The silencers are passive design, which means they require no additional mechanices or power to work effectively and are able to remove both high and low frequency sounds. The silencers are provided inlengths measuring **0mm, **0mm, **0mm, ***0mm and ***0mm with diameters ranging from **0mm to **0mmand be placed in ducts which have both high and low air velocitites and capable of withstanding high air temperatures and still work effectively.
