Systemair NOTUS-R-250-M0 - CAV controller, manual adjustment

NOTUS-R is a constant air flow volume controller with mechanical type of operation (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 product fits into the circular ducts of 80 mm up to 400 mm in diameter. The constant air flow value can be set manually (product type NOTUS…M0) or by an actuator (product type NOTUS…M1). The product is intended for all applications, where a reliable, precise and cost effective air flow control is required. Highlights • Easy, precise air flow adjustment • Good, stable control accuracy • Small straight equalizing duct length in front of device required • Large pressure drop wirking range • High casing tighness, class C acc. to EN 1751 Types of Product • NOTUS-R...M0: Manually operated CAV controller • NOTUS-R...M1: Actuator operated CAV controller • NOTUS-RI...M0: Manually operated CAV controller with acoustic insulation • NOTUS-RI...M1: Actuator operated CAV cont...
