Maintenance
connected to the air oil tank
 Disassemble the separator element by rotating it
counter-clockwise cover to isolate the air oil tank from
the return lines, service line, etc.
 Remove the hex head bolt from the top plate.
 Swivel the top plate of the air oil tank.
 Remove the separator element.
 Scrap the old gasket material from cover and flange on
the air oil tank. While doing so, take care not to let the
scraps fall into the air oil tank
 Inspect and clean the air oil tank for rust and dirt.
 Stick the new gaskets on to the separator element one
on either side.
 Replace the new separator element into the air oil tank,
taking care not to dent it against the tank opening.
 Reposition the Top plate and assemble it by using
fasteners. Torque: 120 N-m (88.5 lb-ft).
 Reconnect all piping.
 Clean the return oil strainer before restarting the
machine..
6.1.3.1 Oil top up & oil change over
Proper compressor maintenance and operation is crucial
for the lubricant to function properly and last till its
estimated rated oil hours. The oil product shelf life is of
minimum 3 years and maximum 5 years. Products should
be kept properly sealed in the original container. Once the
seal is broken, the above stated life span of the product is
no longer applicable. Products should be stored in proper
storage warehouse that is away from direct sunlight and is
not exposed to weather elements like rain, typhoon and
snow storms. The products should also be stored away
from any heat source, high humidity and moisture areas.
If drums are stacked on ground level, they should all be
stacked horizontally with the bung openings arranged at
the 3 and 9 o’clock position.
ELGi recommends that once the seal is broken, all
products be used immediately. ELGi does not encourage
reuse or recycling of any leftover fluids due to
contamination hazard. ELGi will not warrant the quality of
the product once the original seal is broken. Also ensure
that the oils are not mixed up between brands and types.
Please refer Material Safety Data Sheet (MSDS) for oil spill
handling and disposal procedures.
Pre work
 Switch off the compressor and disconnect power supply
to the compressor.
 Close the discharge end ball valve.
 Release air oil tank pressure and allow the tank to cool
for a few minutes.
Requirements
 New oil, flushing fluid (if needed)
Maintenance
Step 1: Draining
a. Remove drain plug from the bottom of the separator
tank and drain out all oil. Drain oil while the compressor
is warm.
b. Remove the pipe and drain plug from bottom of oil
cooler. Then completely drain.
c. Disconnect all oil pipe work which could trap oil and
drain completely.
d. Drain oil from the airend discharge pipe after
dismantling it.
e. Drain oil from the airend by hand rotation.
Step 2: Flushing (Only for oil change over)
Check the air-oil seperator differential pressure.
To flush clean/non-varnished machines, using:

TANK
The air-oil separator tank is tested according to standards.
Regularly have inspections performed in conformity with
local regulations.
NOTE
NOTE
 The compressor is originally filled with a particular oil, if
you want to change over to other types of oil, perform
steps 1, 2 and 3.
 But if you want to change the oil but continue with the
same kind (same brand & type) perform steps 1 and 3
only.
 Ensure that you drain at least 90% of oil capacity of the
compressor; if not the residual oil can contaminate new
oil.
 Ensure no oil spills on anti-vibration mount during
maintenance.
