Grade 9 Coalescing Separator/Filter
Once compressed air is cooled thermally, the condensed moisture must
be effectively removed. A poorly designed separator can allow moisture
to re-entrain itself into the compressed air system. It is particularly
challenging to consistently remove moisture at lower celocities (lower
loads). The HF Series Grade 9 Separator/Filter effectively solves these
challenges by utilizing two stages of filtration to remove bulk liquid
and solid particulates to 3 micron in size.
- 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 in size

The integrated HF Series
Grade 5 Coalescing Oil Removal Filter
Space and time-savings can be achieved by integrating an oil removal
coalescing filter into larger sized hankison refrigerated dryers. Instead
of having a separate filter vessel and piping installed outside of the
dryer...simply integrate it into the refrigerated dryer. This concept
is what we call an "Air Treatment Station" The HF Series Grade
5 high efficiency oil removal filter effectively uses two stages of filtration
to remove oil aerosols to .0008 ppm (0.01 mg/m³) abd sikud oartucykates
ti 0.01 micron in size
- First stage - multiple layers of fiber media and media screen remove
larger particles, pre-filtering the air for the second stage
- Second stage - multiple layers if bonded, blended fiber media for
fine coalescence captures fine oil aerosols and solid particles

3. Refrigerant Technology
Hankison selects the HFC refrigerants R-134a and R-404s for the HPRplus
and HES Series dryers, designed for industrial applications, based upon
the following criteria:
- Environmentally-friendly HFC refrigerants which comply with the montreal
Protocol of 1989
- Energy efficient at "medium" evaporator temperatures of
35°F, Below 3hp, R-134s with reciprocating compressors provide optimal
performance. At 3 hp and above, scroll and digital scroll compressors
utilizing R-404a provide the optimum pay-back depending upon the user's
air demand profile
