Characteristic Feature:

• Designed with high efficiency, Exhausted ultra air flow ;Low rotational speed, Low noise, Low power consumption.
• Designed with special diversion, reduce impeded by air; The blades pulley are corrected by the balance, steady.
• I unit product more efficient an area of over 100 square meters; Neither any capacity, Nor the tube pipe, Any where is installed.
• The shutter is cool-resisting, anti-ultraviolet rays, any kind of weather, environment is suited; the shutter obeys the theory of positive air flow, no power consumption, no switch . and keeps out of the rain also.
• Housing of F.P.P reduce the metal sympatheic response, and light material, and resisting the acid, Soda, hot heat, cool, wet, etc. increase service life.
