Flue silencer DN180

Compact flue silencer for significant reduction of operating noise from condensing boilers and standard combustion appliances in both negative and positive pressure operation. Tightness and maximum temperature depend on the seal material used: without a seal it is suitable for positive pressures up to 1,000 Pa and 400 °C, with EPDM up to 200 Pa and 200 °C, and with silicone up to 200 Pa and 120 °C.
The durable silencer consists of a stainless steel housing with a water-repellent mineral fibre absorption core, protected by glass fleece and a perforated sheet metal sheath, and the special mineral fibres provide very good attenuation at medium and high frequencies. Thanks to its short installation length, this silencer is particularly suitable where space is restricted.
