Air tank

So, my buddy picked up a sweet Viair compressor for me off of an old ambulance for free. Now my question is, how to build/buy an air tank on the cheap.

I was thinking of PVC since, it's a. cheap, b. strong, and c. meant to last forever. Schedule 40 4" is rated to 220 psi, so a regulator set to 100 psi, should be sufficient. And, yes, I've read all the warnings about not using it for this purpose, so I'm well aware.

So with that out of the way, has anyone successfully done this? And mind you, the only thing this will be used for is inflating bike tires, matresses, etc. I won't be using this for tires, etc.

 

Will this be a portable tank? Can’t see it being much use for such a small volume of air as needed for an air mattress or bike tire if the compressor itself is within reach.

Just to throw it out there, in case you missed it, pressure cycling pvc is going to weaken it substantially over time.

Edit: never done this, to answer your question.

 

Absolutely NEVER use PVC as an air tank. That is a literal ticking time bomb. I’ve seen too many PVC pipes explode under air pressure. PVC as a water tank? Sure, pressurized water doesn’t have nearly as much energy as pressurized air. Use steel

 

A real air tank is as cheap as $30.

 

Try this. I have a full air setup in my Jeep and works great.

In terms of tanks.... NEVER use PVC.
There are plenty of 'kits' online to buy tanks that are already prepped and ready to hook up - depending on the size you want / need. Or - if you have access to some old CO2 tanks, or old tanks from scuba shops, etc..... you can retrofit those.
We had a CO2 tank cut down to size - caps rewelded - bungs cut & welded in. This was mounted in our jeep.

 

Ok, I'll pass on the PVC. Turns out I never needed to post this anyway. My buddy has an air tank to go with it... Problem solved.
