R404a is a hydrofluorocarbon (HFC) refrigerant gas blend commonly used in commercial refrigeration and air conditioning systems as a replacement for older refrigerants that contribute to ozone depletion.

R404a is a hydrofluorocarbon (HFC) refrigerant gas blend that is commonly used in commercial refrigeration and air conditioning systems. It is composed of three different refrigerants: R125, R143a, and R134a. R404a was introduced as a replacement for older refrigerants, such as R22 and R502, which were found to contribute to ozone depletion. While R404a has a higher Global Warming Potential (GWP) than some other refrigerants, it is still considered to be an environmentally friendly alternative. It is a colorless, odorless gas that is non-toxic and non-flammable. R404a is widely used in supermarkets, refrigerated trucks, and other commercial applications due to its efficient performance and safety.
