Inch Worm™ Technology

Our patented Inch Worm™ technology is an enhancement to all of the Evolve® series air-charged filtration products. This feature gently releases air, inch-by-inch, when the valve advances into backwash.

With traditional filtration units, this transition can cause noisy and frantic thrashing of the drain line. Much like releasing a balloon filled with air, where a large rush of air and water exits uncontrollably, sending the drain line flying if not properly secured. An Evolve® air-charged filter has advanced electronics to peacefully regulate the amount of air exiting the unit.

Filtration that uses a column of air is revolutionary in oxidizing sulfur, iron, and manganese to form precipitates (or solids) that can easily be filtered and removed, all in a chemical-free solution. They are some of the most effective point-of-entry filters on the market.

A filter capable of utilizing Inch Worm™ technology is the perfect solution to effectively reduce sulfur, iron, or manganese, with worry-free regenerations.

How it works

The first cycle that an air-charged filter enters when regenerating is called the “Backwash Air Position.” In this position, the electronics control the valve as it goes through a series of very small movements, “inching along."

As the water level creeps to the top of the tank, air is released slowly and, more importantly, harmlessly down the drain. This Inch Worm™ allows for the filter to expel the pressurized excess air without the violence associated with other air systems.
