Systemair NOTUS-SI-200x200-M1 - CAV controller, rectangular, insulated, actuator adjustment

NOTUS-S is a constant air volume flow controller with mechanical type of operation (no need for auxiliary energy or actuation). It 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 adjusted by a rotating dial within a range dependent on the size of product manually (type M0) or by an electric actuator (type M1). Design NOTUS-S has rectangular shaped body made from galvanized steel sheet with 20mm flange duct connections at the ends. The control damper blade material is aluminium. The control mechanism on the outer surface of the body consists of ABS plastics levers and transmissions, steel springs, silicone oil filled rotary shock absorber, all covered by ABS box. A version with acoustic insulation (NOTUS-SI…) has 1,9 cm polymer foam layer around the casing, covered by galvanized sheet mantle. The casing of NOTUS-S in all types has leakage class C according to EN 1751 (the damper blade is not intended for...
