Inline Air Duct Fans

The best inline fan depends on the air stream, required airflow, static pressure, installation arrangement, and environmental hazards. IPF Colasit offers thermoplastic and FRP options for industrial ventilation, chemical processing, corrosive environments, dust collection, and spark-sensitive facilities. Material selection is especially important where acids, caustics, corrosive gases, or static discharge may affect equipment performance.

Available constructions include polypropylene, spark-resistant PPs-EL, PVC, and FRP. Polypropylene is chemically inert across most of the pH range, while PVC and FRP can address chemistries and temperatures outside polypropylene’s range. Spark-resistant options and graphite impregnation are available for applications requiring static dissipation or spark-sensitive operation. Final selection should reflect the specific air stream.

IPF Colasit products support vertical in-line, roof-mounted, horizontal in-duct, duct-mount, and roof-mount arrangements, depending on the product family. CRDV fans are designed for vertical in-line or roof-mounted configurations and can support horizontal in-duct mounting. Roof covers and flex connectors are also available for applicable installations and system layouts.

Yes. The product range is intended for chemical and corrosive gas ventilation, chemical processing, fume extraction, wastewater treatment, and other harsh air streams. Thermoplastic and FRP constructions resist corrosion without depending solely on a surface coating. The correct material, motor arrangement, and fan design should be selected according to the chemistry, temperature, airflow, and pressure requirements.

Certain configurations are available for spark-sensitive or explosive-atmosphere applications. CRDV fans can use spark-resistant PPs-EL material, while applicable FRP and blower options include spark-resistant or sparkless designs and explosion-proof motor options. These features do not replace project-specific hazard analysis. Consult IPF Colasit to match the fan, materials, motor, and installation to the facility requirements.

Selection should consider required airflow, static pressure, duct arrangement, air-stream chemistry, temperature, solids or dust, motor requirements, and whether the environment is spark-sensitive. IPF Colasit product families offer different materials, drive types, and mounting configurations. Providing system specifications and application details allows the team to recommend a suitable fan configuration and discuss pricing.
