R-407C
Technical overview
R407C refrigerant for compatible air conditioning applications
R407C is a zeotropic HFC blend used in compatible air conditioning and selected refrigeration systems. It can also be considered for some R22 conversions when the equipment and conversion procedure specifically permit it. The blend has temperature glide, so correct service information is important when evaluating system performance.

Service considerations
Because this is a zeotropic blend, service procedures must account for its composition and temperature glide. Equipment-specific instructions take priority over general replacement claims or comparisons.
Compatibility & handlingR407C is not a universal drop-in replacement for R22. A conversion may require lubricant or component changes. Do not mix the two refrigerants.
