Aluminum Linear Bar Diffuser
Aluminum Linear Bar Diffuser (commonly known as: Linear Bar Diffuser) is one of the air outlets most widely used in air conditioning or exhaust systems. Model ALD is made of high-quality aluminum alloy. If two pieces are connected together, it can create a one-way effect. It can also be equipped with a regulating valve and a light shield for the false air outlet without having to break the air outlet due to the air duct. It also provides angular sections of any specified degree to connect the linear bar Diffuser to any corner of the room.
Border Calculation Formula
- B = Base Size (Meter)
- Assuming a 20mm edge is chosen, the face value is 150mm.
- Neck gauge = 120mm
- Ceiling height = 130mm
- Air vent hole = 125mm
- 16mm edge = meter length - 22mm = inner neck measurement (hole opening = meter length - 15mm)
- 12mm edge = meter reading - 14mm = inner neck measurement (hole = meter reading - 10mm)
| border | Neck | Tianhua left a roar | Wind throat | Neck height |
| 20mm | B-30mm | B-20mm | B-25mm | 20mm |
| 25mm | B-42mm | B-30mm | B-35mm | 20mm |
| 32mm | B-56mm | B-45mm | B-50mm | 32mm |

Frequently Asked Questions
Q: With a 20mm frame and a 150mm vent surface, how many holes should be left in the ceiling?
A: Subtract 26mm from the inner neck (124mm), so a 130mm opening should be left.
(6mm is the thickness reserved for blackening and connecting the bellows material)
