wabtec westinghouse air brake Air Dryers - 975 Series Twin Tower Air Dryer System

975 Series Twin Tower Air Dryer System

The 975 Series Twin Tower Air Dryer System is designed to deliver Dry, Oil Free and Clean air to the entire locomotive and train compressed air system. With almost three decades of service the 975 model has earned its reputation as the most widely used and dependable regenerative pressure swing dryer system in the North American railroad industry. The system is engineered as both a filtration and continuous drying package in one. A high ef ficiency coalescing filter removes liquids, sub-micron aerosols and solid contaminants. Simultaneously, two towers filled with a highly adsorbent desiccant reduce the relative humidity of the compressed air. With dry compressed air, the problems of corrosion and freezing of pneumatic components are eliminated. Removing compressor oil, that has become varnished due to the heat of compression and the shearing action of the compressor , keeps orifices from clogging, valves from sticking and metal surfaces from pitting. Solids like rust, scale, dirt and particles from compressor wear are also removed. When left unchecked, and placed in a high-speed air stream, these solids act like a sand blaster and erode components. The benefits of Dry, Oil Free and Clean compressed air are reduced locomotive and car down time with substantial cost savings.

wabtec westinghouse air brake Digital Air Gauges

Digital Air Gauges

The 737/758 digital pressure gauges and 747/768 digital AFM’s are the latest innovation in cab air gauge technology. As with the analogue pressure gauges, the digital pressure gauges come with dual displays. This dual function does the work of two single gauges, requires half the panel space, and costs less. The auto-dimming feature provides optimum viewing of the digital display under any ambient light condition. All digital gauges will interface with the standard gauge base which makes them to be interchangeable with current Wabtec analogue gauges. The standard gauge base also allows the gauges to be removed without disrupting the pipe connections. All digital gauges are able to be calibrated in the field and the digital design allows for longer intervals between calibration. The 758 digital pressure gauge and 768 digital AFM come with AAR compliant, 8-pole, A-coded, female M12 Ethernet connector. Digital gauges and AFM’s are available with either green or black faceplates.
