EXPEL 30 FILTER & AUTO DRAIN SET
FREQUENTLY ASKED QUESTIONS
ABOUT EXPEL
WHAT IS EXPEL, AND WHAT DOES IT DO?
EXPEL is a unique, patent protected compressed air fi lter, and is designed to remove all (99.9999%) liquid
water, emulsion fl uids (oil & water mix) and solid particulates down to 1 micron from a compressed air line.
WHAT MAKES EXPEL DIFFERENT TO ANY OTHER COMPRESSED AIR FILTER?
Th e EXPEL is the worlds fi rst compressed air fi lter capable of removing such a high level of liquids and
solid particulates that can be taken apart, cleaned and reassembled. Typically, you would require at least 3
conventional compressed air fi lters to achieve the same air quality as 1 EXPEL unit.
DOES THE EXPEL 30 UNIT REQUIRE ELECTRICAL POWER OR MAINTENANCE?
No power source is required. If needed, the Automatic Float Drain can be easily dismantled for servicing and
cleaning.
WHAT SIZE IS THE UNIT?
As a guide, the physical size of the EXPEL 30 which is most commonly seen in workshop applications is 293mm
High x 80mm Diameter.
WHAT GRADE OF MATERIAL IS EXPEL MANUFACTURED FROM?
Th e external body and head of the EXPEL unit are manufactured from Grade 304 stainless steel. Th e internal
fi lter element is made from ABS polymer material.
HOW DOES EXPEL COMPARE TO OTHER CONVENTIONAL WATER SEPARATORS ON THE MARKET?
Conventional fi lters tend to remove water using the cyclonic method rather than the patented multi directional
vanes and clarifi cation chambers inside the EXPEL. Th ese vanes and chambers force the coalescence of all
water into tiny droplets which are then removed by the fi lter allowing a 99.9999% removal rate of the water,
and emulsion fl uids (oil & water mix)
Cyclonic separators experience notable drops in performance when the air velocity is irregular, and are
problematic with stop/start air fl ow unlike EXPEL, which reaches optimum performance within a fraction of a
second.
I ALREADY HAVE EXISTING COMPRESSED AIR FILTERS INSTALLED, BUT STILL SEE WATER. WILL
THE EXPEL HELP?
Yes, the EXPEL is designed to remove water, emulsion fl uids (oil/water mix) and particles down to 1 micron.
Conventional fi lter/regulators commonly perform at around 20 to 50 micron, much less than the EXPEL.
Th e EXPEL has signifi cantly better water removal performance than traditional fi lter/regulators. Most common
conventional compressed air water separators achieve less than 92% effi ciency compared with the EXPEL’s
99.9999%.
WHY IS THE EXPEL 30 UNIT MORE EFFICIENT THAN TYPES OF WATER SEPARATORS?
Conventional water separators rely on both a consistent fl ow and velocity to work effi ciently. Due to the unique,
patented technology within the EXPEL, it will perform to it’s maximum effi ciency regardless of the fl ow rates,
and even under pulsed stop/start conditions.
