2.4 Assembling / Installing the Air Filter
 Screw the air filter assembly into the threaded hole in the front of the compressor by
hand.
NOTE : If an intake extension tube is to be used to relocate the air intake then the
extension tube will be screwed into the front of the compressor and the air
filter will be screwed into the extension tube (See section 2.7).
HINT : If extra tightening force is required, the air filter can be tightened by
disassembling the cover, removing the filter disk, and using an 8mm [5/16”]
hex key on the center of the port.
 The cover logo may be rotated by hand as desired.
2.5 Using an Air Filter Extension Tube (optional)
The air filters of the CKMTA were designed so that they could be relocated to a more
suitable location (if required) using an extension tube.
IMPORTANT :
The length and inside diameter of the extension tube can restrict the intake flow
and negatively affect the performance of the compressor. In severe cases this could
result in overheating and/or damage to compressor components. Use the following
chart to make sure that the extension tube will not restrict the intake flow.
 Measure the intended length of the extension tube along the path between the
compressor mounting location to where the air filter will be mounted.
 Consult the chart above for the recommended minimum inside diameter of the tube.
NOTE : If intending to join the two intakes into one extension tube then halve the
values in the 'Maximum Length of Tube' column above.
NOTE : ARB does not recommend connecting the compressor intake to the air
supply in a ‘snorkel’ or other part of the air ducting for engine aspiration.
However, if an extension tube is used to relocate the compressor intake to
the engine intake supply then it must be understood that the negative
pressure (vacuum) created by the engine when it is running will adversely
affect compressor performance.
NOTE : Do not run the tube through areas where it will be exposed to elevated
temperatures while the compressor is running as this will pre-heat the air
intake and reduce compressor performance.
