1 Purification Filters - Each filter cleans the air for that specific compressed air
stage in the cycle. Removes oil, moisture and debris. The actual number of
purification filters depends on the Horse Power of the motor.
7.5HP & 10HP=2
15HP= 3
20HP=4
2 Safety Switch Reset Push Button - If the compressor output pressure reaches
to 7300PSI, the mechanical pressure switch will signal the controller to stop
the compressor from running. When the pressure returns to normal and the
safety switch reset push button is pressed, the compressor will be able to
resume running.
3 Condensate Container - Collects the moisture and oil that is produced during
the air compression process.

the excess current draw by the motor or the optional motor saver senses
electrical faults, the motor O/L reset push button must be pressed after the
electrical condition returns to normal for the motor to resume running.
5 Motor Saver - Optional feature depending on the model. Protect 3-phase
motors from: high voltage, low voltage, voltage unbalance, reverse-phase,
overcurrent, undercurrent, current unbalance, single-phase, ground fault,
