OPERATION
DOES EXPEL COST ANYTHING TO OPERATE?
Th e simple answer is NO. Th ere are no power requirements, and no consumable related costs associated with
the EXPEL unit so the only cost involved is for the initial unit purchase.
HOW DOES EXPEL WORK?
Th e internal Expel fi lter works by creating an impacting turbulent air path thus coalescing any liquids and
solids present in the compressed air line during the fi rst stage of fi ltration. As part of this initial phase Expel
removes 96% of all contamination while during the second stage the internal Unitary Vertical Body (UVB)
polishes the compressed air still further thus removing the fi nal 4% before exiting the fi lter air outlet.
Th e fi lter is manufactured from a strong polymer material, so it never needs replacing – ever. However, if you
have particularly dirty air lines then we would recommend that you simply dismantle and clean the internal
elements of the unit when necessary. Th e internal element does not need replacing.
WHAT IS THE INDICATOR FOR ON THE TOP OF THE EXPEL UNIT?
Th e indicator on the top of the unit is to provide a visual warning that the unit is under pressure. Once the
system is pressurized, the indicator will turn RED. Th e locking mechanism within the unit will prevent the unit
being opened when under pressure.
DRAINING
HOW DO I DRAIN THE EXPEL UNIT?
Th e EXPEL 30 unit comes equipped with an Automatic Float Drain. Th is fl oat drain is designed to discharge
liquids and particulates extracted from your compressed air system. Th e Auto Float Drain is screwed directly
to the base of the EXPEL unit and has an operation pressure up to 232 psi. A 6 mm diameter plastic tube can
be connected to the base of the drain to control the fl ow of the discharge fl uid into a suitable container for
disposal. Th e Automatic Float Drain can be easily dismantled for servicing and cleaning if required.
