Also, verify that the working pressure is adequate by checking the outlet pressure of the compressor and the pressure drop over the dryer and filters. Poor regeneration could also be the cause. In this case, check if a purge nozzle appropriate for higher working pressure installed, regeneration silencers clogged (the regeneration pressure should be less than 300 mBar) or if other described symptoms are applicable.
