6.2 High Pressure drop
A high pressure drop will result in low pressure gauge readings or intermittent operation of the downstream equipment.
6.3 Downstream air supply interrupted
An interruption of the air supply downstream will result is a rapid loss of system pressure and failure of the downstream equipment.
Possible Cause
Action Required
Filtration has not been correctly maintained.
If the element and float drain have been installed longer than 12
months ensure that they are both changed.
Verify that the float drain is operating correctly.
The inlet parameters have changed.
If the inlet flow-rate has increased ensure that the filters and dryer
are re-sized accordingly.
If the inlet temperature has increased verify that the filters are within
specification. Ensure that the oil vapour removal filters and the dryer
are re-sized accordingly.
If the inlet pressure has changed ensure that the filters and dryer
are re-sized accordingly.
Contact Ingersoll Rand for details on particle counting and air
quality air measurement.
The compressor is not functioning correctly.
Check the documentation supplied by the compressor manufacturer
for troubleshooting guidance.
There is a pressure loss from the system.
Check for leaks in the piping and at connection points.
Ensure that all drain cocks and pressure relief valves are closed.
Check to see if the downstream flow-rate demand has increased.
The dryer is not powered up.
Verify that the dryers power indicator is illuminated. If the dryer is
not powered check the isolator and circuit breaker.
An isolation valve is closed or partially closed.
Check the position of all isolation valves.
