Filter Magic® is a universal, simple, reliable and low-cost Filter Control System perfect for retrofit solutions or new construction. It was designed and patented to be a modular scalable dual Filter Control System instead of a traditional unique "integrated" system. High-performance instrumentation and Filter Magic® 2-wire K-Tork pneumatic vane actuators provide long-term maintenance-free and reliable control of the filters. The entire system includes a full three (3) year warranty. The system is completely scalable from a very small dual-filter water plant to a major facility with 40 or more filters.
