Centrifugal Fans

Multiblade Forward Curved (MI)

The multiblade (MI) fan is the most common type used in the heat treating industry. Commonly referred to as “squirrel cage”, our MI fans are usually specified for large volumes of flow against low to medium static pressures. The forward curved blades deliver the same volume of air at reduced RPM as the radial and backward inclined blades. The reduced RPM yields lower stresses in the wheel and allows operation at higher temperature for the same air volume specified. This series of fans has been developed and refined over the lifetime of the company and is suitable for continuous heavy duty applications. Depending on RPM, these fans can operate in temperatures up to 1780 ° F. We offer MI fans in many mounting configurations to meet your installation requirements including housing fans and plug cartridges.

Radial Blades (P)

The radial blade (P) fan is considered to be self-cleaning and should be used in applications where there is a potential for dust to build up on the wheel. Commonly referred to as “paddle wheel”, our type P fans are usually specified for medium volumes of flow against medium to large static pressures. This series of fans has been developed and refined over the lifetime of the company. Their rugged construction and structural integrity make these fans suitable for continuous heavy duty applications. Depending on RPM, these fans can operate in temperatures up to 2200 ° F. We offer the radial blade fan in many mounting configurations to meet your installation requirements including housing fans and plug cartridges.

Backward Inclined (BI)

The backward inclined (BI) fan has wheel blades that are flat and lean away from the direction of the wheel rotation. Type BI fans are usually specified for medium volumes of flow against low to medium static pressures. This type of fan runs at a relatively high speed, however, it is more efficient than the multiblade (MI) or radial blade (P) fans. To move a given amount of air the BI fan is of a non-overloading design and is suitable for systems with fluctuating system resistance. This series of fans has been developed and refined over the lifetime of the company. Their rugged construction and structural integrity make these fans suitable for continuous heavy duty applications. Depending on RPM, these fans can operate in temperatures up to 1150 ° F. We offer the backward incline fan in many mounting configurations to meet your installation requirements including housing fans and plug cartridges. The backward inclined fan is ideal for ovens, furnaces, and ducted applications.
