Sullair Industrial Air Compressor SN75V

Is the maintenance gauge showing red with the compressor running full load?

Has it been a year since the last air filter maintenance?

If either of the above checks is true, proceed with the following steps.

Clean the air filter’s exterior housing.

Release the hold-down clips and remove the end cover.

Remove the air filter element by pulling it out of the housing.

Clean the housing interior with a damp cloth. Do not blow dirt out with compressed air.

Reassemble in the reverse order.

Drain the separator/sump tank and change the compressor fluid using instructions shown below:

Lubricant:; Sullube® (7.2 gal / 27.3 L): Fluid change - E, Fluid filter change - G, C, Separator change - I, D

PristineFGTM (7.2 gal / 27.3 L): Fluid change - H, E, Fluid filter change - G, C, Separator change - B, D

B—4,000 hours or more frequently if conditions so require.

C—When measured pressure loss exceeds 20 psig (1.3 bar).

D—When measured pressure loss exceeds 10 psig (0.7 bar).

E—When required by fluid analysis or known contamination.

F—Does not require replacement during normal service conditions.

Warning: High-pressure hazard. Relieve all pressure from the separator/sump tank and all compressor lines.

Pressure relieved from the separator/sump tank and all compressor lines?

All piping disconnected from the separator cover plate?

Twelve (12) hex head capscrews(5⁄8 in × 21⁄2 in) and lock washers removed from the cover plate?

Cover plate lifted from the separator/sump tank?

Old gasket material scraped from the underside of the cover plate and the separator/sump tank flange?

Separator/sump tank inspected for rust, dirt, etc.?

New separator element inserted into the separator/sump tank without denting the element against the tank opening?

Warning: This maintenance check requires trained personnel with PPE!

Unscrew the sight glass assembly where the elbow fitting joins the strainer/filter

Remove used filter assembly, and replace with new assembly

Inspect and clean the orifice inside the sight glass blocks. The orifice must be removed with an allen wrench

Coat/lubricate the O-rings with silicone grease

Reattach the connectors to the sight glass/orifice blocks

Sign off on the oil return/sight glass maintenance

Warning: Ensure the air compressor is turned off and cooled down before starting the cleaning process.
