What is R-407F?

R-407F is Honeywell's commercial refrigeration HFC blend with composition tuned for lower GWP than R-404A while maintaining or exceeding R-404A's capacity. The 30% R-32 content (higher than R-407C's 23% or R-407A's 20%) drives both the capacity and the pressure envelope toward R-404A's operating window.

R-407F sits between R-407A (GWP 2107) and R-407C (GWP 1774) in terms of GWP, while having the highest R-32 content of the R-407 family. The "Performax LT" branding emphasizes the low-temperature performance niche.

Where R-407F is used

  • Commercial refrigeration medium and low temperature
  • R-404A retrofit (lower GWP, similar capacity)
  • R-22 retrofit (commercial refrigeration applications)

Regulatory & phase-down status

R-407F's GWP of 1825 is above the EPA AIM Act 700 threshold for new equipment. For new commercial refrigeration installations the modern path is R-448A, R-449A, R-454C, R-455A, R-744, or R-290.

Service notes

POE oil required. Significant temperature glide (~5-6°F at typical operating pressures); TXV operation may require attention. Use the dew curve for superheat measurement.

R-407F is a zeotropic blend: at constant pressure it boils across a temperature range rather than at a single point. This affects EXV sizing, charge measurement, and superheat measurement. Use the dew curve for superheat, bubble curve for subcooling.

Phase-down timeline

No phase-down milestones documented for R-407F in this build. This may mean: (a) no regulatory phase-down currently published; (b) the refrigerant has local regulatory schedules not yet transcribed into the site dataset; or (c) it is a specialty refrigerant outside the main regulatory frameworks. For authoritative current status, consult the EPA AIM Act allocations (40 CFR Part 84), EU F-Gas Regulation 517/2014 + 2024/573, and the relevant national implementations of the Kigali Amendment.

Frequently asked

›How does R-407F compare to R-407C?

Higher capacity, higher pressures, slightly higher GWP. R-407F is 30/30/40 (more R-32, more R-125, less R-134a) vs R-407C's 23/25/52. The higher R-32 content gives R-407F better volumetric capacity, making it more suitable for commercial refrigeration where R-407C falls short.

›Why use R-407F instead of R-404A?

Lower GWP (1825 vs 3922) with similar capacity match for low-temperature commercial refrigeration. R-407F was Honeywell's intermediate-GWP option in the early 2010s before the very-low-GWP A2L blends (R-454C, R-455A) became broadly available. For new installations the modern A2L blends are preferred; for retrofit of existing R-404A systems where A1 non-flammable is critical, R-407F remains a meaningful GWP improvement.

›What lubricant does R-407F use?

POE oil. Mineral oil and alkylbenzene are not miscible.

›What is the normal operating pressure of R-407F?

Higher than R-407C across the envelope. At 25°F walk-in cooler evaporator with 95°F ambient, expect approximately 55-70 PSIG suction and 240-290 PSIG discharge. R-407F runs closer to R-404A pressures than R-407C does.

›Is R-407F still being sold?

Yes, by Honeywell, with continuing US distributor availability for the R-404A retrofit market. AIM Act phase-down constraints will reduce supply over time as virgin HFC production caps reduce overall HFC consumption.
