The Dhumal Air Inlets steers the incoming fresh air before it enters the building. The air gets its direction through adjustable spoilers. The amount of air is regulated with a vertically moving slide. Steering and amount of air are separated. Because of this completely situations where high demands on the air control should be imposed
Note:The position of the spoilers has a big impact on the capacity of the air inlet. The picture below illustrates this for the Air Inlet. Therefore Dhumal advices to calculate with 10 Pa under pressure.
| Spoilers Normal | Spoilers Up | Spoilers Extreme |
|---|---|---|
| Surface – 1,570 cm2 | Surface – 1,480 cm2 | Surface – 1,150 cm2 |
| 10 Pa – 2,400 m3/h | 10 Pa – 2,100 m3/h | 10 Pa – 1,750 m3/h |
| 20 Pa – 3,300 m3/h | 20 Pa – 3,000 m3/h | 20 Pa – 2,450 m3/h |
| 30 Pa – 4,100 m3/h | 30 Pa – 3,650 m3/h | 30 Pa – 3,000 m3/h |
| 10 Pa – m3/h | 2,100 |
|---|---|
| 20 Pa – m3/h | 3,000 |
| 30 Pa – m3/h | 3,700 |
| Surface cm2 | 1,415 |
| Width – mm | 510 |
| Height – mm | 400 |
| Depth – mm | 80 |
