4.7 REMOVAL AND INSTALLATION, AIR DRYER FILTER ELEMENT

Note:

To be certain that the air dryer is functioning 

properly, the air reservoirs should regularly be 

checked for condensation. If more than the 

normal amount of water is drained off repeatedly, 

the air dryer element must be replaced. Under 

normal circumstances the element must be 

replaced at least once per year.

Removing air dryer filter element
1.

Vent the air dryer by allowing it to regenerate 

or by loosening the compressor line (1), so 

that the interior of the air dryer is 

depressurised.

2.

Remove the filter element by turning it anti-

clockwise using a filter strap spanner.

3.

Dispose of the drying element as if it were an 

oil filter.

4.

Clean the air dryer internally.

5.

Check the air dryer threaded connection (2) 

for damage and then lubricate it sparingly 

with grease.

Installing the air dryer filter element
1.

Lubricate the sealing ring of the new filter 

element sparingly with grease.

2.

Fit the filter element by manually tightening it 

until the sealing ring abuts. Then tighten the 

element by hand (approx. 1 turn).

3.

Fasten the compressor line (1).

4.

Pressurise the system and then check the air 

dryer for any air leaks.
