14.4.3 Oil in the adsorption dryer
The reason for high pressure drop may be the oil from compressor that saturated and
blocked the filters. If the oil comes in contact with adsorbent, it will destroy the the
adsorbent. If you see oil on the after-filter the adsorbent is destroyed, in which case the
adsorbent should be changed together with filter cartriges.
Check-up procedure:
1. Check pre-filter and after-filter for signs of oil and/or other contamination!
2. Change the filter catridges if needed!
3. If there is oil on the after-filter, change the adsorbent on both towers!
4. Service and/or improve pre-filtration!
Compressed air at the dryer inlet should be free of solid particles, oil particles and liquid
water. For more information on proper air preparation see the chapter
Installation Layout !
14.4.4 Dryer connected to the system in the opposite way
Although it may seem to be a unlikely or even impossible cause of high pressue drop, cases
like this do occur. Check the arrows on the top of the dryer that indicate the inlet and outlet
to make sure the adsorption dryer is connected to the system correctly.
14.4.5 Solenoid control valves malfunction
The cause of high pressure drop could be malfunctioning control valves. In this case the
pressure in the towers during adsorption phase will be much lower than the inlet pressure.
