Air-Operated Double-Diaphragm Energy Savings
New Device Cuts Pump Air Use By Up to 50%

Proportion-Air's MizAir patent-protected electropneumatic smart device is designed to improve the energy efficiency of air-operated double-diaphragm (AODD) pumps by up to 50 percent. AODD pumps use large amounts of compressed air to operate, and the most effective way to make AODD pumps more energy efficient is to better manage the air they consume. The obstacle has always been that no two AODD pumps are the same, making it nearly impossible to design a product that consistently works. The MizAir uses fuzzy logic to analyze each stroke of the pump and "learns" the pump’s unique characteristics. The device then automatically makes internal adjustments to reduce the air consumption of the pump by as much as 50 percent, therefore reducing the energy required to run it by the same amount with little-to-no effect on pump throughput, fluid flow or flowrate. On approved pumps, no pump modification is necessary. The device is plumbed to the air input side of the pump and powered with 24-volt DC.
