It can be added to any compressor. They come in many different quality levels at different expense points. I'll link two different options.

Some include auto lube arrangements, to keep your air tools lubed. You do not want this since you don't want oil on your computer.

This one is basic and will do the job: https://www.amazon.com/dp/B0000CBINA/ref=cm_sw_r_cp_apa_i_PT3dFbXAZJY5D

If you were painting automobiles headed for high-end auctions it would be important that absolutely no moisture or oils ever at all got into your paint spray. You would use something more like this: https://www.amazon.com/dp/B016XIWMPI/ref=cm_sw_r_cp_apa_i_5W3dFbCCACVBX

anything like this that you buy will require you to take the hose attachment point off of your compressor, take that and the filter to hardware store, and buy the correct fittings to make it fit. It's not as intimidating or complicated as it sounds, pipe fittings are pretty easy.

depending on what compressor you get it might have a different size fitting on the output. That's why I can't just tell you what fitting you would need to make this fit your compressor.

hope that helps, I'm not the most knowledgeable but I'm happy to share what I do know.
