Precision Filters

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, Oil vapor removal 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—a 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 removes the remaining oil vapor
Multiple layers of fine media prevent particle migration
Outer coated, closed cell foam sleeve prevents fiber migration
Designed for 1000 hour life at rated conditions.
