Suction fan wholesale price Hotline: Foshan Lan Yu ventilation equipment, including professional development and production of evaporative air conditioners, portable air conditioners, vacuum blower, curtain walls, including a variety of suction fan ventilation equipment, etc. ... Details : Model: JF-1530 扇 mouth + diameter (mm): 1400 rpm fan (r / m): 325 Air flow (m3 / h): 55800 Noise (dB): 65 Power (kw): 1.10 Rated voltage ( V): 380 Weight (Kg): 80 Dimensions (mm) length X width X thickness: 1530X1530X400 Features: Shades automatically open and close to dust, water fan louvers by the automatic control system, beautiful effect. Low noise, large air volume, low power consumption, cooling effect is obvious; both hair, but also ventilation, quality assurance and other greenhouse cooling ventilation best choice! 1.40 m aluminum fan blades Technical features: CAD / CAM design and manufacturing optimization, with a total pressure, air volume, low noise, low energy consumption, stable operation, long life and other characteristics; shutters automatically open and close to dust, water, nice; either hair, but also ventilation, greenhouse, factories and other cooling ventilation best choice. Special installations can be customized dual-network or dual network + venetian type fan. Dual-network fan mainly for indoor space is too large to enhance air flow, making the fan relay. Dual network + venetian type fan for the lower factories and other places to install, easy access to manpower blades, high safety factor. Utilizing the principle of evaporative cooling suction fan, generally in the outdoor air through the wet curtain, by the evaporation of water absorbs heat, leading to air cooling, become cool air, the indoor temperature effective cooling, another feature of the wet curtain cooling ventilation system that the cooling process the dust filtered outdoor air exhaust, the oxygen content of the intake air increases, the air introduced into the plant within a fresher, more preferably operating environment for air quality. After the end of the installation in the plant's cooling equipment wet curtain wall, while the other end of the suction fan is installed, apply suction fan inside the hot air out of the plant, resulting in less than outdoor indoor Kia Kia, prompting the outside air through the wet curtain piece cooling, variable into the cold air into the interior of the plant, to the cooling effect, thereby creating a comfortable, cool, idle factories negative work environment exhaust fan outside the indoor air pressure falls, indoor air thinned to form a negative pressure zone, the air due to the compensation flowing into the indoor air pressure difference. In practical applications, industrial plants, plant negative pressure exhaust fan installed in the plant to focus on one side, the air intake to the plant room on the other side, the air intake by mouth suction fan convection hair. In this process, the suction fan near the doors remain closed, forcing air to flow from the air inlet side shop windows compensation. Air lined up orderly inflow from the air inlet workshop, from workshop flow, negative pressure ventilation fan discharge from the plant shop. Ventilation thorough, efficient ventilation rate can be as high as 99%. Through specific engineering design, according to the need to design ventilation rate and wind speed, any fever, harmful gases, dust can quickly exhaust smoke shop, any disposable poor ventilation can solve the problem. From a few seconds to turn on the exhaust fan ventilation can achieve results.
