NSR-125 # Fan Brand Model NSR NSR-125 type blower airflow direction of the cross-flow fan Material steel low pressure blower fan blower performance low noise fan-use products are widely used in pneumatic conveying, water treatment, vacuum packaging, aquaculture, chemical, petroleum, metallurgy, electric power, food and other industries and sectors weight 408-521 (kg) power 5.5-30 (kw) wind 4.93-13.39 (m3 / min) Boost 9.8 ~~ 78.4 (kPa) Features: (1) high pressure The maximum boost to 78.4kpa. (2) Roots blower exhaust characteristics mandatory aspirated with a hard, that when the pressure changes, the flow changed little. In other words, pressure may be within the allowable range "Automatic" adjustment, and the flow change is small. (3) the pressure change with system resistance varies, adaptive. Roots blower no internal compression, the system needs much pressure, matching motor power under the conditions allowed, blower can provide much pressure, so the pressure is self-adaptive. (4) The fan is compact, small size and light weight. (5) The transmission medium is not oil. Leaving a narrow gap between the rotor and the rotor and the blower cabinet, wall panels, high-speed operation of the rotor and do not contact, so no need for lubrication of the rotor, so the media is not oil. (6) Roots blower high efficiency, low energy consumption. Roots blower rotor with special design, meshing curve for advanced composite line, sealed, leak less, volumetric efficiency is further improved. Description: NSR series Roots blower is my company after careful research and well-designed, well-made independent research and development, which contains two self-developed patents. Fans of the series, small size, light weight, high traffic, low noise, smooth and reliable operation. In energy saving, environmental protection has made its own contribution.
