However, for steady work at 100 psi or below, this air filter is excellent.

It is best to install a water separator in front of this air filter to trap as much water and oil as possible before it enters the air filter. This, of course, saves you needing to change the paper filter in this air filter all the time. With good separators in the line before this air filter, the paper filter can last over a year without the need to change it.

PneumaticPlus SAU4030M-N04DG-MEP

Key Specifications

plasma cutter filter
  • Mount – ½ NPT
  • Country Manufactured - Korea
  • How does it drain – Auto drains
  • Filtration rating – 0.3 micron
  • Max Supply pressure: 250 psi
  • What does it filter out: pipe scale, dirt, moisture, rust, and oil

This separator works brilliantly. It is excellent to use with any airlines or plasma cutters and would suit a medium-sized shop if using it with air tools. If you are, it is best used with at least 25ft between the compressor and the unit. This gives enough time for the copper piping to cool down the air and allows the water to form into large droplets so that this system can filter them out.

The automatic drains on this system work perfectly and makes this unit far easier to maintain. Just set up some plastic tubing on the outlet that feeds into a container and dispose of the water whenever needed. This is an excellent, hassle-free air filter for plasma cutters and air tools.

Pros
  • Well built
  • Easy to install and hassle-free to use
  • Excellent after-sales service
  • 1 year manufacturer warranty
Cons
  • Some leaks (maybe user error)
  • Expensive
