The pressure switch allows manual control of the compressor, turning it on/off based on pressure levels. It is compatible with RolAir's electric wheelbarrow compressor models. The switch has a threaded port for easy installation directly into the tank or tank manifold. It also features an unloader port to connect the unloader line from the tank check valve. The pressure switch includes an on/off lever. It automatically starts the compressor when pressure drops below 105 PSI and stops it at the upper setpoint of 135 PSI. This OEM switch is manufactured by Square D.
