ABCwaters 3.2 Gallon Pressurized Storage Tank for Reverse Osmosis (RO) Systems

The reverse osmosis process is on the slower side, so a pressurized storage tank is typically required to supply water from the system on demand. Your RO system will fill the T32M tank to capacity, and when you open your RO water dispenser the water is sent out by the tank's pressurized air bladder. The concern that pollutants may be allowed in when using an open-air tank favors the use of a closed expansion tank such as the T32M. The tank uses stainless steel connections to avoid any leaching concerns, is NSF approved under standard 58 and is CE approved under the PED (Pressure Equipment Directive). 


- Stainless steel 1/4" NPT valve thread connection to connect to RO systems and other water producing applications.
- Smooth internal air vent cap prevents diaphragm damages. 
- High-grade butyl diaphragm and post-cure procedures ensure a safe, tasteless and odorless water chamber.
- Discharges effectively in a vertical or horizontal position. 
- NSF 61 and 58 listed. 
- IAMPO approved. 
- CE Mark approved
