California Code: Unit may comply with California Code 462 (l) (2)/

units that comply with California Code.
unloader Blow-off Pressure: All models are continuous running
units controlled by air tank pressure. When the maximum air tank
pressure is obtained, the unloader valve will blow-off. This will
cause the compressor to exhaust the air to the atmosphere and
not the tank. This decreases the load on the engine and allows it
to run at a near no-load condition.
unloader reset Pressure: When the air tank pressure drops to
a predetermined point, the unloader valve closes. The air tank
pressure will now increase until it reaches the unloader blow-off
pressure.
