The PAC-SPRFCS Refrigerant Filter/Cleaning System is a suction line filter assembly for the enhancement of refrigerant quality. Minimizing potential contaminant introduction during the installation of field piping or compressor change outs will result in less system damage and compressor failure. CITY MULTI® outdoor units are equipped with strainers but cannot protect from finer particles and debris not properly removed from field piping or other sources prior to installation. The refrigerant filter/cleaning system will assist in the removal of this debris resulting in less failure and improved system operation over the life of the system. The PAC-SPRFCS System comes with a suction line filter of higher filtration efficiency that ensures such foreign debris is not migrating to the compressor or other critical parts after startup.
