Silvent SIS-04

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.
