Liquid Line Filter-Drier

Liquid Line Filter-Drier

A loquid line filter-drier must be used on all field installed systems, and on all systems opened in the field for service. Filter-driers are highly recommended forall systems, but are not mandatory on factory assembled and charged units where careful dehydration and evacuation is possible during manufacture. Precharged systems with quick connect fittings having a rupture disc are considered to be the equivalent of factory charged systems.

Moisture can be a factor in many forms of system damage, and the reduction of moisture to an acceptable level van greatly extend compressor life and slow down harmful reactions. The dessicant used must be capable of removing moisture to a low end point and further should be of a type which can remove a reasonable quantity of acid. It is most important that the filter-drier be equipped with an excellent filter to prevent circulation of carbon and foreing particles.
