Hey everyone,

I’m currently working on improving our workshop's air system setup, and I’ve been doing a lot of research into more reliable compressed air dryers, filters, and nitrogen generators—especially for automotive use like:

Spray painting (where dry, clean air is essential)

Pneumatic tools (avoiding moisture damage)

Tire inflation with nitrogen (for stability and longer pressure retention)

General shop air system upgrades

I recently found this site that seems to specialize in industrial air treatment solutions, including refrigerated and desiccant dryers, filters, and nitrogen generators:

Has anyone here used on-site nitrogen generators in an auto shop setting? Curious if the long-term cost savings really stack up vs. bottled nitrogen. Also interested in best practices for keeping shop air dry and oil-free—what kind of dryers or filters are you using?

Would love to hear what setups have worked best for your garage or shop!
