NH-Series Exhaust Fan
NH-Series Fan Centrifugal Exhaust Blower
The KCH NH-Series centrifugal type blower includes many features that result in effective corrosion resistance, high volumes, reduced horse power requirements, and low sound levels. These include:
- A backwardly inclined, FRP coated, steel NH fan wheel which is spark tested for integrity. Optional Solid FRP, Stainless Steel, or Hastelloy Wheels are also available.
- Housing that can be fabricated from either PVC, Poly-pro, or FRP.
- An inlet cone that is heat formed for smooth air flow into the wheel.
- An "A" type frame that is manufactured from heavy gauge steel and epoxy coated for corrosion resistance.
More Exhaust Fan Features
In addition, 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.
Powerful Exhaust Fans, Quiet Operation
The NH-Series Fans, with their stable and efficient performance, are also 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 that is too lightly constructed, has abrupt turns, improper fan foundations, lack of proper isolation between fan and ducts, or poor acoustical conditions adversely affect the sound level of the installation.
KCH Fans are also offered in a Direct Drive configuration to eliminate belts and reduce vibrations.
