12-Inch Inline Duct Fans

Size an inline duct fan by establishing the required airflow, duct diameter, duct length, fittings, discharge arrangement, and total static pressure. Then compare the system duty point with the fan performance data. For chemical or corrosive exhaust, also evaluate the gas stream, temperature, construction material, and whether spark-resistant PPs-EL or an explosion-proof motor option is appropriate.

These fans are intended for industrial ventilation, chemical processing, dust collection, corrosive environment applications, and spark-sensitive or explosive-atmosphere facilities. Product information identifies in-line, roof-mounted, and horizontal in-duct installation options. Final suitability depends on the exhaust chemistry, temperature, airflow, pressure, and site-specific safety requirements.

The listed thermoplastic fan solutions use polypropylene, spark-resistant PPs-EL, and PVC depending on the product configuration. Polypropylene is described as chemically inert across most of the pH range and resistant to acid and caustic attack through the full wall thickness. Material selection should be matched to the chemical gas stream and operating conditions.

Yes. The CRDV product is identified for vertical in-line or roof-mounted configurations, with horizontal in-duct mounting also available. Roof covers and flex connectors are listed as available accessories. Installation should account for support, weather exposure, duct alignment, access for maintenance, and the fan’s required airflow and static-pressure duty.

Yes. Spark-resistant PPs-EL material is listed for the CRDV fans and PVC and polypropylene blowers. The blower information also identifies explosion-proof motors as optional. Facilities handling spark-sensitive or potentially explosive atmospheres should have the complete fan, motor, electrical, and installation arrangement reviewed against their applicable safety requirements.

The PVC and polypropylene blower range identifies direct-drive, belt-drive, and in-line or roof-mounted options. Selection depends on the required airflow, static pressure, installation arrangement, maintenance preferences, and system layout. Belt-drive configurations may suit particular access or operating requirements, while in-line models support vertical, roof-mounted, or horizontal duct installation.
