I need a new compressed air tank, the old one rusted out. I bought a 5 gallon tank at Tractor Supply, had it filled, and when I went to use it a few days later, no air. Returned to store.

Looked at Home Depot, they carry compressors but not just a tank. Walmart sells a 7 gallon Briggs & Stratton tank, but I would rather have the smaller, lighter 5 gallon size.

Suggestions? Thanks!

Any hvac or refrigeration contractor will have tons of old empty freon tanks laying around. They look similar to a propane grill tank but use 5/16" acme-type fittings and are meant for holding pressure. An adapter fitting from 5/16" acme to a hose barb for regular compressed air hose can be had for a couple dollars on amazon.

Add a psi gauge and regulator and there you have it, I have this same setup. Mine also uses a schrader style fill valve
