NOTUS-S

NOTUS-S is a constant air volume flow controller with mechanical operation (no need for auxiliary energy or actuation). 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 product is installed into rectangular ducts. 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 and M2). The product is ideal for all applications, where a reliable, precise and cost effective air flow control is required.

NOTUS-S is manufactured from galvanized steel sheet with 20 mm 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 plastic levers and transmissions, steel springs, silicone-oil-filled rotary shock absorber, all covered by a ABS box. A version with acoustic insulation (NOTUS-SI…) has a 1,9 cm polymer foam layer around the casing, covered by a 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 the shut-off function so the blade leakage is not classified). The types M1 and M2 are delivered with a pre-installed flow adjustment actuator. On type M0 (with manual adjustment) the actuator kit can be installed additionally. Types M1 and M2 are available only in sizes with height smaller than 500 mm (single control mechanism).
