CNB 710 – R (RPM 1450) RD 0 25HP
Centrifugal fans type CNA and CNB are light-weight, compact low pressure fans with high efficiency designed for universal installation. They are therefore well suited for commercial ventilation and air conditioning, besides which they are often used in other ventilation plants (industrial and marine) where economic operation and a low sound level are important factors.
Type CNA is available in nine standard sizes with impeller diameters from 250 mm to 1000 mm, and type CNB in seven sizes with impeller diameters from 400 mm to 1000 mm. As appears from the performance curves type CNB is designed for higher speeds than type CNA.
