Mihama Refrigerant Gases Freon™/Opteon™ Freon R-407c

Freon R-407c

Freon™ 407C (R-407C) is a R-22 replacement primarily for air-conditioning. It’s a HFC blend that requires a POE lubricant.

R-407C is included in the U.S. EPA SNAP de-listing of HFCs that will no longer be acceptable in new equipment in certain end use applications in the Indian market.
