Internal Design

Internally, suction line lter driers employ the

same types of elements as liquid line units. One

is the core type, in which the lter drier consists of

a rigid, cylindrical, porous core that may perform

both the lter and drier functions, or be used in

combination with a separate accordion-type lter

element.

The core type lter drier is available either in a

hermetically sealed conguration or in take-apart

designs with a replaceable element.

The latest advancement is the bead-type unit,

in which the desiccant is compacted into the shell.

This design offers several advantages over older

types, including lower pressure drop, more desic-

cant surface area, and greater capacity.

Application Tips

Using a liquid line lter drier as a suction line

lter drier is not recommended. A suction line lter

drier should provide for greater capacity than a

liquid line unit, for better compressor protection

and for less pressure drop. Two access valves

are required to measure pressure drop across the

suction line lter drier.
