Exhaust fan wholesale price Hotline: Foshan Lan Yu ventilation equipment, including professional development and production of evaporative air conditioners, portable air conditioners, exhaust fan, suction fan, curtain walls, including a variety of 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 achieved by the automatic control system to automatically open and close to dust the fan louvers, waterproof, 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! Scope: Almost all require cooling, ventilation, ventilation of premises can be used, such as supplier factories, supermarkets, offices, hotels, hospitals, railway stations, stadiums, dance halls, auditoriums, conference rooms, schools, cafes, workshop and other places . 2, suitable for high temperature or smell of industrial production plants, such as chemical, textile, electronics factory, machinery plants, etc., can also be used for job or full cooling ventilation. 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. Principle of negative pressure suction fan ventilation exhaust air outside the indoor unit pressure drop, indoor air thinned to form a negative pressure zone, air flows into the interior due to barometric pressure compensation. In practical applications, industrial plants, centralized suction fan mounted on the side of the plant, factory air intake located on the other side, the air intake by mouth suction fan convection hair. In this process, near the suction fan to keep doors and windows closed, forcing air from the air intake flow into the workshop, the workshop flows discharged from the suction fan shop. Negative pressure ventilation fan thorough, efficient ventilation rate of 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. Within a few minutes from the fan turned out negative pressure exhaust fan factory indoor air pressure falls, indoor air thinned to form a negative pressure zone, air flows into the interior of compensation due to the 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.
