Air Tool Question

[Limited-Time]

Re: Air Tool Question

I know this is bringing up an old post but I've been thinking what if I bought a used air compressor and took off the motor and just used the tank as an add on to mine? would'nt that work to provide more cfm? Zet

For short term usage, yes. What you need a compressor head/motor combination that will produce more air at a given pressure than you are using.

It would. Try to find the biggest you possibly can and interconnect the two tanks with coper water pipe, schedule 80 pvc or almn pipe.

Never ever use PVC pipe for air. When a plastic pipe breaks, you have plastic shards flying around.

Hmm, never had a problem with it. You shouldn't have an issue it is kept within the specs.

Nope. You'll have an extra reserve for a short while but your total compressor run time will be the same as it has fill the tanks to begin with. So this will allow you to run a tool for longer bursts of time your total tool run time will be the same though.

Only the pump produces CFM the tanks just hold them.

There are no specs for a PVC Sch 80 pipe to carry air. Specs for PVC are for liquid only. The difference between a pipe bursting with air or water in it is that water doesn't compress like air does. When a pipe pursts that has air in it, the air expands rapidly sending little pieces of your pipe flying like shrapnel.

Or you can do what I did. Put quick disconnects on each tank and use a large-diameter, short piece of air hose to connect them. Also you could use black-iron if it's a permanent installation.

I agree, don't use PVC. Even if it will take the pressure, something might be dropped on it and break it. Then you have shrapnel.

Ayuh,......

Watch the Yard Sales,+ Estate Auctions.........


Propane Tanks are rated to 250psi,.....
And,....
If, or When they rot out, it's a tiny hole in the bottom that leaks.....
The chance of Catastrophic Failure is Extremely Slim.......
I have several set up for Air, depending on the job at hand,....
You can snap 1 in anywhere in the system to benefit from the Volume.....

Yep...if ya start with an old rusty tank, well..don't.
I've made many air tanks out old propane tanks..zero problem, and like Bondo sez...pin hole first, not a blow up..(gotta stop the wifes tale here now..wanna have some fun? Take a liter soda bottle. Super glue in after drilling out the cap, for a Schrader Valve..stuff it with 100lbs air...set it out in the yard, and nail it with a pellet gun...good 100 feet in the air if ya hit it right!...find the cap, and do it again new bottle!..or just stuff it with dry ice, cap, wait a few hours for the BOOM!)
That said the bigger the hose the better..(volume), and the more storage tanks in line, the better. I have a 5hp, 12 gallon tank on my presser. Shoves 7 cfm at around 90 psi. Works fine on my air tools, but ya gotta wait at times for the refill. Ya want power, well, ya gotta buy it...if it aint 6 foot tall sitting in the corner of the shop on 220...well...
PS...propane tanks will not "blow", the reason for concern is leaking fumes, that collect and blow the house to the ground when ya light up a smoke off a lighter...wondering why things smell funny..and don't worry moisture..just drain once in a while..(the quick disconnect..open to air), and P tanks are twice the thickness any regular air storage tanks...and they last YEARS..with no drain..
