The BNB series is a backward curved plenum fan.

The full range of BNB series is AMCA certified to Air, Sound and FEG.

Plenum fans are designed for air handling application where the fan wheel operates without a housing. It operates inside a plenum. This results in saving of space normally occupied by the fan housing, transition and diffusers. The fan wheel pressurizes the entire plenum in which the fan is installed. The allows air ducts to be directly connected from any direction of the plenum. The compact size of the plenum fan makes it an excellent selection for retrofit and replacement application and for variable air volume systems.

There are three types of the BNB series, i.e. BNB-R (regular type), BNB-P (high pressure type), and BNB-Q (high volume ratio type).

The operating limit of BNC series is set according to the requirement of Class 1, 11 and 111 limit as defined in AMCA standard 99-16. The BNC series is available in Direct Driven and Belt Driven.
