COMPRESSOR PROTECTIVE DEVICES

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.

Technical Specifications

Maximum working pressure = 450 PSI (31 Bar)

Allowable operating temperature = 14°F to +212°F (-10°C to +100°C)

Installation - Notes

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 Filter-

Driers should be located between the Oil Separator and Oil Reservoir

not between the Oil Reservoir and the Oil Level Regulator.

Materials of Construction

All pressure bearing components including shell, caps, and connection

fittings are made of carbon steel. The internal spring is made of steel and the

O-ring is made of synthetic rubber.
