Bathroom zones are just a way of telling which extractor fan you can install in a specific place.
Tecsound circular spigoted attenuators offer excellent sound absorbing properties. Suitable for temperatures up to 200oC and a maximum pressure of 1500 pascals. Our silencers are of the absorption silencer type. The damping ability of absorption silencers is affected by the geometric design of the silencer and the type of damping material chosen. There are variants, with different properties.
Method of measurement: The silencers are tested in accordance with ISO 7235 "Acoustics - Measurement procedures for ducted silencers - Insertion loss, flow noise and total pressure loss".
Design: The straight types consist of an outer and inner sheet casing. The space between them is filled with mineral wool of varying type and density. The outer sheet casing of the circular curved silencers are built as a segmented bend, BFU.
Baffles, one or more, for better noise attenuation, exist in SLCBU, SLBGU, LRBCB models which are custom made to order. The tear of fibre is prevented since all exposed surfaces are lined. The connections of the circular types are supplied with a Safe-gasket.
