Dwell SLF 100-200 Flexible Duct Silencer
Silencer is applied for noise absorption produced during the ventilating equipment operation and spread along the ducting systems. Suitable for installation into round ducts. The silencer reduces the noise level in the air duct significantly. The silencer is applied jointly with the sound-insulated fan in case of high-level requirements not only to the air duct but to the equipment altogether.
Application
- Silencer is applied for noise absorption produced during the ventilating equipment operation and spread along the ducting systems. Suitable for installation into round ducts. The silencer reduces the noise level in the air duct significantly (refer the diagram «Noise
- level reduction»). For designing a ventilation system with low level of noise emission into the environment silencers should be used together with insulated fans.
Design
SRP silencer consists of internal flexible air duct made of micro-perforated aluminum foil and laminated with polyether film. The ducts are reinforced by the scroll frame made of high-carbon steel wire and outer polyethylene sleeve. Silencer supplied with high quality 25 mm sound insulation material. The silencer is equipped with the connecting flanges with rubber sealing that provides the airtight connection to the air ducts. Each standards size has several length modifications.
Mounting
The silencer design allows fixing it on the round ducts in any position by means of clamps. Installation in series is preferable to attain the better effect. To prevent the flexible silencer sagging it should be fixed not only at the ends but in the middle as well.
