Hypertherm's air filtration kit is a great way to protect & prolong the life of your plasma cutter. It comes ready to install with a 1-micron filter & attaches easily to the power supply using the pre-existing mounting holes. It features a top-side indicator that turns red when the filter element needs to be replaced.

This air filter works with All Hypertherm Units. This kit comes with a steel guard that only fits the Powermax 65 and 85. The proper kit for Powermax 105 and 125 units would be the 228890 kit.
