High Temperature Inline Duct Fans

The CRDV In-Line / Roof Mounted Plastic Fans and PVC and Polypropylene Blowers are listed with airflow capabilities up to 125,000 cubic feet per minute and static pressure handling up to 24 inches. The appropriate selection depends on system resistance, air chemistry, temperature, installation orientation, drive arrangement, and whether spark-resistant construction or an optional explosion-proof motor is required.

Available construction materials include PVC, polypropylene, and spark-resistant PPs-EL. These thermoplastic options are intended for corrosive gas streams and industrial ventilation applications. Polypropylene is described as chemically inert across most of the pH range, while the selected material should be matched to the process chemistry, operating temperature, airflow requirements, and any spark-sensitive or explosive-atmosphere considerations.

These fans are used for industrial ventilation, chemical processing, dust collection, corrosive environment applications, chemical and corrosive gas ventilation, industrial exhaust, and fume extraction. Product information also identifies roof-mounted and horizontal in-duct installation, along with spark-critical and explosion-prone environments. System design should account for the process gas, static pressure, airflow, temperature, and installation configuration.

Yes. The CRDV product information identifies vertical in-line, roof-mounted, and horizontal in-duct mounting capabilities. PVC and polypropylene blower configurations also include roof-mounted and horizontal in-duct installation applications. The mounting arrangement should be selected with the required airflow, static pressure, duct layout, support hardware, roof cover, and flex connector requirements in mind.

Spark-resistant PPs-EL material is available for applications identified as spark-sensitive or explosive-atmosphere environments. The PVC and polypropylene blower information also states that explosion-proof motors are optional. Selection should consider the classified environment, process gas, required airflow, static pressure, motor arrangement, and applicable project specifications before equipment is ordered.

Start with the required airflow and system static pressure, then evaluate gas chemistry, operating temperature, dust or fume loading, installation orientation, and drive preference. Material selection may include PVC, polypropylene, or spark-resistant PPs-EL. Direct-drive, belt-drive, and in-line or roof-mounted configurations are listed, with support options such as stainless steel hardware, roof covers, and flex connectors available.
