THERMACTOR Air System
Individual systems may vary in number and type of components, depending upon engine size and application but all systems use the same basic components. A typical system consists of an air supply pump, air by-pass valve, centrifugal filter, check valve(s), air control valve, air manifold and air hoses.
In the Managed Thermactor Air (MTA) system, air can be by-passed to the atmosphere by a thermactor air by-pass valve and/or directed near exhaust manifold, or underbody catalytic converter. Some models may use a combined air by-pass/air control valve.
