The Wilden? Pro-Flo? SHIFT (PS) is the industry's premier air distribution system (ADS) and your ideal solution to increase productivity, lower energy consumption, reduce air consumption and simplify maintenance. With design benefits unmatched by any other ADS on the market, the innovative, yet simple PS features an air control spool that automatically optimizes air consumption and eliminates overfilling of the air chamber with no reduction in flow rate. This design conserves energy while maximizing mean time between repair (MTBR) for your air-operated double-diaphragm (AODD) pump. Ideally suited for a wide variety of industrial applications, the PS is your go-to solution to maximize productivity and lower costs.
