de-hum system
Frank, will you share your single pass dehum system? It sounds interesting and smart.
Really simple, most of the benefit I'm sure is to get the hot sweaty air out of the crankase before it cools and condenses. but this is cheap and foolproof so why not?
Take a 10ft length of 1.5" ABS pipe (Home depot) and 4 caps. Cut the 10ft length in half and glue a cap on each pipe. The top caps just get pushed on.
Take 4 1/4" brass hose barbed fittings with 1/8th pipe theads on the other end.
Drill holes in the plastic caps mentioned above and self tap a fitting into each cap.
Fill tubes with desicant from harbor freight...buy two 5lb bags ($5 each) and fill ABS pipe and replace caps..You now have two columns.
Buy a PETCO own brand aquarium pump ($15) ..they are blue/grey and pretty large..
Connect output of pump to the bottom of first colum..out of the top and into bottom of second column..out of top and into the breather hose on your engine. All this with flex PVC tube.
turn on pump and very dry air will ventilate through crankcase.
After 6 weeks or so (western oregon) the blue desicant will turn pink, so I take it home (I have a little spare I put in the columns which is good for a week) and bake in the oven at 300F for 5 to 6 hours to trun it blue again.
Thats baically it..I have a little clear tube on the discharge of the second column with an ounce of dessicant so i can see when its time to recharge..I.e when that tuns pink..all of it is pink.
