Dual Skin Exhaust



Our dual skin exhaust are made from the highest quality material and craftsmanship to ensure lasting performance.

Dual Skin exhaust are used to reduce the surface temperatures to below 150ᵒC so that there is no need to use Thermal Blankets. This reduces the chance of a fire caused by flammable/combustible fluids coming into contact with temperatures above 150ᵒC.

All of our OEM exhaust systems are manufactured to fit your machine’s existing brackets and footprints, which means easy removal and replacement.
