Filters and Pressure Switch
- As mentioned before, This Tornado Kidde has an automatic moisture drain. When the compressor is turned off, an "oil safety" opens and allows the liquid in the moisture condenser to drain back out the way it went in. I'm hoping to be able to use this system so I took it apart for inspection.
- I found this inside had what looks like aquarium rocks about 2 inches deep and open air above that. I got the rocks out and cleaned it up with Dawn detergent. And, it looks clean and no corrosion on the inside. But the bottom elbow was partially clogged. I managed to unclog it but am wondering how likely it is to re-clog. The rocks are in there for condensation surface area I assume. I think this is usueable but I don't want to be taking it apart all the time to unclog that bottom elbow. I wonder how long they'd been running this thing with the clog?
- The filter is another story. The ends are held in by a steel ring in a groove.
I had to tap the top inward with a wood mallet in order to get at the steel ring. Once I got the top off, I found the tube nearly full of carbon but with about 1/3 of the bottom filled with moisture absorbent. I vacuumed out all of the filter media and found it completely corroded.
- So, the moisture condenser apparently didn't remove enough moisture. And the filter media didn't absorb enough moisture. OR, the previous users didn't bother to service this thing very often. Obviously, there are some very good reasons why they don't do things like this anymore. For now, I've decided I'll set this up to use the filter array from my RIX compressor.
- The next interesting thing is the pressure switch. Here's a photo:
