BFAG BFAG Series explosion-proof exhaust fan exhaust fan for the environment 1 and Zone 2 hazardous locations. IIA, IIB explosive atmosphere. BFAG Series Features Explosion-proof exhaust fan exhaust fan from the explosion-proof motor, blades, hair dryer and other components. Low noise, low power consumption, reliable explosion-proof performance. Cabling. Spindle speed (or motor power or wind) can be selected according to user requirements. Explosion-proof mark: ExdIIBT4 comply GB3836-2000, IEC60079 standards.

Check all fasteners are complete, tighten, there should be proof certificate number. 2, line voltage must match the motor rated voltage. 3, with 500V megger check motor insulation resistance, the resistance value if less than 5MΩ, then the application or the short-circuit current method drying method for drying treatment, so the insulation resistance is greater than 5MΩ. 4, must be equipped with a small explosion-proof switch for the power switch, or the common switch is mounted on the outside of the place no danger of explosion. 5, connect the power cable diameter should be consistent with the ring, tighten the compression nut should ensure that after the cable between the seal between the gasket and the outlet hole with no gap, or they will lose the proof performance. 6, the assembly should be guaranteed proof gap is less than 0.2mm, replace the motor bearing grease, the grease grades for the ZG-2H complex calcium-based Run. 7, part of the non-explosion-proof electrical wiring not disassemble, wiring, open wiring compartment cover, penetration leads to terminal. Connected, close the cover and tighten the screws to make it flameproof gap is less than 0.2mm, and then tighten the outlet device, the leads can not traverse. 8, using the exhaust fan motor should always be cleaned of dust and other sediments, in order to avoid the impact of heat.
