Back to Reverse Osmosis Di Units

All Pinnacle RO units use the highest quality components available and feature modular design to ensure easy accessory add-ons.
All Pinnacle Units utilize John Guest© high impact poly quickfit fittings. Across a host of applications, John Guest fittings require no special tools. Simply cut the tube square and insert it into the fitting to effect a secure and reliable connection.
With Pinnacle RO units, you can always check the pressure of water moving through the membrane because, pressure gauges are standard on all Pinnacle+ units.
Also standard on Pinnacle RO units is an automatic shut-off valve for easy addition of top off or drinking water systems.
External flow restrictors for easy accessory add-ons come with select units and will soon be standard on all of the units.
High Performance Filters. Each unit contains one carbon pre-filter to ensure long membrane life and one 1 micron sediment filter.
Reverse osmosis, also known as hyper-filtration, is the finest filtration known. This process will allow the removal of particles as small as ions from a solution. Reverse osmosis is used to purify water and remove salts and other impurities in order to improve the color, taste or properties of the fluid. It can be used to purify fluids such as ethanol and glycol, which will pass through the reverse osmosis membrane, while rejecting other ions and contaminants from passing. Reverse osmosis uses a membrane that is semi-permeable, allowing the fluid that is being purified to pass through it, while rejecting the contaminants that remain. Reverse osmosis is capable of rejecting bacteria, salts, sugars, proteins, particles, dyes, and other constituents that have a molecular weight of greater than 150-250 daltons. The separation of ions with reverse osmosis is aided by charged particles. This means that dissolved ions that carry a charge, such as salts, are more likely to be rejected by the membrane than those that are not charged, such as organics. The larger the charge and the larger the particle, the more likely it will be rejected.
Rejection is the term used to describe what a reverse osmosis filter removes from the source water. Pinnacle+™ reverse osmosis filters allow for an overall rejection of 99% of all impurities of source water.
