Flower greenhouses. High-tech agricultural demonstration garden and industrial plants warehouses and other places of ventilation ventilation temperature adjustment empty product at low operating costs. Good performance is stable and reliable quality, has been unanimously praised the majority of customers, products are sold throughout the country Features machine using CAD / CAM design, with low investment costs , air volume, low noise, low energy consumption, stable operation, long life, high efficiency, automatic shutters closed from dust, water, nice; either hair, but also ventilation, cooling ventilation is the best modern workshop selection. Environmental protection, energy saving ventilation and cooling suction fan will become mainstream devices market. 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 Lan Yu Fan Features: 1. frame and shutters are made of galvanized steel mold manufacturing. 2.
