High-Velocity Exhaust Fans and Blowers

IPF Colasit offers direct-drive, belt-drive, centrifugal, axial, in-line, and roof-mounted plastic fans and blowers. Direct-drive units mount the impeller on the motor shaft, while belt-drive designs separate the motor from the airstream. Axial and centrifugal arrangements address different airflow and pressure requirements, and in-line or roof-mounted models support specialised installation layouts.

Yes. The range includes thermoformed PVC and polypropylene construction, as well as FRP designs for chemistries and temperatures outside polypropylene’s range. These materials are intended for corrosive gas streams and industrial ventilation. Final material selection should consider the specific chemicals, concentration, temperature, airflow, and static pressure in the application.

Selected models are available with spark-resistant PPs-EL construction, spark-proof features, graphite impregnation, and explosion-proof motor options. These options are intended for spark-sensitive or explosive-atmosphere applications. The complete system should be reviewed against the facility’s hazard classification and engineering requirements before specifying a fan or blower.

Capacity varies by product and configuration. The range includes smaller direct-drive and belt-drive plastic fans rated from 50 to 6,000 CFM, while the CRDV in-line and roof-mounted models can move up to 125,000 CFM. FRP axial and centrifugal fans cover the 6,000 to 50,000 CFM range. Static-pressure capability also varies by model.

Available construction materials include PVC, polypropylene, spark-resistant PPs-EL, and fiberglass-reinforced plastic. Several designs keep metal out of the airstream, while stainless steel is used for selected support sets, motor mounts, and mounting hardware. Material selection should be matched to the chemical and thermal conditions of the application.

The products are designed for low-maintenance industrial operation. Direct-drive models avoid belt maintenance, while belt-drive models use bearings rated for 100,000 hours without greasing. Accessories such as vibration isolators, flexible connectors, flanges, reducers, and roof covers can support installation and system service requirements. Maintenance practices should follow the selected model’s documentation.
