The Sun KoolKare Blizzard HFO from Snap-on is a top-of-the-range car air conditioning machine that allows you to recycle HFO1234yf refrigerant.

KoolKare Blizzard HFO


The Sun Blizzard HFO car air conditioning machine has all the same features as the Sun Blizzard PRO but instead services vehicles using HFO1234yf gas.


* Please note that the image is shown with the optional KoolKlean purification system, which does not come as standard with the Blizzard HFO.

  • User friendly interface: The 5’’ high resolution colour display guides you through the air conditioning procedure
  • Extensive database: A comprehensive and fully updateable built-in vehicle database with the ability to add new vehicles, ensuring you can service all your customers’ vehicles
  • Refrigerant service archive: Unit automatically tracks and logs refrigerant usage in relation to recovery, system filling and bottle filling
  • Refillable hermetically sealed bottles: Prevent oil and dye bottle contamination and ensure a quality air conditioning service - the AC oil is hygroscopic and our system prevents moisture ingress
  • 100mm analogue gauges: Provides quick and easy referencing
  • Integrated printer provides you with the ability to produce your test results: Doubles as a customer receipt and tangible proof of maintenance
  • 3m long hoses (6m option available): Allows for the procedure to be carried out while the vehicle is raised on a lift
  • Optional KoolKlean purification system: Don’t just mask the problem, eliminate the root cause by eliminating the bacteria that causes the bad odour and leave the car smelling fresh - this is a great additional sales opportunity for your workshop
  • Multitask operations option: Carry out the KoolKlean purification at the same time as the AC recovery so you can complete the AC service while removing bad odours
  • Visual indicator system: A colour coded light system is included so that even at the other end of your garage a simple glance will let you know what is happening
  • HD11 oil servicing: The HFO can be used to service HD11 oil (Hybrid cars) - hybrid functionality is becoming commonplace and standard machines cannot service these vehicles
  • Automatic system: Saves time and increases workshop productivity as the process can be started left to run with no further user input


  • Accessory Kit
  • Flushing Kit
  • Nitrogen Leak Check Kit
  • FGAS Training
  • KoolKlean purification system
Please wait while we gather your results.
