Foshan Lan Yu ventilation equipment specializing in the development and production, including evaporative air conditioners, portable air conditioners, vacuum blower, curtain walls, including a variety of ventilation equipment, etc. ... Description: 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 Shape Dimensions (mm) length X width X thickness: 1530X1530X400 Features: Shades automatically open and close to dust, water, beautiful effect fan louvers through automatic control system. 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, leisurely work environment fan features: 1. frame and shutters are made of galvanized steel mold manufacturing. 2. Disposable blades stamping, forging gas using screw fastening, the computer precision balance calibration. 3. Low noise, high winds, smooth and reliable operation. 4. blinds fittings manufactured using high strength steel materials, closed tight, long service life. 5. Motor 380V / 220V is optional. 6. Fans of the series is the most important feature of air volume, low noise, good looks, smooth operation, easy maintenance, low price; this product is available in humid, corrosive gases under normal use in harsh environments, is widely used in flower garden greenhouse ventilation ventilated livestock ventilation and cooling, textile workshops and other cool places.
