Not All Tools Need Filtered Air

Not every tool in your shop would need filtered air. And for this reason, it is important that you have sources of filtered and non-filtered air in your shop. This will help reduce the number of filter cartridges that you make use of. If you are filling a tire on your truck with air, you would not want to be running that air through your cartridge as it is just a waste.

One easy way to do this is by mounting your air filter directly to your plasma cart and only use it with your plasma cutter. This is one preferred method. If you have a variety of tools that need filtered air like a paint sprayer, then what you can do is to simply split the air output right at the compressor and then install the filter on one side only. In doing this you can hook to your filter when it is needed. People that use this method typically like to also install a cut off valve before the filter just to make sure that it only sees air when they are using it.
