Pressurized storage tank supplies water from reverse osmosis system when you want filtered water on demand or when the pressure from the system is too low.
Your RO system will fill the tank to capacity, and when you open your RO water dispenser the water is sent out to the RO faucet by the tank's pressurized air bladder. Unlike open air tanks which may allow pollutants in, a closed expansion tank such as the Amtrol keeps water sterile after purification. The tank uses stainless steel connections to avoid any leaching concerns, tested by independent third-party to meet NSF/ANSI Standard, and is CE approved under the PED (Pressure Equipment Directive).
Amtrol has made changes to their tank capacity. Please email us directly to check tank sizes in stock as they have eliminated some from production. If we don't have a specific Amtrol size in stock, we will recommend an equivalent replacement.
