Silenziatore rettangolare flangiato (50 mm lana di vetro)
Numero articolo: 5072
Silencer
Easily-fitted silencer immediately before or after the KE, KT, RS and RSI rectangular duct fans. Effectively suppresses noise transmitted to the duct. The silencer should be used together with an insulated fan where there is a requirement for noise suppression both in the duct and in the surroundings as a whole. All silencers are supplied with a universal flange suitable for PG flange or Metu profile.

Pressure drop calculation for rectangular silencers These calculations apply only if the silencer is connected to a duct at both ends. Example: Calculation of pressure drop for the LDR 60-35 (with dan model RSI 60-35 M3~) using the diagram to the right. 1. Start by defining the front area, see the table below. 2. Move horizontally to the right until you reach the designated air flow in diagram B. 3. Go up vertically to diagram A and the correct p value (see the table). 4. Then continue horizontally to the left and read off the pressure drop. In this example, the pressure drop is 27 Pa.
