A2L Compatibility

Fieldpiece Has You Covered.


Defining A2L

The HVACR industry is making the transition to more environmentally friendly (lower GWP) refrigerants. With this transition, HFCs are being
phased down and there has been a growing acceptance of the use of A2L refrigerants due to their lower flammability and toxicity.


A2L Refrigerant Replacement

Just like A1 refrigerants, some A2L refrigerants are blends and some are pure. Here are a few A2L refrigerants and what HFCs refrigerants they replace. Please refer to flammable refrigerant safety guides, regional codes and legislation for more information about handling these refrigerants.
