Histon fans Explosion-proof axial fan bt35-11 can be customized according to customer demand production proof axial fan bt35-11. Histon proof axial fan bt35-11 adequate inventory, low prices, good quality. ◎ explosion-proof axial fan axial fan is an overview of new fans in our eighties BT30-11 on the basis of improved design, it BT30-11 fan has obvious advantages: ① structure is more reasonable; ② performance greatly improved, the total pressure effect was 89.5%; ③ lower noise, noise (than A sound level) to reduce 3.6dB (A). Explosion-proof axial fan suitable for transporting flammable and non-corrosive gases, the ambient temperature must not exceed 60 ℃, widely used in general factories, warehouses, offices, residential heating ventilation or strong heat, may also have a longer intervals within the exhaust duct installed in series, to increase the pressure in the pipe, do remove free fan motor. Corrosion axial fan (FT35-11 type), the use of anti-corrosion materials coated with epoxy paint processing, motor uses special anti-corrosion motor for the transport of corrosive gases. Explosion-proof axial fan (BT35-11 type), for transporting flammable gas. Impeller machining of aluminum alloy to prevent sparks during operation, the motor flameproof motor. FT35-11-and BT35-11-type fan performance parameters and dimensions are the same as T35-11-type fan. Fan bracket feet and the need to bring the motor voltage. Please specify when ordering. ◎ Scope ● Suitable for explosive gas atmospheres 1 and Zone 2 locations; ● applies Ⅱ A, Ⅱ B, Ⅱ Class C explosive gas atmospheres; ● applies to T1 ~ T4 set temperature groups; ● widely used in oil exploration, refining, chemicals , military and other hazardous environments places as lighting, power and control wiring connections; ◎ structural characteristics ● Product Standard: GB3836.1, GB3836.2, IEC60079-1 EN60079-0, EN60079-1. ● by the explosion-proof axial fan motors, blades, hair dryer and other components. ● low noise, low power consumption, excellent performance characteristics. ● Except for ventilation, exhaust effect, but also in the long exhaust pipe installed in series interval, increasing the pressure inside the pipe. ● Case material technology for the steel or fiberglass. ◎ Specifications proof grade Exd IIBT4 corrosion protection class IP54 rating WF1 Inlet thread G3 / 4 "cable diameter inlet specifications Φ10mm-Φ14mm Cable Installation: wall (B) pipeline (D) job type (L) fixed type (G) ◎ quality assurance ● This product in strict accordance IS09001: 2000 international quality management system standards for quality control to ensure product quality is higher than the national standards fully meet the design requirements, three years of purchase, any defective product under normal use (non- human error) free maintenance by the Company.
