FAQ

The sintered bronze element is a porous material that diffuses the exhausting compressed air through countless tiny passages. This process slows down the air velocity and breaks up the sound waves, effectively reducing the noise level without creating excessive back-pressure that could hinder system performance.

Yes, under certain conditions. The ASCO 34600003 can be cleaned by back-flushing with a solvent or compressed air to remove contaminants like oil or dust that may clog the pores. However, given its low cost, replacement is often the more practical and reliable option to ensure optimal performance.

The G 3/8 thread, as used on this silencer, is a British Standard Pipe Parallel (BSPP) thread. It creates a seal using a washer or O-ring on a flat surface. An NPT (National Pipe Taper) thread is tapered and creates a seal through the interference fit of the threads themselves, typically requiring sealant tape. It is crucial to match the thread type to your equipment's port to ensure a proper, leak-free connection.
