Maintenance

Daily Maintenance
Verify, during full load (maximum compressed air delivery) operation, the IQ System filter
restriction is not excessive. Filter restriction can be checked at the control panel. The
compressor will shutdown if restriction exceeds recommended values.
Excessively restricted filter elements may cause an increase in the
amount of aerosol water and oil carryover, which could result in damage
to downstream equipment. Normal service intervals should not be
exceeded.
Weekly Maintenance
• Remove Y-strainer screens at the bottom of the moisture separator and both filters.
Clean out any residue.
• Verify the orifices below the Y-strainers are not clogged.
• Verify the piping from the orifice purge points to the exhaust system is not clogged.
Blockage of the Y-strainers, orifices, or piping can result in flooding of
the vessels with condensate. If flooding occurs, excessive condensate
may enter the airstream and could result in damage to downstream
equipment.
Yearly Maintenance
The normal maintenance interval on the primary and secondary IQ System filter elements is
one year (earlier if pressure drop becomes excessive). High filter restriction will shutdown the
compressor if restriction exceeds recommended values.
Excessively restricted filter elements may cause an increase in the
amount of aerosol water and oil carryover, which could result in damage
to downstream equipment. Normal service intervals should not be
exceeded.
