Ventilating ductwork in contemporary large houses becomes so long and elaborated that even a high pressure furnace fan couldn't generate enough static pressure to blow through the whole length of such a duct. The existing low pressure booster duct fans, even though compact enough to be installed in-line in the house ventilation ductwork, still do not provide enough booster pressure / airflow. The usual solution to this problem was installation of two independent furnaces with different air ducts, which is rather expensive option.<br> <br> A new high pressure (up to 1.5" WG) small vaneaxial Series VA fan is an ideal booster fan for prolonged ducts. Unlike inline centrifugal ventilator, that also generates rather high pressure, the air comes out not from a peripheral outlet ring area, but distributes evenly across its outlet opening like in true axial blowers.<br> <br> The other advantages of VA Series vaneaxial ventilators is their intrinsic spark-resistant construction because of all-aluminum construction; quiet operation of true vaneaxial design; lower energy consumption due to efficient wheel design.<br> <br> Eight different sizes from 6" DIA to 10" DIA offer wide performance range for any ventilation duct design. Direct drive design ensures long live, maintenance-free operation. Explosion proof motors are available too, as well as sliding dampers, various mounting options, additional sound isolation.<br> <br> For additional information please refer to http://www.canadianblower.com/blowers/index.html.<br> <br> Oleg Tchetchel, Ph.D<br> Canadian Blower<br> http://www.canadianblower.com<br> http://www.canadianblower.com/fans/index.html http://www.canadianblower.com/blower/vaneaxial.xml Tue, 24 Oct 2006 16:03:21 -0400
