Belt Drive Exhaust Fans

Belt drive exhaust fans are used for industrial ventilation, chemical processing, corrosive gas extraction, and fume removal. IPF Colasit products are designed for applications requiring corrosion-resistant thermoplastic construction and, where specified, a metal-free airstream. They can also support long-life, low-maintenance ventilation operations and installations using accessories such as flex connectors, flanges, reducers, and vibration isolators.

The listed belt drive fans are available in PVC, polypropylene, and spark-resistant PPs-EL construction. Material selection should reflect the chemical composition, temperature, and operating conditions of the airstream. Polypropylene is described by IPF as chemically inert across most of the pH range, while PVC and other available materials address different chemistry and application requirements.

CMV Belt Drive Plastic Fans are listed for airflow up to 6,000 CFM and maximum static pressure of 10 inches. Actual selection depends on the required airflow, system resistance, rotation, installation arrangement, and airstream conditions. IPF Colasit can review the application requirements and help identify a suitable configuration and available accessories.

Explosion-proof and spark-proof options are listed for the CMV Belt Drive Plastic Fans. Spark-resistant PPs-EL construction is also available. These options are intended for applications involving spark-sensitive or potentially explosive atmospheres, but the complete fan, motor, controls, and installation should be reviewed against the facility’s hazard classification and engineering requirements before specification.

A belt drive fan uses a belt and pulley arrangement between the motor and fan shaft, while a direct drive fan connects the motor directly to the impeller or shaft. The product information identifies both drive options within the IPF Colasit range. Choosing between them requires consideration of airflow, static pressure, speed control, maintenance access, installation constraints, and the operating environment.

PVC and polypropylene blowers are listed for chemical and corrosive gas ventilation, industrial exhaust and fume extraction, roof-mounted and horizontal in-duct installation, and spark-critical or explosion-prone environments. They offer direct-drive, belt-drive, and in-line or roof-mounted configurations. Selection should account for the required airflow, static pressure, material compatibility, mounting arrangement, and any optional explosion-proof motor requirements.
