Sub-Micronic Air Filter Kit for Plasma Cutter

AT1000 Sub-Micronic Air Filter for Plasma Cutter

Cleaner air, longer consumable life, better cuts.

The AT1000 Sub-Micronic Filter is designed specifically to solve one of the biggest problems in plasma cutting: contaminated air. Moisture, oil aerosols, and particulates from your compressor can cause sputtering, shorten electrode and nozzle life, and even damage your torch. The AT1000 stops these issues before they reach your machine.

By filtering down to 0.01 microns, the AT1000 delivers clean, dry, oil-free air that dramatically improves cut quality and extends torch life. With proper filtration in place, you’ll see smoother cuts, longer-lasting consumables, and less downtime for torch maintenance.

The AT1000 is manufactured in Italy to the highest possible quality standard.
