AMI Water Storage Tank for Home RO System


AMI RO water storage tank is used in home reverse osmosis systems, including AMI AAA and AAA-RO Series Home RO Systems to store reverse osmosis water. This tank may be used as a replacement or to upgrade the reserved water volume in most home RO systems. AMI pre-pressurized storage tank has an approximate storage capacity of 3 gallons with a 1/4" MPT connection, and is equipped with a schrader valve for checking air pressure. NSF tested and certified against ANSI/ NSF Standard 58 for material and structural integrity requirements.

The bladder tank is used to store the RO product water and dispense the water to the faucet using air pressure within the tank. When the tank bladder is full, the pressure is sensed by the system's shut-off valve (sold separately) to shut off the RO system by closing the feed line. Water will remain in the bladder until the faucet is opened, the air pressure surrounding the bladder will force the water out of the storage tank and to the faucet. As water is used, the pressure will drop until the shut-off valve disengages, allowing feed water to the RO system to resume until the tank is refilled.

Tank valve and auto shut-off valves are sold separately.

Good fit, good value
Style: CF12436 Classic, Style: CF12436 Classic
Purchased this filter for my 2023 Outback. First off changing the cabin filter on this model Subaru is amazingly easy and can be done with no tools and no more then 5 minutes. Pictures posted show packaging, the paper "Blue" filter side, the "Black" charcoal side and the foam outer edge. The filter is well made and is very sturdy as the outer shell is plastic vs. other paper filters that are more flexible. Holding the filter in your hand and giving it a slite shake you can hear the activated charcoal within it. After installing the filter I had a few trips in the car, did I notice any difference in the air quality coming into the cabin....... no. But does this mean its not working? also no. What I can say is the filter fit snug and left no gaps, and with the plastic surroundings and foam in sure the filter will not be letting anything get by as it passes through the system. All and all this filter is well made and sturdy, and seems to be a good value with other paper only filters being about the same price.
