AK Flush


AK flush is designed for flushing refrigeration and air conditioning systems to remove contaminants reducing the potential of future system failures.

It is also ideal for system flushing when carrying out a full retrofit.


Initiate the flow from the highest point on the system. Allowing the product to be expelled into the supplied container(s), until the ejected solvent runs clear. Should a single treatment fail to run clear, repeat the process until the solvent leaving the system is clear.

If you are working in an enclosed space, we would recommend the use of a respiratory vapour mask.

You should also be mindful of the potential flammability of the product if in an enclosed space.

The above can be negated by working in a well-ventilated area.

Product Features & Benefits

  • The AK flush cylinder is pressurised to 10 bar with CO2 which pushes the solvent through the system, removing any residual oil and solid matter.
  • A 5kg AK flush pack is generally adequate to clean a system of up to 15kw (systems with long pipework runs and large diameter pipework may require a larger size of container).
  • The cost of waste destruction is included in the initial price.
  • AK flush is non-toxic and non-ozone depleting, but it can be flammable under certain conditions.
  • AK flush is non-corrosive to the materials normally used in the refrigeration and air conditioning industry.
