  • 3/8" Pneumatic muffler with indicator

SILVENT SIS-04: Silvent's new series of pneumatic mufflers offers extremely effective noise reduction, compact size and a unique and patented warning system. The muffler'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 muffler 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 muffler replacement. These pneumatic mufflers provide noise reduction of 30-35 dB(A). Silvent offers four different dimensions.
