Centrifugal Fans and Blowers
NH-Series (High Volume, Low Pressure)
The KCH AMCA Rated NH-Series Centrifugal Type Blower includes many features that result in effective corrosion resistance, high volumes up to 70,000 CFM, 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
Materials are PVC, PP, FRP, POLYSTRONG® or POLYLAST®
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 powder coated for corrosion resistance

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.
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 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.
CI-Series (Low Volume, Medium Pressure)
The KCH AMCA Rated CI-Series is suitable for continuous operation from 200 to 4200 CFM at up to 18 inches of static pressure. Each Blower is equipped with an FRP coated paddle wheel type impeller which is spark tested for integrity. The housing material can be PVC, polypropylene, Polystrong, Polylast, or stainless steel. The frame is powder coated heavy duty steel.
CI-Series Fans are often used as Push Air Blowers to assist in the Exhaust Hood capture of fumes.
Direct-Drive Exhaust Fan Advantages
POLYSTRONG®, POLYLAST®, PVC, FRP, or polypropylene construction
Excellent performance
No belts to maintain or replace
No pulley costs
Extended bearing life
Extended motor life
Quieter, less vibration in operation
VFD Advantages
Adjustable Air Flow Control
Based on the odor compound and removal efficiency desired, KCH can provide a complete Odor Control System capable of removing up to 99% or more of the nuisance odors. Chemical Scrubbers, Biotrickling Filters, or Carbon Adsorbers are the three main technologies KCH can apply to control the odors.
Fans are equipped with:
Belt drive
Drain
OSHA approved belt guards
TEFC motor
Inlet cone
Direct-Drive Arrangements
Direct-drive Industrial Exhaust Fans and Blowers for industrial fume exhaust stream applications eliminate belts and pulleys, offering superior ease of use at reduced operational costs. Since they do not require belts or pulleys to operate, Direct-drive Fans and Exhaust Blowers circulate polluted airstreams with reduced maintenance costs.
They are designed to be controlled by variable frequency drives (VFDs) which allow operators to adjust rpm and air flow through the system.
