Our air governors are tested for air-pressure build-up, leakage, and unloader functionality.

The D2 governor operates with the unloader mechanism of the compressor which automatically controls the air pressure in the air brake system between a minimum and maximum pressure. The compressor runs continually, but the compression of air is controlled by the governor.
