FREQUENTLY ASKED QUESTIONS
EFFICIENCY
WHAT CLASS OF AIR QUALITY DOES EXPEL PROVIDE?
EXPEL is designed and tested in accordance with the strict criteria of ISO12500, which is the validated
performance criteria specifi cally outlined for compressed air fi lters.
Previously, ISO8573 was the defi ned standard for compressed air quality, however this related to the air quality
of the system in its entirety, and was not component specifi c. ISO12500 is the further refi ned ISO test, which
is component specifi c.
EXPEL complies with
• ISO12500-1:2009 (Oil Aerosols)
•
ISO12500-3:2009
(Particulates)
•
ISO12500-4:2009
(Water)
DOES EXPEL REMOVE SOLID PARTICULATES AS WELL AS LIQUID WATER AND OIL EMULSION
FLUIDS?
Yes, the EXPEL is designed and tested in accordance with ISO12500, and will remove 99.999% of all solid
particulates down to 1 micron in size along with all liquid water and emulsion fl uids (oil / water mix.)
WHAT IS THE PRESSURE DROP ACROSS THE FILTER?
Th e maximum pressure drop across the EXPEL 30 is 0.1 bar (1.45 PSI). Unlike conventional fi lters, the EXPEL
does not retain the particulates it removes, so the pressure drop does not increase over time, saving energy
costs and improving overall system performance.
