed into both horizontal and vertical ducts.
The rectangular body of the NOTUS-S is constructed from galvanised steel sheet with 20mm flange duct connections at each end. The control damper blade is made from aluminium. The control mechanism on the outer surface of the body consists of ABS plastics levers and transmissions, steel springs, and silicone oil-filled rotary shock absorber, all covered by an ABS box.
