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)
