How Do I Size the Right Explosion-Proof Fan for My Duct System?
Proper sizing starts with calculating your required CFM based on air changes per hour for your hazardous location classification. For Class I Division 1 areas with continuous vapor presence, you'll typically need 20-30 air changes per hour, while Division 2 intermittent exposure areas may require 10-20 changes. You can view all classifications here. Beyond CFM requirements, consider static pressure losses through your ductwork—longer runs with multiple elbows demand higher-pressure fans. Our belt drive models excel in high-static applications, delivering consistent performance. Match your fan's motor enclosure type (TEFC or explosion-proof) to your specific hazardous classification, and always verify the temperature rating exceeds your maximum ambient conditions by at least 20°C.
What Maintenance Access Do Belt Drive Models Require?
Belt drive explosion-proof fans require periodic belt tension checks and replacements, but this design actually simplifies maintenance compared to direct drive alternatives. The motor sits outside the airstream, allowing technicians to service belts, bearings, and motor components without entering confined spaces or shutting down entire ventilation systems. Plan for 24-36 inches of clearance around the belt guard for safe access. Most facilities schedule quarterly belt inspections and annual bearing lubrication, with belt replacement typically needed every 18-24 months depending on runtime. The external motor placement also means cooler operating temperatures, extending bearing life and reducing emergency maintenance calls.
Can These Fans Handle Corrosive or High-Temperature Applications?
Tube axial belt drive fans excel in demanding conditions beyond just explosive atmospheres. For corrosive environments like chemical fume exhaust, select models with epoxy-coated steel or aluminum construction and stainless steel hardware. The belt drive configuration keeps motors away from corrosive vapors, significantly extending equipment life compared to direct drive options. Temperature capabilities vary by model, with standard units handling up to 140°F continuous duty, while high-temperature variants with special bearings and belts operate reliably up to 300°F. For paint booth exhaust or solvent recovery systems, spark-resistant aluminum wheels provide an extra safety margin while resisting chemical attack.
