The DuraFloTM 596 compressor is a two cylinder reciprocating compressor with a rated displacement of 27 cubic feet per minute at 1250 RPM. The compressor consists of a water cooled cylinder head and valve body assembly and an air cooled integral crankcase and cylinder block. The cylinder head is an aluminum casting which contains the required air and water ports as well as inlet check valves for each cylinder. [. . . ] An engine lubricated compressor must be connected to an oil supply line of at least 15 psi. pressure during the test and an oil return line must be installed to keep the crankcase drained.

Advanced Troubleshooting Guide for Air Brake Compressors * The guide consists of an introduction to air brake charging system components, a table showing recommended vehicle maintenance schedules, and a troubleshooting symptom and remedy section with tests to diagnose most charging system problems. INDEX Symptom Air Air brake charging system: Slow build (9. 0) . 26 Air dryer: Doesn't purge (14. 0) . 27 Compressor: Constantly cycles (15. 0) . 28 Reservoir: Safety valve releases air (13. 0) . 27 Page Number Symptom Coolant Compressor leaks coolant (17. 0) . 19 Oil is present: On the outside of the compressor (2. 0) . 20 At the air dryer purge/exhaust or surrounding area (3. 0) . 24 In the ping tank or compressor discharge aftercooler (8. 0) . [. . . ] Here are some Do's and Don'ts for prevention and thawing. Do maintain freeze prevention devices to prevent road calls. Don't let evaporators or injectors run out of methanol alcohol or protection will be degraded. Check the air dryer for proper operation and change the desiccant when needed. [. . . ]
