Freon™ M099


The Alternative to R-22

Freon™ M099 is the closest match to R-22 operating pressures and mass flow rates when compared to other “no-oil change” replacements. The use of MO99 will minimize system component changes.

Freon™ MO99

  • Meets regulatory requirements
  • Closest capacity to R-22 with comparable energy efficiency
  • Best match to R-22 operating pressures
  • Extends life of existing equipment
