1). Separator filter (HF9)
For bulk liquid removal plus a 3 micron coalescer (5ppm w/w maximum remaining oil content)
Two-stage filtration
* First stage: two stainless steel orifice tubes provide 10 micron mechanical separation
* Second stage: in-depth fiber media captures solid and liquid particles to 3 micron"
2). Air line filter (HF7)
For removal of liquid water and oil; removes solid particles to 1 micron (1.0 ppm w/w maximum remaining oil content)
Corrosion resistant inner and outer cores
Two-stage filtration
* First stage: captures larger particles with alternate layers of fiber media and media screen
* Second stage: coalesces aerosols and captures solid particles with multiple layers of epoxy bonded, blended fiber media.
3). High efficiency oil removal filter (HF5)
For coalescing fine water and oil aerosols; removes solid particles to 0.01 micron (0.01 ppm w/w maximum remaining oil content)
Corrosion resistant inner and outer cores
Two stage filtration
* First stage: multiple layers of bonded, blended fiber media for fine coalescence.
* Second stage: multiple layers of bonded, blended fiber media for fine coalescence.
Outer coated, closed cell foam sleeve.
4). Ultra high efficiency oil removal filter (HF3)
For coalescing ultra-fine oil aerosols; removes solid particles to 0.01 micron (0.001 ppm w/w maximum remaining oil content)
Corrosion resistant inner and outer cores
Two stage filtration
* First stage: coated, closed cell foam sleeve acts as pre-filter and flow disperser.
* Second stage: multiple layers of matrix blended fiber media for ultra-fine coalescence.
Outer coated, closed cell foam sleeve.
5). Activated carbon air filter (HF1)
For removal of oil and hydrocarbon vapors normally absorbable by activated carbon; removes solid particles to 0.01 micron (0.003 ppm w/w maximum remaining oil content)
Corrosion resistant inner and outer cores
Two stage filtration
* first stage: stabilized bed of finely divided carbon particles removes the majority of the oil vapor.
* Second stage: multiple layers of fiber media with bonded micro fine carbon particles remove the remaining oil vapor.
