Silencer for Vacuum Generator VVV.

Detailed Safety Instructions


1.If the silencer (VVSR06L) is not used or if centralized exhaust piping is used, air may flow back through the exhaust port (EX) when operation is stopped, and dust in the air or piping may enter the product, affecting product performance.

2.When using a silencer with an elbow adapter, the suction flow rate will be about 15% lower than the specification value.
