Pressurized RO Storage Tanks

Flexwave Composite RO Pressurized Diaphragm Storage Tanks
Flexwave FWRO Composite Pressurized RO Storage Tanks

Flexwave RO Water Storage Tanks use a butyl rubber diaphragm to store and deliver reverse osmosis water using air pressure within the tank.  AMI stocks Flexwave tanks in up to 80 gallon (302 liter) volume.    Flexwave composite tanks flaunt a seamless polypropylene liner that eliminates top and bottom leak issues, as well as stainless steel reinforcing rings that back up all threaded openings. Injection molded domes increase shape consistency and strength while wetted surfaces made of high quality polypropylene add zero taste or odor.
