The BCD and FCD centrifugal fans with forward/reverse blades are developed with modern technology.
They are designed to meet BS and ISO standards for air, acoustic and performance equivalent to BS,
AMCA and DIN standards. With advanced design for the advantage of fan: forward impeller, wide range of
applications, compact design, high efficiency, cost saving, high operating quality, low noise and quiet
running as well as low power consumption. These fans are ideal for use in central air conditioning systems,
in purifiers. The efficiency of all fans is guaranteed through specific volumetric figures at maximum
differential pressure. Excellent performance and minimal noise are the characteristics of this new series of
