Airsep question

searay495 said:
Hello all, revisiting the walker air sep topic, specifically the silencer/metal canister. I spoke to a rep at walker and he told me the canister portion of the set up was good for about 3000 hours. I explained to him how the silencer material in the end of the canister was deteriorating and he suggested just removing it. I took his advise and it's really nothing more than a heavy duty foam pad glued in to the canister. I was able to peel it out and sand papered away any remaining glue. If it's nothing more than a silencer pad, then other than "noise" how bad can it be. So two questions, has anyone else done the same, and can anyone explain to me how to read that little plunger valve with the red disk on the canister. What is its purpose? Thanks!

I removed the foam from 2 different boats with no problems. There might be a slight turbo whine but not enough to notice if you were not listening for it. Both sets needed painting anyway so they were prepped and re-painted at the time.
 
Just pulled my port airsep to do annual aftercooler maintenance. Foam is fully intact and not crumbly. 2200 hours on it.

One question. Walker says the separated gases are “reintroduced into the air intake”. Where exactly does that happen? Are there little holes somewhere for the gases to escape the coalescing filter compartment?

what is that little black push button thing on the upper right? I have that too but nothing in paper work about it.
Do these filters need to be oiled?
Is there a difinitive "Walker Air SEP Textbook"? These things seem to be way too complicated for air filters!

It’s basically a clogged filter indicator. If it goes red you are not pulling enough air through the filters.

Per Walker, filters should be cleaned and oiled every 250 hours up to three times. Then throw them out and buy new ones. They sell a cleaning and oiling kit.
 
I pulled mine off today not knowing if they are original, have ever been cleaned or what. They are not red in color, rather they're blackish after cleaning them. I cleaned them with k&n power kleen. Lots of red water came out, but they're still blackish, with some hints of red. Does that mean it's time to replace them? Engines had approximately 1,000 hours on them.

The red is the oil that you spray on after cleaning. The K&N kit should have the cleaner and oil. Mine looked like yours and I decided to replace them with new filters.
 
Ok, that makes sense now when I washed it a lot of red came out. Yes, the kit has both.
