Crossair provides centrifugal fans and blowers are designed and manufactured to be completely corrosion resistant, highly efficient, and feature smooth, quiet operation. These fans are fabricated to the highest quality standards, are rugged, heavy duty, and are designed for high performance under the most severe duty conditions. Each fan is complete with coated steel frame, corrosion resistant housing and wheel, OSHA approved belt and shaft guards, TFEC motor, drives, drain, flanged outlet and clean-out door.
Centrifugal blowers or fans are among the most efficient and versatile pieces of air moving equipment. Industrial clean air centrifugal fans have the ability to handle a variety of air flows relative to static pressure, with some tolerance for dust and moisture. Centrifugal blowers are quiet and reliable and are made to operate in a variety of environments and applications.
The two most common types of centrifugal blowers are pressure blowers and volume blowers and are typically made of fabricated steel, stainless steel or cast aluminum. Pressure blowers are designed to draw or push air at high pressures, while volume blowers are designed to draw or push air in large volumes.
Centrifugal fans come in four standard types, each with its own specific purpose. Radial fans are high-pressure with medium airflow and best for industrial applications where you typically see the accumulation of dust, or in environments where there is gas or moisture in the air. Forward curve are medium pressure, high airflow fans that can be used in both clean air environment and have ventilating and exhaust applications. Backward curve are high-pressure, high-flow, high-efficiency fans. Airfoil are the highest efficiency fans and are best applied in clean air applications.
The environment in which the system operates is a significant consideration when choosing the right fan or blower. Recommended motors for different environments:
