R22 Retrofit Gas

Westron R-407C is a zeotropic HFC refrigerant blend consisting of R-32, R-125, and R-134a. It is primarily designed as a non-ozone-depleting replacement for R-22 in positive displacement equipment such as new or existing residential and commercial air conditioners and non-flooded evaporator chillers. It is a popular “retrofit” gas for systems originally designed for R-22.
