Wabtec Air Dryer Units for Transit Cars

The E-1A and E-1A HP Twin-Tower Air Dryer Units used in Wabtec compressors are engineered for high-duty-cycle operation.  These units provide consistently dry air with minimum post-compression air consumption.  Featuring continuous output, this dryer purges one desiccant tower, while the other tower performs the drying cycle.  Components include a spin-off, bead-type desiccant with built in prefilter, a mechanical liquid separator, an R-1 drain valve, a coalescing filter, a main reservoir check valve, an integral thermostat and heater and a control timer.
