FUNCTIONAL DESCRIPTION The Proportion-Air, Inc. MizAir is a revolutionary new device that is specifically designed to reduce air consumption of Air Operated Double Diaphragm Pumps (AODD). It’s patented control effect allows for the reduction of air consumption of up to 50% with minimal loss of fluid flow. The only requirements from the user of the MizAir is a 24VDC power source and to insure the MizAir is close coupled to the pump. The MizAir utilizes a microcontroller controlled air dispensing system. The MizAir consists of a high-flow normally-open two-way valve and an electronic control unit. The high-flow normally open valve delivers precisely timed pulses of air to the pump at the beginning of each pump stroke. The MizAir valve then closes. The air that has already entered the pump and has started the pump stroke is left to continue expanding and finish the stroke. This results in the pump ending it’s stroke with less air entering the pump for a given amount of fluid being pumped. Since less air enters, there is less air to exhaust as well. This helps the pump start it’s next cycle because there is less resistance to the return stroke. Less air to exhaust also produces lower exhaust noise levels.

The MizAir utilizes an internal pressure sensor to monitor the air being supplied to the pump. The characteristics of this signal allow the MizAir’s microcontroller to determine when the pump reaches the end of stroke. This information is used to time the pulses of air entering the pump. The MizAir is an intelligent device and is able to continuously monitor the speed and other operating parameters of the pump and make adjustments to the valve timing as needed The MizAir is designed and built by Proportion-Air, Inc. to meet the demanding requirements of diaphragm pump control. The MizAir has a fast response time (<30ms), low power consumption (<275mA @ 24Vdc) and high cycle life (more than 25 million cycles). The result is a lightweight compact anodized aluminum two-way valve which is mounted directly to our control circuit in a NEMA4/IP65 rated assembly which is ideally suited to the kinds of environments in which diaphragm pumps are often installed. |
