This is for a pressurized oxidation system for a shallow well…we did not install all of this equipment originally, but rather modified it with our custom booster system which supercharges a standard water conditioner…the original installation utilized an electric air compressor that ran with the pump, but did not enhance the pressure. The max pressure prior to our modification was 45 psi after the conditioner, and even less on the third story. Our custom modification not only injects more filtered air, but boosts the overall pressure, past the conditioner, to 70 psi. This customer lived with poor pressure for over 10 years, and now is very happy.
