Standard units are set up for 175 PSIG operation. High pressure units are set for the higher 250 PSIG range and
come with the special tanks, pressure switches, pressure relief valves, pulleys and pilot valves. To determine the
pressure setting of a particular compressor check the pressure setting decal located on the air tank.
Note that 175 PSIG units cannot be converted to safely operate at pressures above 200 PSIG unless all the above
mentioned components including the air tank are replaced with 250 PSIG rated items. Refer to parts list for
applicable part numbers.
