Aluminium alloy tuyere secondary oxidation coating full aluminum alloy structure, using stainless steel plate, galvanized steel plate material for rain and fire protection in any climate conditions, and can be assembled into large-scale shutters to achieve the largest overall air flow . Good sound insulation characteristics, the movable blade is sandwich type, and the sound insulation material is inlaid between the layers.
Because the material of the aluminum alloy air vent structure is all made of high-quality aluminum alloy, plus special processing technology, the noise reduction shutter can be used in any climate conditions. The border, bottom border, louver, and side borders are deformed.
Aluminum alloy air vent can minimize the airflow transmission resistance and reduce noise. It can be assembled into a series of aluminum alloy air vent size noise louvers according to the requirements.
