Hypertherm128647 Eliminizer Air Filtration Kit with 1-Micron Filter and Auto-Drain Moisture Separator

Absolutely way to much money for what it is

If you want to maximize the usefulness of your plasma cutter and ensure it lasts a long time, you must provide clean and dry air from your compressor. It is a small price to pay when protecting a piece of equipment that costs $2,300.

This filter is NOT made by Hypertherm, but by Reading Technologies. The first time I used it I found it leaked air from the top of the flow indicator (with the green or red bubble). Like others, I was upset that a $200 filter would fail the first time and started to order the replacement Blanking Cap (#N32-95-020), but wanted to take one more good look. I removed the black top (with 2 screws) and noticed two SMALL brown O-rings that are supposed to seal the air as it goes through the flow indicator (bubble on top). One of the O-rings was pinched, but not torn. Using a small pick I removed both O-rings, let them regain their shape, lubricated it with my spit (not oil or WD-40!), then carefully reinstalled the top flow indicator making sure it seated gently through the O-rings without pinching or distorting them. Plugged in the air hose and NO LEAKS! Try this before you gripe out the seller, toss the filter, or order the blanking cap. It worked for me, and hopefully it will work for you.

I could have used a cheaper filter but I had bought a more expensive brand of plasma cutter so paid extra for the protection a week later found the same one in one of my tool boxes

Very good products, I'm well pleased.
