Gravity Louver

GL-VA

We use high quality extruded aluminium to produce the gravity louver which is usually used on the outside of walls. This aluminium 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, once the exhaust fan is turned off.
