◆材质：铝合金型材

◆规格尺寸：W*H尺寸可依据设计制造

◆特性：

1.适用于具有正压的空调房间自动排气，依靠叶片的自重而自然下垂，隔绝室内外的空气交换。

2.当室内气压大于室外时，气流将百叶片吹开而向外排气，反之，当室内气压小于室外时，气流不能反向流入室内，具有单向止回作用。

表面处理：静电喷塑

外框边宽尺寸E有2种：23mm,32mm

当E=23时，h=40，面尺寸=颈尺寸+37

当E=32时，h=50，面尺寸=颈尺寸+54

◆Material: aluminum alloy profile

◆Size: W*H size can be designed and manufactured

◆Characteristic:

1. It is suitable for automatic exhausting of air-conditioned rooms with positive pressure, depending on the self-weight of the blades, naturally sag, and isolates the air exchange between indoors and outdoors.

2. When the indoor air pressure is greater than the outdoor, the air flow blows the louver and exhausts outward. Conversely, when the indoor air pressure is smaller than the outdoor air flow, the air flow cannot flow back into the room, and has a one-way check function.

Surface treatment: electrostatic spray
