Air Dryer
Air Dryer part number and/or vendor: ____________________________
Maximum allowable temperature to the dryer: 160
0
F
(Bendix Air Dryers Requirement)
Minimum allowable temperature to the dryer: 45
0
F above lowest ambient
(Bendix Air Dryer Requirement)
Recommended Test Procedure:
Install a temperature probe at the air dryer inlet fitting. Operate the vehicle such
that the engine is at operating temperature. Drain an air tank such that the
compressor runs continuously, but the pressure remains about 10 psi below the
governor cut-out pressure. Note the dryer air inlet temperature after the
compressor has run for 90 seconds with the engine running at rated speed. Also
note the ambient temperature. To obtain the maximum air inlet temperature, add
the difference between the recorded inlet temperature and the noted ambient
temperature to the maximum expected ambient temperature. Likewise, add the
temperature difference to the minimum expected ambient temperature.
