MAXREF R-410A is a widely used high-performance Hydrofluorocarbon (HFC) refrigerant. It is the industry standard for new residential and commercial air conditioning and heat pump systems, having been the primary replacement for the phased-out R-22 (Freon). The 9.4 kg cylinder size is a common disposable format for HVAC technicians performing system installations, recharges, and repairs on R-410A compatible equipment.
