    Hvac Ventilation System Aluminum Stationary Louver Gravity Shutter

    Gravity Louver:

              It applies to air conditioning room with positive pressure. It exhausts air automatically. Usually the blade is vertical, it isolates the air circulation between indoor and outdoor. When the indoor pressure is bigger than the outdoor pressure, the air flow blows the blade and the inside air is exhausted. The air isn’t able to flow into room if the indoor pressure is smaller than outdoor pressure. It has single-track non-return function. Air volume damper that adjust air volume and air speed or filter that decrease dust and purify air can be set up in the back of air outlet according to customer’s requests.

     

    We use high quality extruded aluminum to produce the gravity louver which is usually used on the outside of walls. This aluminum louver design is intended for air extraction and automatic closet of duct, when the air equipment is switched off.

     

    GL-VA gravity louver has been anodized. It can be accurately adjusted for smooth performance. Optional colors are RAL9010 and RAL9016. Only when the exhaust fan is running that the blades of this type air louver can be opened. The blades will close automatically to preventing rains , dust, insects from getting inside rooms, one the exhaust fan is turned off.
