A1 HFC refrigerant blend
R-407A is a blend of HFC R-32, R-125 and R-134a. In terms of capacity and efficiency it is similar, and can therefore represent a possible alternative, to the old R-22 refrigerant, although it is not a direct drop-in retrofit product. It is not an ozone-based gas and has a GWP lower than that of R-404A.
