OIL FILTERS AND OIL FILTER-DRIERS
The function of an Oil Filter is to remove system debris from the
refrigerant oil to protect the Compressor and other Oil Management
System components from damage. In addition to removing debris,
the Oil Filter-Drier also removes moisture from the refrigerant oil.
Applications
Henry Technologies' Oil Filters and Oil Filter-Driers can be used in both Low
and High Pressure Oil Management Systems. The unique drying features of
the S-4005 model are particularly suited for systems using POE oil. This type
of oil is more hydroscopic than mineral oil. This means that POE oil absorbs
moisture at a much higher rate. Moisture in a refrigeration system can
produce problems and/or harmful conditions. One S-4004 or S-4005 model
can be fitted in the oil return line between the Oil Separator and Oil
Reservoir, instead of fitting one Oil Strainer per Oil Level Regulator. These
models will also remove more debris than traditional oil strainers. Henry
Technologies' Oil Filters and Oil Filter-Driers are suitable for use with HFC
and HCFC refrigerants and their associated oils, as well as other industrial
fluids non-corrosive to steel and copper.

1. The Oil Filters and Oil Filter-Driers must be installed in accordance with
the flow direction arrow.
2. Units should be replaced after a 15 PSI (1 Bar) pressure drop has been
detected. It is recommended to install valves on either side of the filter
to ease replacement.
3. For Low Pressure Oil Management Systems, Oil Filters and Oil FilterDriers should be located between the Oil Separator and Oil Reservoir
not between the Oil Reservoir and the Oil Level Regulator.
