R404A is a high-performance HFC blend consisting of R125 (44%) / R143a (52%) / R134a (4%), engineered for consistent low-temperature refrigeration. It has a boiling point of -51.7°F (-46.5°C) and offers excellent capacity retention in freezer and transport refrigeration applications. R404A operates at higher pressures than R22 and uses POE oil for lubrication. It has a very high GWP of ~3,922 but zero ODP, and is classified as A1 (non-flammable, low toxicity). R404A is known for its stable glide characteristics (very low temperature glide of ~0.5°F), making it perform similarly to a near-azeotropic refrigerant in real-world systems.
