silencers: rectangular silencers
Rectangular silencer TP
TP plate silencers are made as rectangular ducts with damping plates.
There are three types of silencers to choose from:
- 200/100 – silencer with 200 mm thick plates and 100 mm gap. Used at a flow of 2000 m3 / h
- 100/50 – silencer with 100 mm thick plates and a 50 mm gap. Designed for smaller amounts of flowing air. It demonstrates to a greater extent more favorable damping values.
- 100/100 – silencer with plates 100 mm thick and 100 mm gap. Due to the large flow area, it has a lower pressure loss.
The silencer is made as a standard ventilation duct with inserted damping plates. The plate is made of a casing and several layers of mineral wool. The channel and plate are permanently connected to each other.
The TP silencers are designed for operation at pressures from -400 to 630 Pa.
When selecting a silencer, it is not recommended to exceed 12 m / s air velocity inside the silencer.
The dependencies of air flow velocity Vn on the TP silencer from the flow velocity Vt
| Type TP | % free cross-section | Air flow speed Vn | ||
| Vt = 8 (m/s) | Vt = 10 (m/s) | Vt = 12 (m/s) | ||
| 200 – n – 100 | 33 | 2.6 | 3.3 | 4.0 |
| 100 – n – 50 | 33 | 2.6 | 3.3 | 4.0 |
| 100 – n – 100 | 50 | 4.0 | 5.0 | 6.0 |
