Aluminum Double Deflection Grille

Double Deflection Grille (common: double leaf) is equipped with standard or split air flow control valve (OBD). Unlike ASE single leaf, it has two layers of unidirectional blades that can be adjusted individually to control the air flow direction up, down, left, and right, while the air flow control valve provides air volume control. ASD is very suitable for industrial and commercial, residential, restaurant, parking lot and toilet environment applications.

邊框計算公式

    邊框 頸計 天花留吼 風喉窿 頸高
    20mm B-24mm B-14mm B-19mm 50mm
    25mm B-36mm B-26mm B-31mm 50mm
    32mm B-50mm B-40mm B-45mm 50mm
    • B=Base Size (面計)
    • 假設選用了25mm邊，面計300mm
    • 頸計=264mm
    • 天花留吼=274mm
    • 風喉窿=269mm

其他邊框/做法

    • 少於20mm邊框一律不建議
    • 愈窄的邊框將影響外觀及硬度較少導致安裝扭曲
    • 愈窄的邊框需要更精準的天花開窿

常見問題

    1. 頸可以做薄嗎?
    • 不能，雙葉頸深至少50mm。少於50mm可以考慮使用單葉(ASE)，單葉只需要25~32mm。
