>>>Negative-pressure cooling principle:

Its operation principle is a physical phenomenon--evaporating water,taking in heat.Installing  fans in one side of a closed workshop and equipping cooling pads in the other.The fan will draft the hot air away,and negative-pressure will be in the room to make a pressure gap between inside and outside,then, the air outside through the cooling pad will be cooled,exchanging the heat with the inside air to make the inner door air fresher,cooler and wetter.

>>>Parameter:

>>>Product Characteristics:

1) The optimal design and construction made by CAD/CAM, with high full pressure, big air volume, low noise,little energy-lost, stable running and being well for ages; The louver with pleasing shape can open and closed automatically, having dust-proof and water proof; with its double-function: cool breeze blowing and air draft, it is the best cooling and ventilating product for factories etc.

2) 6 blades design is for increasing airflow owing to the blade is make of intensified resins vane or aluminum vane.

3)The motor enjoys high efficiency and energy-saving which makes it possible to work easily under the high pressure surrounding

>>>Application:

1) Industrial fields: textile, socks/clothes making, glass, molding, rubber, coating, silk-screen printing, toy, electronics, home appliances, shoe making, printing, food stuff, processing, dyeing, laundry and other workshops with high temperature.

2) Civil fields: net bars, stores, supermarkets, mess hall, food markets, waiting-rooms and recreation places and other occasions with air-conditioning.

3) Agricultural fields: large farms, greenhouse and livestock farms, etc.
