The fans is suitable for climatic conditions of Y-type, allocation categoryNo.5 in compliance with GOST 15150-69.The fans are axial-flow single-stage with horizontal rotation axis, explosion-proof, the level of explosion protection is PB Exdl (PB 3B).Explosion-proof electric motor 3BPM280S4 with the housing able to withstand gas explosion pressure inside the motor (in case of explosion), plus fan’s compliance with the necessary parameters of joint size, air-gaps and upholding contamination class of mating surfaces in accordance with GOST R 51330.0-99, GOST R 51330.1-99 provide explosion protection.The fans are allowed to be used as main ventilation fans.Advantages:
- hi-tech aerodynamic scheme with high pressure characteristic allows to get high parameters of air delivery
- suitable for air pipes with diameter 1000 and 1200 mm
- if it’s necessary to rise air pressure in the face of a rather long mine hole, fans’ design offers concatenating of two or more fans
- fans provide stable long-term 24-hour ventilation
- if required, the fan can be equipped with a muffler
- economic
- thermal shutdown protects motor winding from overheat
