Catalytic Silencers Model QAC (QUICK Access Catalyst)

QAC is the industry standard catalytic silencer for gas reciprocating engines. QAC combines tried and trued silencing technology with an innovative catalytic housing. Ease of use, guaranteed emission control and noise abatement define the Maxim QAC line. The QAC catalytic silencer uses only 4 nuts to hold the catalyst housing lid in place. Each element is held in place by two bolts, attached to pressure bars, to ensure perfect sealing without the use of a gasket.
