Restrictions
- Warning: Nonhazardous location ventilators are not interchangeable with hazardous location ventilators. Note: Installation must comply with all local and national safety codes including the National Electrical Code (NEC) and National Fire Protection Act (NFPA).
Hazardous Location Centrifugal Belt-Drive Exhaust Ventilators
- Designed to exhaust air in commercial and industrial applications with potentially hazardous particles or fumes. Constructed with spark-resistant aluminum wheel and rub ring. Spun aluminum housing features rolled wind band to increase stability. Motor, drive frame, and wheel are isolated from the mounting base by independent neoprene studs no metal-to-metal contact, greatly reducing overall noise. Motor compartment is cooled by fresh outside air, maximizing motor life. Motors, sheaves, belts, and conduit kit are packed separately when unassembled ventilator with drive package is ordered.
- Aluminum, backward inclined, nonoverloading centrifugal wheel design Air handling-quality bearings meet min. L10-100,000 hr.
- Downblast Ventilators
- Motor only UL Listed for Class I Groups C & D and Class II Groups E, F, & G hazardous locations Max. inlet air temp.: 180 F Bearings sealed pillow block up to 16-3/4" wheel dia.; regreasable pillow block for 18-1/2" wheel dia. and larger
