FBDNO5.0 / 2 × 7.5 local fan mine local fan, flameproof local fan, push-local fans, local rotating axial fan, local fan, flameproof push- local rotating axial fan, FBDNO.5.0 / 2 × 7.5 local fan FBDNO5.0 / 2 × 7.5 flameproof push-rotating axial local fan, mainly for mine and other industrial sectors transport with gas and coal dust and flammable gases, for coal, metal mining, chemical mines and other mines mining excavation, well construction, local exhaust ventilation and tunnel ventilation and other long distance. According to the ventilation requirements are different, the fan can be used alone, but also two run simultaneously. FBDNO5.0 / 2 × 7.5 local fan Main technical parameters: Model: FBDNO5.0 / 2 × 7.5 Airflow :240-170m3 / min total pressure :360-3280pa power: 2 × 7.5kw maximum total pressure efficiency: ≥ 75% Noise: ≤ 30db FBDNO.5.0 / 2 × 7.5 local fan, low noise, the fan housing is made of outsourcing double silencer, fan silencer at each end, so that the fan noise control at run time below 80 decibels (A-weighted sound level than at 22 decibels), you can change mine noisy environment, improve the working environment of workers. sdnkfdsSD
