DOES THE EXPEL ‘CONSUME’ COMPRESSED AIR?
Th e EXPEL does not ‘consume’ any of the air that a compressor produces. Th is ‘volume’ or ‘fl ow’ of air passes
directly through the Expel unit.
Th is means that if the air fl ow is 100L/min entering the EXPEL, it will be 100 L/Min exiting the Expel.
I HAVE INSTALLED MY EXPEL UNIT AND AM EXPERIENCING A HIGHER THAN STATED PRESSURE
DROP. WHY IS THIS?
Th e maximum pressure drops you should experience from a correctly installed EXPEL unit is 0.1 bar (1.45 psi).
If you are experiencing higher pressure drops than this after installing the EXPEL, undertake the following
actions to help identify the cause:
1. Is the unit installed in the correct orientation? On the top of the unit are directional fl ow arrows. Th ese need
to be facing away from the compressor, and towards the end of the air line.
2. Is there a blockage within the unit? Th e unit will need to be disassembled and inspected for a blockage.
I HAVE INSTALLED MY EXPEL UNIT AND AM EXPERIENCING A REDUCTION IN AIR FLOW, WHY IS
THIS?
If you are experiencing a reduction in ‘fl ow’ this would suggest that some of the produced air is being consumed
or lost elsewhere in the system. Th is is unlikely to be caused by the EXPEL if it has been installed correctly. We
suggest checking to see:
1. Is there an autodrain unit or manual drain tap fi xed to the base of the EXPEL? – Air should not be fl owing
freely out of the base of the Expel unit.
2. Is there air any leaking from the connections in / out of the EXPEL?
3. Is there any air leakage from the base of the EXPEL?
4. Is the drain tap / Autodrain continually leaking air?
If any of these are being experienced, please refer to the installation manual provided within your EXPEL’s box.
