2 A blend of HFC refrigerants r -32, R-125, and R-134a (30 / 40 / 40 wt%) Application: An alternative to R-22 and R-404A in low and medium temperature refrigeration applications. Performance: There is a slight decrease in capacity and efficiency compared to R-22; however, R-407F can be used in essentially the same equipment to perform the same job. Lubricant: New systems built with R-407F must have POE lubricants, and retrofitted R-22 systems would need the residual oil flushed with POE. R-407F R-407F Available in the following sizes: 20R407 FRT 9 Kg RETURNABLE CYLINDER 44R407 FRT 20 Kg RETURNABLE CYLINDER 100R407 FRT 46 Kg RETURNABLE CYLINDER 1587R407 FRT 720 Kg RETURNABLE DRUM 25R407FN Kg DISPOSABLE DOT CYLINDER (EXPORT ONLY) _____ refrigerant Reference Guide Supplementary Edition National Refrigerants, Ltd.
