NSR-40 # blower brand NSR Model NSR-40 type blower airflow direction of the cross-flow fan Material steel low-pressure blower fan fan performance low noise fan-use products are widely used in pneumatic conveying, water, vacuum packaging, aquaculture, chemical, petroleum, metallurgy, electric power, food and other industries and sectors weight 75-85 (kg) Power 0.75-2.2 (kw) air volume 0.29-0.95 (m3/min) Boost 9.8 ~ ~ 58.8 (kPa) features: (1) high pressure The maximum boost to 58.8kpa. (2) Roots blower with a hard mandatory aspirated exhaust characteristics, that is, when the pressure changes, the flow has changed little. In other words, the pressure within the allowable range can be "automatic" adjustment, while a smaller flow changes. (3) changes with the system pressure resistance varies with adaptive. Roots blower no internal compression systems require much pressure, matching motor power under the conditions allowed, Roots blower can provide much pressure, so the pressure is adaptive. (4) The fan compact structure, small size and light weight. (5) the transmission medium is not oil. Leaving a narrow gap between the rotor and the rotor and the Roots blower cabinet, wall panels, high-speed operation of the rotor and do not contact occurs, so no need for lubrication of the rotor, the medium is not oil. (6) Roots blower high efficiency and low energy consumption. Roots blower rotors are specially designed for the advanced composite curve meshing type 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 self-developed two patents. Fans of the series is small, light weight, flow, low noise, smooth and reliable operation. In energy conservation, environmental protection has made its own contribution.
