Bring back the chill in your vehicle's A/C system with Arctic Air for R1234yf Systems. This advanced formula is a powerful combination of two Enviro-Safe products packed into one easy-to-use aerosol can. Designed to fight moisture, reduce friction, and maximize cooling, it helps restore your A/C performance while extending system life. Each can is recommended for one vehicle application. It works as an A/C booster and drying agent, delivering colder duct temps and smoother operation. Moisture inside an A/C system can cause corrosion, freezing, or long-term damage — Arctic Air helps solve that by pulling moisture out while boosting overall efficiency. ✅ Compatible with any automotive refrigerant (except ammonia & CO₂ systems). ✅ Installs the same way as refrigerant — quick and simple. ✅ For 1234yf vehicles, you'll need the correct hose/gauge with a 134a top (available separately under part numbers: 3600, 3610, 3635, 3615). Important: This is not refrigerant and does not replace R1234yf. It's an additive/booster designed to enhance your A/C system's performance.
