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. 2.Why remove moisture? Moisture drives acid formation, corrosion, and freeze-ups; ProDry converts it to oil. 3.How does it make air colder? Air Enhancer's polar molecule improves heat transfer by removing oil sludge on internal metal surfaces. 4.Is it compatible with my oil? Yes—mineral & synthetic. 5.Any safety notes? It's a flammable compressed gas; follow SDS and use away from heat/sparks.
