I recently purchased a Paasche H-series kit from Amazon as I wanted to get a quality air brush. I was surprised at all the confusion around how to hook up the H to a standard shop air system and want to clarify matters.
Now the set comes with the airbrush, tips, bottles and an airline. The airline is the key – on the end that connects to the airbrush, it is 1/8″. The other is 1/4″ female. just take 1/4″ air fitting with male thread, apply several layers of PTFE tape to the thread and then screw on the hose and tighten – done. That’s it.
The red assembly above the plug is a cheap generic inline disposable filter. I simply have quick connects to make it easy to move my airbrush around to where I need to work in my shop. I run a high-end filter system in my shop and still put a screw in filter just before the air brush’s air line just to play it safe. If you run your air brush off your home compressor, you definitely need to do this and the more contaminated your air is, the faster the filter will foul out. If you have any questions about the quality of your air, shoot a blast at a test mirror and see what all spatters on it – you’re liable to see a ton of goop if you are not filtering out water and/or have a lubricator in the line.
If you do have a ton of contaminants and plan to airbrush a lot, then invest in a good filtering system. There are tons of them out there. At a minimum, considering really good disposable filters such as a Motor Guard M30 for 1/4″ lines. Worst case, just make sure you have the disposable filters installed and change them regularly. If you are still getting water and other junk when you spray, then decide how to either filter your lines or buy a dedicated airbrush compressor. For me, it was a no brainer given the air system I already have and the disposable filter is there “just in case”.
At any rate, this is a great airbrush. Having trashed numerous Harbor Freight airbrushes over the years, this is a wonderful step up. I hope this helps.
