ABSTRACT:
A portable air conditioner drier and chemical additive system feeder particularly useful for home and auto air conditioning systems. The unit is an in-line filter/drier with an input flexible line section and an output flexible line section connectable from a system high pressure fitting to the refrigerant system suction side valve fitting so that a portion of the system pumps high pressure gas output through the filter/drier for a short contaminant, moisture, and air removal running period of time generally to an extent of twenty to forty minutes. The filter/drier unit includes a screw top container that seals against leakage when threaded down normally containing a screen and filter material with a fill of desiccant particles cartridge which can be removed and replaced. With the filter desiccant cartridge removed and the container top open chemical additive fluids may be poured in with the unit attached to the low pressure fitting, the top threaded down again and the high pressure side reconnected to the system high pressure fitting or to a refrigerant material supply can to force flow the chemical additive fluids to the air conditioning system. A high pressure fitting adapter is used on the input flexible line section for connection to a system high pressure valve fitting of some systems.
