Fume Extractor and Exhaust Fans

Recommended airflow should be established from the hood, enclosure, ductwork, contaminant, capture requirements, and system resistance rather than selected from a generic figure. IPF Colasit products span applications from smaller laboratory and industrial ventilation systems through high-volume exhaust installations, with listed product capacities ranging from up to 6,000 CFM to 50,000–125,000 CFM. Request product selection guidance for your system.

Available construction options include PVC, polypropylene, spark-resistant PPs-EL, and fiberglass reinforced plastic. Material selection should reflect the chemicals, temperatures, static-control requirements, and operating conditions in the airstream. Polypropylene is positioned for resistance across most of the pH range, while FRP options support applications involving corrosive environments and chemical process ventilation.

Yes. IPF Colasit provides corrosion-resistant thermoplastic and FRP fans for chemical processing, corrosive gas ventilation, air pollution control scrubbers, wastewater treatment, and related applications. Thermoformed PVC and polypropylene constructions keep metal out of the airstream in applicable designs, while FRP models use corrosion-resistant resin construction. The appropriate configuration depends on the process chemistry and operating conditions.

Selected configurations are designed for spark-sensitive or explosive-atmosphere applications. Spark-resistant PPs-EL and graphite-impregnated options are available, and explosion-proof motors are offered for applicable products. Final selection should consider the complete system, including the airstream, motor, controls, installation, and applicable safety requirements. IPF Colasit can help evaluate the required configuration from your process details.

The product range includes direct-drive, belt-drive, axial, centrifugal, in-line, and roof-mounted fan configurations. Direct-drive models mount the impeller on the motor shaft, while belt-drive designs provide a separate drive arrangement. Axial and centrifugal options address different airflow and pressure requirements, and in-line or roof-mounted designs support specific installation layouts. Selection should follow the system design.

Axial fans and centrifugal fans serve different ventilation system requirements. FRP axial fans are available for industrial ventilation, chemical processing, wastewater treatment, and laboratory fume hoods. FRP centrifugal fans are used for similar corrosive applications and can be evaluated where the system requires their impeller and pressure characteristics. Ductwork, static pressure, airflow, chemistry, and mounting arrangement should guide selection.
