Exhaust Brakes

A fixed orifice exhaust brake, is the most cost effective supplemental braking solution. The term “fixed orifice” refers to a hole in the butterfly valve, which allows a set amount of exhaust bypass at a pre-determined engine speed. It does not have any pressure regulation mechanism, which makes it an economical choice over a higher performance, pressure regulating exhaust brake, such as the PRXB.

Pacbrake’s PRXB has revolutionized modern day exhaust braking with its patented design. Being home to the only exhaust brake on the market with a true variable orifice, the PRXB displays constant remarkable backpressure and the strongest braking horsepower.
