Working principle of the warning indicator

The design is based on a two-chamber system with an inner and an outer silencing chamber. The inner diffuser serves as a warning indicator that is pressed out when backpressure is too high. In certain systems, the warning indicator may be partially extended after initial use. This is normal - the silencer then provides optimal flow and correct backpressure. It is time to replace the silencer when the inner diffuser extends far enough to show the red marking on the warning indicator.

Silvent’s new series of safety silencers offers extremely effective noise reduction, compact size and a unique and patented warning system. The silencer’s warning indicator gives early warning that backpressure in the system is too high. Maintenance personnel can both see and hear (by an elevated sound level) that it is time to replace the silencer before costly and unnecessary operation disturbance occurs. Since the warning indicator extends when it is pressed out, it is also possible to use electronic monitoring to stop the machine for silencer replacement. These safety silencers provide noise reduction of 30-35 dB(A). Silvent offers four different dimensions. Patented.
