URB 5″ Threaded Chamber Blower Silencers

URB silencers are designed for pulse control and silencing for subcritical PLV applications.

The URB and URD series are chamber silencers, a reactive type consisting of a series of expansion chambers with interconnected tubes. The URB series consists of sizes 1″-6″ and the URD series are sizes 8″-30″.  Both series are fundamentally the same in design with identical performance characteristics.  Small sizes have male threaded pipe nipples and large sizes are equipped with flanged connections drilled to 125/150 lb ANSI specifications; units in the middle, sized at 4″ and 5″ are available with either the threaded or flanged connections.

This 5″ threaded blower silencer is constructed from carbon steel, with a single coat satin alkyd primer rated for 325°F.

Chamber Silencers

These silencers are a reactive type consisting of a series of expansion chambers with interconnected tubes.  These are used on subcritical PLV applications.  When the blower is operating in the critical PLV range, a combination camber-absorptive silencer must be used for satisfactory results.
