The BNC series is a backward curved
plenum fan.
The full range of BNC 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 BNC series,
i.e. BNC-R (regular type), BNC-P (high pressure type), and BNC-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.

Wheel
The wheel of BNC series have
backward curved blades manufactured in mild steel with polyester powder coating
finish.
Shaft
Shafts are manufactured from
C45 carbon steel. All dimensional tolerances of the shaft are fully checked to
ensure precision fit. All shafts are coated with an anti-corrosion varnish
after assembly.
Bearings
Bearings used are either
deep groove ball bearing type with an adaptor sleeve or spherical roller
bearings type sealed at both sides for different duty application.
Balancing Quality

and dynamically balanced to ISO 1940 and AMCA 204-G2.5 standard.
• All fans after assembly are
trim balanced to ISO 1940 and AMCA 204-G2.5 standard.
• Standard lower than G2.5 is
available upon request.
