Cost-effective
The NOTUS-R controller provides high levels of reliability and precision while being cost-effective for a range of different applications.
Steel construction
The product is made from galvanised sheet steel with rubber gasket sealed duct connections making it strong and durable.
NOTUS-R is a constant airflow volume controller that’s designed to fit into circular ducts of 80 mm up to 400 mm in diameter. It has a mechanical type of operation which means there is no need for auxiliary energy. The product is intended to control the constant air flow independently of the duct air pressure in the range of 50 Pa to 1000 Pa. The constant air flow value can be set manually or by an actuator. It provides precise and reliable air control in any application where it is required. A small straight equalising duct length in front of the device is required.
Available in different sizes, the NOTUS-R is made from galvanised steel sheet with rubber gasket sealed duct connections. The control damper has a tough but lightweight aluminium construction. The control mechanism is made from ABS plastics levers and transmissions, steel springs, a rotary shock absorber filled with silicone oil and an ABS box.
