Restore the cold you expect from your R-1234yf A/C in one step. Arctic Air blends ProDry to convert harmful moisture into synthetic-oil and Air Enhancer to remove insulating oil film inside coils for better heat transfer. The result? Colder duct temps, reduced friction inside the compressor, and protection against acid-forming corrosion that shortens system life. Installs like refrigerant via the low-side 1234yf port using a 134a-style tap with a 134a→1234yf hose/adapter. For best results, add to systems that are not fully charged. Not refrigerant. Do not use in CO₂ or ammonia systems. Follow all safety instructions/SDS. Tech Specs Platform: R-1234yf mobile A/C Can size: 4 oz (aerosol); typically treats one passenger vehicle Use-restrictions: Not for CO₂ or ammonia systems; NOT refrigerant Charging port: Low-side with 134a→1234yf hose/tap (see kit option) FAQs 1.Is this a refrigerant? No. It's a booster/additive for R-1234yf systems. Enviro-Safe 2.Why remove moisture? Moisture drives acid formation, corrosion, and freeze-ups; ProDry converts it to oil. Enviro-Safe 3.How does it make air colder? Air Enhancer's polar molecule improves heat transfer by removing oil sludge on internal metal surfaces. Enviro-Safe 4.Is it compatible with my oil? Yes—mineral & synthetic. Enviro-Safe 5.Any safety notes? It's a flammable compressed gas; follow SDS and use away from heat/sparks. Enviro-Safe
