Questions about this item

How often should the filter element be replaced on the 228926 in-line air filter?

Replace the filter element when airflow drops noticeably or after the hours recommended in your plasma cutter manual, whichever comes first.

What is the first limit reached during extended cutting with the 228926 installed?

The 1/4 in NPT quick-disconnect fitting and filter housing set the maximum flow; pressure drop across the element becomes the limiting factor under sustained high-amperage cuts.
