I have a Bauer K-15 w/auto drain that has started spewing water out of the exhaust filter whenever it shuts off. Drains are clear and running downhill. Collection tank is vented multiple times. I should add that the collection tank is still filling at what appears to be a normal rate. The exhaust filter is new. I would estimate that about a teaspoon of water explodes from the exhaust filter at compressor shutoff. I would appreciate any ideas anyone may have.

You need to increase the blowdown frequency. The drains use air as an actuator and the water in the air isn't being completely removed. I am a big fan of blowing down more often for shorter periods of time. I think if you give that a try, you won't have any more spewing out of the muffler.
Good luck!

OP
Can you give me an explanation of how to accomplish this? I assume it is the timing mechanism inside the wiring panel that has two knobs, ontime and offtime. The ontime knob has no scale around the knob and the offtime is set to 7.

You will need to post a picture of your timer mechanism for us to see what we are talking about.
Most have settings for when to turn on and another setting for how long to stay on. Run yours for a while and time it through at least two blow down cycles and see if that 7 corresponds to anything (like maybe 7 seconds blowing down). We can figure it out from there.

I would get this with my compressor. I made a little accumulator. It really didn't have to do with the time of the blow down but the force of the pressure blowing off. Coming out off the 1/2 hose was a lot of force with the air. The water would just spit hard into the filter. As I saw a lot of the new compressors they have an accumulator for the water and air to separate first.
See the picture of what I did. I used and made a PVC accumulator The blow off lines go into it first. I upgraded to ¾ pipe to the filter also. Since it started out ¾ then reduced to ½” line. Now the water and air hit the accumulator. The water goes gown and the air goes up. Since the diameter of the PVC pipe is bigger than the incoming lines the pressure is not as forceful. Also the blow off system is quiet now as you don’t hear the high pressure sound no more

aHeavyD,
Thanks for the picture. We built a similar accumulator and it helps considerably.

No problem. Glad that it helped. I've no problems since putting mine in.
Best part is I take my side cover off to check the oil and inspect the compressor every time before I start it and there is no mess in side. Before I had to wipe it down everytime as I like the compressor to be spotless.
