    CB 200 65# bone dry co2 tank & mbk 6

    I am now in possession of a 65 lb tank of bone dry co2

    That means by using a Rehvac MBK 6 in concert with my 65 lb tank, I will have more purge gas in my 2 1/2 lb MBK 6 than three regular nitrogen tanks.

    My total cost on 65 lbs of Bone Dry Co2 is 59 bucks.

    I tried to get a pic of the CO2 tank but I have a crummy camera on my phone.

    If more government is the answer, then it's a really stupid question.

    How much did that rig set you back?
    I'm still debating moving up to that 2.5# bottle from my 1.25# one.

    You are a little off on your estimate of the volume of gas from 2.5# of liquid CO2.
    According to REHVAC it is equivalent to 22 cubic feet, where a standard size N2 tank from an AC supplier is typically 40 cubic feet.
    Still, hauling a CO2 rig that weighs 7 pounds, including regulator, hoses, and carry strap, is a lit nicer than hauling a heavy ass N2 bottle up onto a roof.

    Look near the bottom of the page I posted a link for.
    "CO2- 2.5 lbs by weight yields 22 cubic ft."

    Eh, gotta proof read better.
    Here is what you get with with Nitro and CO in M9 tanK:
    Key Specs
    M9 CYLINDER CYLINDER CAPACITY REGULATOR HEIGHT WEIGHT
    Service Pressure 2015 psi Nitrogen- 1800 psi yields 9 cubic ft. CO2- 2.5 lbs by weight yields 22 cubic ft. 0-250 psi Adjustable MAX inlet Pressure 3000 psi 16"



    My point was Supposed to be the M9 Tank holds almost three times as much co2 vapor than nitrogen. Can do twice the amount of systems than nitro off the M9.

    What do you mean by liquid blast? Not liquid co2 I hope, regulators don't like that very much.

    And the sixty five lb tank cost me $59 to fill.

    How much does a field nitro tank cost to fill a 20 or 40cu ft-er and how heavy is it?

    This has it beat ten ways from Sunday.

    Clover must own stock in Dry Co2 manufactures.
