will emerge from the holes, indicating their locations. In
case of damages replace the filter element
Inspect all rubber sealing and their contact surfaces of
the housing. Faulty rubber sealing must be replaced
immediately.
Return the dust ejector back in correct (bottom)
position.
Return the filter element back in position, assemble the
filter housing cap such that the dust ejector settles in
bottom position, and lock the assembly using the
mounting clips.
Inspect and tighten all air inlet connections prior to
resuming operation (if necessary).
Reset the air filter clog indicator.
If a clean element is to be stored for later use, it must
be stored in a clean container.
6.1.2.3 Air oil separator
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
Strap wrench, new separator element, clean cloth.
Maintenance
Disassembly of the existing separator:
Hold the separator outer shell by the removed strap
wrench and rotate it counter clockwise, until it
completely unscrews.
Ensure the hex adapter stays in the separator head
during disassembly.
Once the recommended life is over, replace it with a
new element.
Assembly of a new separator:
Ensure the O-ring of the separator is damage free.
Clean the O-ring-seating surface with a clean cloth.
Apply a thin film of compressor oil on the mating
surface of the O-ring.
Return the separator to its original position and rotate it
by hand clockwise.
Ensure no oil leaks from the mating surface.
In case of leakage, check the O-ring.
After tightening by hand, rotate it further for one and a
half times.
6.1.2.4 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no longer applicable.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)
The air-oil separator tank is tested according to standards.
Regularly have inspections performed in conformity with
local regulations.
