RO pressure tanks, also known as bladder tanks, hydro-pneumatic bladder tanks, or captive air tanks, are essential components of RO water systems. These tanks operate by filling a food-safe bladder with water, which is surrounded by an air cushion, allowing the tank to dispense water effectively.
Not all bladder tanks are built the same. Tanks designed specifically for reverse osmosis water storage feature stainless steel connection points, which are resistant to corrosion, unlike common steel used in regular water storage tanks. Our RO tanks can be used either horizontally or vertically without affecting performance.
If your RO water tank’s performance is declining, try re-pressurizing it before considering a replacement. You’ll need a pressure gauge and a bike tire pump.
*Note: We offer a comprehensive warranty on our tanks: a full replacement in the first year, 50% off in the second, and 33% off in the third.
At Air, Water & Ice, we offer a variety of RO pressure tanks suitable for drinking water kit and saltwater aquarium systems. Explore our available sizes and accessories:
This is currently our lowest-capacity RO pressure tank. The 2.2 gallon NSF certified RO pressure tank, hydro-pneumatic bladder, and captive air tank are all commonly used names for this water storage tank.
It works when water fills a food safe bladder which is then surrounded by a cushion of air, earning it the name of “bladder tank.” Dimensions for this size tank are 14” x 9”, weight 7 pounds, and a rating of up to 75 psi.
A step up is the 3.2 gallon storage RO tank. The dimensions of this higher capacity tank are 11” x 15”, with a weight of 8.08 pounds. If you need a bit larger of a drinking water solution, this tank is a better fit for you.
Note: The ¼” quick connect tank ball valve is not included in the purchase of the 3.2 gallon RO pressure tank.
This larger-sized RO tank is rated for up to 100 psi. Dimensions for this tank are 12” x 18”, and its overall weight is 10.24 pounds. Please note that you can add the ¼” and 3/8” tank ball valve but the valves are not included with the base RO tank.
The 5.2 gallon storage tank has an Air, Water, & Ice warranty that includes a one-year full replacement, second year get 50%, and third year get a 33% discount.
Double the size of the 5.2 gallon RO tank, this is a much larger product for accommodating larger RO systems. This NSF-certified RO pressure tank comes equipped with a 1” female NPT opening. The dimensions of this tank are 26” x 16”, with a weight overall of 24 pounds.
The rating for the 10.7 gallon RO pressure tank is 90 psi. Please see our reviews which demonstrate the quality of this RO pressure tank!
Lastly is our 20 gallon storage tank. Its size accommodates both home RO water systems as well as well as pump water storage tanks.
A stand is included with the purchase of this tank, and it also comes equipped with a 1” female NPT opening. Dimensions for this large tank are 16” x 32”, and it weighs a total of 37 pounds.
In addition to your purchase of RO pressure tanks, you may likely need the tank ball valve elbow part (available in either the 1/4” or 3/8” size). We also have the stainless steel 150 PSI gauge available to add to your RO or RODI unit.
In this category, we’re also selling the Pentair structural tank, accumulator tank, and saltwater aquarium anti TDS storage tank. More information about those products on their individual product pages.
