4. Sight Glass:

A window through which the level of oil can

be checked visually.

5. Magnetic Oil Drain Plug:

Removal allows for drainage

of oil from pump. Attracts metal particles that could

damage pump.

6. Intercooler:

Cools the compressed air as it travels

between stages. The flywheel/fan creates an air flow that

rushes past and cools the intercooler.

7. Aftercooler:

Cools the compressed air from the pump

before it enters the receiver tank. The heat from the

compressed air is transferred outward to the cast iron
fins of the Aftercooler, the flywheel/fan creates an air

flow that rushes past and cools the cast iron fins.
