NH-SERIES FAN CENTRIFUGAL EXHAUST BLOWER

The KCH NH-Series centrifugal type blower includes many features resulting in effective corrosion resistance, high volumes, reduced horse power requirements and low sound levels. The NH fan wheel is a backwardly inclined FRP coated steel wheel which is spark tested for integrity. The housing can be fabricated from either PVC, Poly-pro, or FRP. The inlet cone is heat formed for smooth air flow into the wheel. The "A" type frame is manufactured from heavy duty steel and epoxy coated for corrosion resistance. Each fan is supplied with belt drive, TEFC motor, drain, shaft seal, outlet flange, and OSHA approved belt and shaft guards. The inlet is complete with either a flanged or flexible connector. The NH fan provides a stable efficiency through a broad range of operation resulting in lower operating costs to the customer throughout the life of the equipment.

The NH-Series Fans, with their stable and efficient performance, are quiet in operation. In fact, quietness is one of the principal features of the Type NH design.

It should be emphasized that maximum quietness in actual operation depends on not only the choice of the fan itself, but also the system of which the fan is a part. Poorly designed ductwork of too light construction or with abrupt turns, as well as improper fan foundations, lack of proper isolation between fan and ducts, and poor acoustical conditions adversely affect the sound level of the installation.
