Tube Axial Direct Drive Shop All Now
Browse our selection of tube axial direct drive explosion proof inline duct fans built for hazardous environments where flammable gases, vapors, or dust are present. These fans are commonly installed in oil and gas refineries, chemical plants, and other classified locations where reliable air movement is critical for safety. A direct drive motor eliminates belts and pulleys, which means lower maintenance requirements, a more compact profile for tighter duct spaces, and a lower upfront cost compared to belt driven alternatives. Also known as hazardous location, intrinsically safe, or ATEX rated fans, every model in this collection meets strict safety classifications for explosive atmospheres. Browse our selection to find the right match for your application, or contact our team for expert help with sizing and specifications.

Tube Axial Belt Drive Shop All Now
Tube axial belt drive explosion-proof in-line duct fans are engineered to deliver powerful airflow in hazardous environments where flammable gases or vapors are present, such as oil refineries, chemical plants, and paint facilities. Their belt drive design positions the motor outside the airstream, significantly reducing ignition risk while maintaining strong air movement through ductwork. Also known as hazardous location, intrinsically safe, or ATEX-rated fans, these units are essential for code-compliant ventilation in explosive atmospheres. Industrial Fans Direct offers a complete selection of Class I/II Division 1 & 2 certified fans, backed by over 20 years of technical expertise and trusted by facility managers and safety professionals for reliable, compliant ventilation solutions.

Tube Axial Wet Environment Shop All Now
Tube axial wet environment explosion-proof in-line duct fans are designed to provide air movement in hazardous environments where there is a risk of explosion, as well as in wet or damp environments typically encountered during cleaning. These fans are used in industrial settings, such as chemical plants, pharmaceutical facilities, and other hazardous environments where flammable gases or vapors may be present, as well as in areas with high humidity or moisture. These fans are designed with a sealed motor and electrical components to operate in hazardous and high moisture locations. Also know as hazardous location, intrinsically safe, or ATEX rated fans.

Square Duct In-Line Shop All Now
Industrial Fans Direct carries explosion proof centrifugal square inline fans built for hazardous environments where flammable gases, vapors, or dust are present. Their compact, square-profile housing fits directly into square duct runs without adapters, making them ideal for tightly designed ductwork layouts where space is limited. A centrifugal impeller handles high static pressure loads, delivering powerful and consistent airflow even through complex systems. Easy-access panels simplify routine maintenance and reduce downtime. Also known as hazardous location, intrinsically safe, or ATEX rated fans, every model in this collection meets strict safety classifications for classified atmospheres. Browse our selection to find the right fit for your application, or reach out to our team for expert sizing and specification guidance.
How Do I Size the Right Explosion-Proof Inline Duct Fan for My Facility?
Selecting the correct explosion proof inline duct fan starts with understanding your environment's hazard classification. Facilities are rated by the National Electrical Code (NEC) into Class, Division, and Group designations based on the type of hazardous material present. A Class I, Division 1 location with flammable gases requires a different motor and housing rating than a Class II, Division 2 space with combustible dust. Matching the fan's certification to your facility's classification is non-negotiable for both safety and regulatory compliance.
Beyond the hazard rating, you'll need to determine the correct CFM (Cubic Feet per Minute) output for your duct system. Factors like duct diameter, static pressure, run length, and the number of bends in the ductwork all affect how much airflow you actually get at the point of exhaust. Use our CFM calculator to estimate your requirements, or try our Fan Finder tool to narrow down models based on your specifications. Both resources help you avoid undersizing the fan or paying more than necessary for capacity you won't use.
What Safety and Compliance Standards Apply to Explosion Proof Inline Duct Fans?
Explosion proof inline duct fans must meet strict construction and testing standards before they can be installed in classified hazardous locations. UL (Underwriters Laboratories) and AMCA (Air Movement and Control Association) certifications are the most widely recognized benchmarks. A UL-listed explosion proof fan has been tested to contain any internal ignition without allowing flames or sparks to escape the housing, which prevents the surrounding atmosphere from igniting.
OSHA and local fire codes typically mandate that ventilation equipment in hazardous areas carry the appropriate Class and Division ratings for the specific materials on site. Installing a fan without the correct certification can result in code violations, failed inspections, and significant liability exposure. Every explosion proof inline duct fan in our catalog includes clearly listed certifications, so you can verify compliance before placing your order.
What Should You Expect for Installation and Long-Term Performance?
Inline duct fans are designed to integrate directly into round, square or rectangular ductwork, which simplifies installation compared to roof-mounted or wall-mounted alternatives. Most units can be positioned at any point along a duct run, giving you flexibility in placement without major modifications to your existing system. Mounting brackets and hardware are typically included, and many models support both horizontal and vertical orientation.
From a maintenance standpoint, explosion proof inline duct fans with direct-drive motors require less upkeep than belt-driven models because there are no belts to replace or tension to adjust. Sealed, permanently lubricated bearings further reduce service intervals. When you do need replacement parts or technical support, contact our team to identify the correct components and get your system back up and running with minimal downtime.
