About Catalina 80 cf Neutrally Buoyant Aluminum Tank w/ Pro Valve

Catalina's Neutrally Buoyant 80 cu ft (10.3 liter) Aluminum Cylinder has a working pressure of 3300 psi (228 bars) and is negatively buoyant when full -5.9 lbs (-2.68 kg) and is nearly neutral when empty -0.2 lbs (-0.09 kg). The advantage of a cylinder that is near neutral buoyancy at the end of a dive is that you can shed a pound or two from your weight belt or BCD pockets. Dimensionally the cylinder is the same as the standard 80 cu ft 3000 psi (11.1 liter) tank, but does not have the positive buoyancy of +4.1 lbs (+1.86 kg) when empty. The Neutrally Buoyant 80 cu ft (10.3 liter) cylinder has a 7.25" (18.4 cm) diameter and is 25.1" (63.8 cm) tall having the same diameter as a standard aluminum 80 yet, is slightly shorter than the standard 80.

Cylinder comes with a K Pro Valve, the K Pro Valve is one of the highest flow cylinder valves available today and is also a convertible valve. Whether you dive Yoke or DIN regulators this valve will work for both. Valve has easily removed 200 bar DIN insert to convert the valve for use with DIN regulators. Valve has a heavy duty deign with a smooth operating mechanism and multi-ported burst disc plug for added safety.

Aluminum cylinders unlike steel cylinders don't rust, they oxidize. The oxidization of aluminum forms a protective coat that hinders the continuation of corrosion making aluminum cylinders less likely to be condemned due to excessive corrosion. So if you want to shed the lead and use a more compact cylinder system then a standard aluminum 80 the Catalina Neutrally Buoyant Cylinder will fit the bill. When shipped the tanks valves will be removed and the tank will require re-inspection before being filled. All Catalina cylinders are nitrox Ready.

        I bought two of these and about to get another. I have also the so called norm AL80 but this tank beats any AL i have ever used. THey are negative and when you use it, compare it to norm AL, you will be surprised. The 3300 also makes it nice, just cant go wrong with these tanks.

        Questions about this item:

        Shopper  Why Did You Choose This?
        RICHARD G  Best price, best service, outstanding quality of product. There has never been a SLC failure of a Catalina tank.
        THOMAS W  What size "O" Ring ?
        Frank L  The outside oring on the pro valve is an R014. The one that comes with it is Urethane, but the standard buna orings will work as well.
        Glenn M  What is the Hydro date on this tank if I buy it? Glenn
        Frank L  They are all current hydro's from the manufacturer. Should be within the last year.
