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 filter, and is designed to remove all (99.9999%) liquid
water, emulsion fluids (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?
e EXPEL is the worlds first compressed air filter 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 filters 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?
e external body and head of the EXPEL unit are manufactured from Grade 304 stainless steel. e internal
filter element is made from ABS polymer material.
HOW DOES EXPEL COMPARE TO OTHER CONVENTIONAL WATER SEPARATORS ON THE MARKET?
Conventional filters tend to remove water using the cyclonic method rather than the patented multi directional
vanes and clarification chambers inside the EXPEL. ese vanes and chambers force the coalescence of all
water into tiny droplets which are then removed by the filter allowing a 99.9999% removal rate of the water,
and emulsion fluids (oil & water mix)
Cyclonic separators experience notable drops in performance when the air velocity is irregular, and are
problematic with stop/start air flow 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 fluids (oil/water mix) and particles down to 1 micron.
Conventional filter/regulators commonly perform at around 20 to 50 micron, much less than the EXPEL.
e EXPEL has significantly better water removal performance than traditional filter/regulators. Most common
conventional compressed air water separators achieve less than 92% efficiency 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 flow and velocity to work efficiently. Due to the unique,
patented technology within the EXPEL, it will perform to it’s maximum efficiency regardless of the flow rates,
and even under pulsed stop/start conditions.
