1, compact structure, easy installation, reliable operation: The fan than in the case of the same amount of wind, air pressure axial or centrifugal small size, can be directly connected swf exhaust fan and duct, horizontal or vertical installation, easy operation; 2, low noise: The fan housing has been specifically designed to reduce the outflow of noise htfc larger exhaust air box, air volume in the unit, the unit pressure working conditions, than A sound level can be reduced by 2 -3dB (A), while in the case of low speed roof exhaust fan, the fan can obtain higher pressures. In the mining industry, and senior civil relationship can replace the low-pressure exhaust system or replace the high-pressure centrifugal fan axial fan silencer without requiring extensive measures. 3, wide application: This series of products at single-speed and two-speed two models, according to different occasions exhaust fan, fan mounting angle change, change the number of leaves and the wind speed reaches its requirements. SWF series mixed flow fans included in the national "Spark" project, with the same amount of wind machine number relatively large centrifugal fans, axial flow relatively high pressure fans, and other characteristics can be axially mounted. . Positive pressure blower is used when there is a certain regulations, but many consumers have been carried out in accordance with their own unique way, in fact, positive pressure blower use, we must follow the maintenance system for positive pressure blower conduct maintenance, today, small series simply to introduce the next bar. A positive pressure blower must be someone at runtime, personal service. 2, the fan is running, if you detect a problem, be sure to stop running, maintenance, operation can not be sick. 3, positive pressure blower repairs must be emphasized first stop power outages. 4, in addition to the lubricant should be replaced after each overhaul, but under normal circumstances, change the oil from March to June. 5, periodically clear the fan inside the dust, especially dust on the impeller, dirt and other impurities in order to prevent corrosion and imbalance. htf exhaust fan, exhaust fan, air conditioning provided by the Texas Watson Watson air-conditioning plant.
