Problem Possible Cause Repair Comments
Water in system
Inlet and outlet
connections are
reversed.
(compressed air)
Check inlet and outlet
connections.
This dryer is designed for air
flow in one direction only.
Inlet and outlet directions are
identified on the dryer.
Drain system is
clogged or
inoperative.
Free drain of obstructions,
or repair drain, and make
sure condensate water
drains properly.
Drain system may be a timed
solenoid valve, pneumatically
assisted or zero loss
condensate (float) drain.
Adjust solenoid in accordance
with operating conditions of
your compressed air system.
Check & clean the solenoid
valve strainer periodically.
Bypass system is open Check the valves
Important: Install bypass
piping around the dryer so the
dryer can be isolated for
service without shutting down
the air supply. During dryer
operation, valves must be set
so all air goes into the system.
Excessive air flow
Check actual flow through
the dryer.
The dryer allows for maximum
air flow. If too much air is
pumped into the dryer, water
removal capacity may not be
sufficient, resulting in water
carry-over downstream in the
compressed air system. Check
the rated flow of the air
compressor.
