Single-Blower Vacuum-Pressure Rail Unload System unloads powder, pellet and granular material from railcars at conveying rates up to 40,000 lbs/hr. One blower powers both sides of the system, minimizing cost, and is ideal for applications where the vacuum side of the system is a short distance. A PLC control panel provides manual start/stop operation, automatic shutdown on a high-level signal, and a selector switch for seven destinations. Premier Pneumatics, Inc. 606 N. Front St., P.O.
