Sentry I Open Air · Air Stripping
Air Stripping Package
Air-Stripping is commonly used to reduce hard-to-treat gases like radon and CO2, along with odor reduction from water. This package can be installed on either the G130 or G140.
Overview
The Sentry I Open-Air Air-Stripping Package
The G130 Series • Air-Stripping Package • 10 GPM • Open-Air
The Sentry I Open-Air Air-Stripping Package combines powerful aeration with chlorination to provide superior water quality. The Sentry I Open-Air Air-Stripping Package utilizes a ½ hp regenerative blower to best maximize the reduction of VOCs or Radon from your drinking water. The negative-pressure design — the EPA's suggested configuration — delivers the safest remediation of these contaminants.
Every Sentry I Open-Air System has three floats, one mechanical safety overflow, one electrical low-level shutdown, and one electrical water level maintaining float. While the unit fills, the chlorinator dispenses the exact amount of chlorine desired and the blower evacuates contaminants from the unit. The chlorine sanitizes the water and finishes the oxidation process getting rid of odors and killing bacteria.
The water flows into the bottom of the first chamber and then flows over into the second chamber where the submersible pump pressurizes the water to the home. The system is complete with the chlorinator, by-pass, bladder tank, pump, regenerative blower, and is pre-wired for an easy install.
"This system is often described as a personal municipality for the home — providing 24/7 protection."

Common applications
Where this system is commonly used
Problem gas
Radon
Air stripping is the effective approach for reducing radon from well water. (For methane, the Gas Reduction System is recommended instead.)
Odor
Sulfur odor
Helps address hydrogen-sulfide odor associated with well water.
Pretreatment
Ahead of filtration
Commonly installed as a pretreatment stage in a larger system.
System fit
How it fits into a treatment system
The Air-Stripping Package is typically positioned early in a treatment train, where venting problem gases such as radon and CO2 supports downstream equipment.
For applications that also require disinfection, dealers may pair air stripping with the Dry Pellet Chlorinator.
