Compressed air filter element SHANGHAI HOLYSUN MACHINERY TECHNOLOGY
5 grades of element:
HF9 Separator filter
Precision 3 um (5ppm max. remaining oil content)
*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
HF7 Air line filter
Precision 1 um (1.0 ppm max. remaining oil content)
Corrosion resistant inner and outer cores
*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
HF5 High efficiency oil removal filter
Precision 0.01 um (0.01 ppm max. remaining oil content)
Corrosion resistant inner and outer cores
*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
HF3 Ultra high efficiency oil removal filter
Precision 0.01 um (0.001 ppm max. remaining oil content)
Corrosion resistant inner and outer cores
*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
HF1 Oil vapor removal filter
Activated carbon; Precision 0.01 um (0.003 ppm max. remaining oil content)
*Corrosion resistant inner and outer cores
*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
