Description
Our popular “BPI” range of backward curved fans are available in AC & DC, single & three phase supply. These backward curved fan impellers are able to function with low noise, whilst also able to maintain a low profile in size as the motor is a mounting within the blade using an external rotor motor design. A new development is that these fans are now also available in a high efficiency EC backward curved fan version.
These backward curved centrifugal fans are located in the air stream and are IP44 protection rated, so a “clean” environment is required. These backward curved impellers develop pressure within the envelope of the blade and as such don’t rely on the casing as in the case of forward curved fans. They are a low cost option and can be easily housed. The inlet ring is where the air is drawn through helping to minimise pressure losses and air leakages and then expelled at 90degree to the inlet axis. Because of this they are ideally suited for high pressure applications.
With our market leading range of motors all available from stock in conjunction with our cross reference database we are able to quickly and easily offer a replacement electric motor for many competitor makes, so should you have a forward curved centrifugal blower by any of these: EBM-PAPST, Ecofit, Rosenberg, REMCO, S&P, etc
