For sale is a Speedaire (Built by Dayton) 5Z656E Refrigerated Air Dryer. 1/4 HP AC Compressor motor. Operates on 1/60/115V Single phase AC. 21.9 SCFM Throughput capacity. R.L.A: 5.3. L.R.A.: 29.0. Uses 20 ounces of R134A refrigerant. NOTE: I have performed a basic "power on" test of this air dryer; it fires-up and sounds very good. I cannot test for air drying capacity, but there appear to be no issues with this unit.
