Looking for used #2500 cylinders

[bmiller59]

We have a HM prop about to go on line. It will use quite a bit of air. I don't want to cycle our frontline 4.5 cylinders, instead would like to get some 2.5s and dedicate them to the prop. Anybody have a source for used (cheap) cylinders?
Thanks, Bill.

Sorry, I can't help you with the air bottles. But......

What is a HM prop?

[bmiller59]

Haz-Mat prop. Lot's of piping and valves and such. The system can be pressurized with water, air or both. Should be pretty cool.

We are getting rid of some low pressure survivair cylinders if you are interested I can get a price from my chief.

Check with the local SCBA guys. Most have a bunch of the old cylinders

Why would you want to mix cylinders? Just get a 4.5, that way you wont have to worry about the guy blowing his face off when he tries to refill that 2.2 with 4.5 pressure.

if you don't know the difference, you shouldn't be filling cylinders.

[ScareCrow57]

if you don't know the difference, you shouldn't be filling cylinders.

Boy!!! Ain't that the truth!!!

[jonnyirons2]

right, cause the guy who fills them up always knows what he is doing.

[MEAN15]

he does at our house.

I'll say it again - if he doesn't know the difference, he shouldn't be filling.

If you want to make something idiot-proof, sometimes you have to remove the idiot.

We are going another direction with the air supply. A small portable compressor will give us what we need and eliminate the need for regulators and switching cylinders. As for the local SCBA guys that's me. It's all 4.5 around here.
We did have a guy try to fill a low pressure that the PD has at the jail. When the burst disc blew, they all scattered. I wasn't on that day, we put a stop to filling other agencies cylinders, unless me or the other tech do it.

[MEAN15]

Yeah - blowing a disc is a real attention-getter. I'm glad you found a workable solution for your problem. Sorry I hijacked your thread.
