Kice FC Fans are general service fans that provide maximum versatility and reliability. Kice FCW Fans have the same features as the Kice FC Fans but are designed with narrow width blades that can operate at higher speeds and higher static pressures. Kice FCW Fans are designed for negative pressure pneumatic conveying systems.
This customized approach provides customers with highly efficient solutions to their complicated pneumatic conveying needs. Kice FA Fans feature an airfoil sometimes called backward inclined fan wheel that is designed to handle dust free air streams. Typically installed on the clean air side of a baghouse filter, FA Fans are more efficient and quieter that other fan designs. The FA Fan is a non-overloading fan in terms of horsepower. It should only be used in clean air applications. Upon close inspection, one will notice the open structure and lack of cracks and crevices on the base.
Continuous welds are standard on Kice Fans. This design minimizes surface area for dust build-up and allows easy access for cleaning around the fans. Heavy-Duty Construction starts with square tubing bases rather than sheet metal type bases which are commonly used by other fan manufacturers. Continuous welds throughout also add the rigidity of Kice Fans. Centrifugal Fans Value and Longevity With over 50 years in the pneumatic systems business, Kice puts a priority on the engineering and construction of Kice Industrial Fans.
Mesh type openings are provided for viewing and for sanitation purposes.

Fans and Appurtenances. Commercial Ventilators. Instead, you can install this inline fan in your attic, tie up to four locations via a Wye and make your bathroom a quiet place. When closed, they prevent cold air from entering the home in winter, or air-conditioned air from leaving the home in summer. The centrifugal fan displaces a constant volume of air in a given system regardless of air density. When a centrifugal fan is specified for a given CFM and static pressure at conditions other than standard, an air density correction factor must be applied to select the proper size fan to meet the new condition.
The centrifugal fan performance tables provide the fan RPM and power requirements for the given CFM and static pressure at standard air density. When the centrifugal fan performance is not at standard conditions, the performance must be converted to standard conditions before entering the performance tables. Centrifugal fans rated by the Air Movement and Control Association AMCA are tested in laboratories with test setups that simulate installations that are typical for that type of fan.

Usually they are tested and rated as one of four standard installation types as designated in AMCA Standard AMCA Standard defines uniform methods for conducting laboratory tests on housed fans to determine airflow rate, pressure, power and efficiency, at a given speed of rotation. The purpose of AMCA Standard is to define exact procedures and conditions of fan testing so that ratings provided by various manufacturers are on the same basis and may be compared.
For this reason, fans must be rated in standardized SCFM. Centrifugal fans suffer efficiency losses in both stationary and moving parts, increasing the energy input required for a given level of airflow performance. Flow at the intake and its turning from axial to radial direction causes losses at the intake. Friction and flow separation cause impeller blade losses since there is change in incidence angle. Leakage of some air and disturbance in the main flow field is caused due to the clearance provided between the rotating periphery of the impeller and the casing at the entry.
Friction and flow separation also causes losses in the diffuser. Further losses due to incidence occur if the device is working beyond its design conditions. Flow from the impeller or diffuser expands in the volute , which has a larger cross section leading to the formation of eddy , which in turn reduces pressure head.

Friction and flow separation losses also occur due the volute passage. Viscous drag on the back surface of the impeller disc causes disc friction losses. From Wikipedia, the free encyclopedia.
