N601RX Posted February 12, 2014 Author Report Posted February 12, 2014 Any filters on the outlet side? Most of the desiccant we use at work gives off a dust.
DonMuncy Posted February 12, 2014 Report Posted February 12, 2014 Must depend on the desiccant. Mine has no dust.
N601RX Posted February 13, 2014 Author Report Posted February 13, 2014 What kind are you using? Most of the commercial rechargeable media that we have used at work has dust warnings on it. The guys who handle it usually wear a mask. It's very fine, but you can see it when you open a new bag and pour it into the dryer. Most of the small desiccant bags that are used to ship sensitive equipment is made out of a special material to block the dust. Just check and make sure what you are using doesn't.
orionflt Posted February 13, 2014 Report Posted February 13, 2014 Haven't bought the desiccant yet, but may just have Don send me some of his extra. as for a filter, I do not currently have one installed but i do intend to put on on. I put in a check valve but ended up removing it because it caused too much of a restriction. I was thinking of using a piece of cheese cloth as a filter, I would just cut it to go over the top of the jar and hold it in place with the lid. Brian
N601RX Posted February 13, 2014 Author Report Posted February 13, 2014 Mine is activated alumina. I believe it may be possible to get a dust free version of the activated aluminum, but don't think all manufactures is dust free. Check their website or msds sheet. It's been a few years since I have been involved with using it but if I remember correctly some of the medical and clean room grades was dust free. We were using it to dry air that was being supplied to low friction air bearings. They have extremely tight tolerances and the dust would damage them. You should be able to get a sub micron filter with slip on hose connections from mcmaster relatively cheap. http://www.mcmaster.com/#compressed-air-filters/=qo3c6h
DonMuncy Posted February 13, 2014 Report Posted February 13, 2014 Thanks for the advice. I haven't seen any dust, but I could be mistaken.
pinerunner Posted February 18, 2014 Report Posted February 18, 2014 I'm going into a period of inactivity for a few months and I'm basicly going to "pickle" it using the special storage oil Aeroshell fluid 2F, drying sparkplug inserts, and low heat from my Reif preheaters (for that I'll use a variable transformer to step down to about 10-20%). I can see the idea of periodically running it but once all the oil has drained off the lifters, etc. I think it's better to minimize the number of restarts in that state. I put winter multigrade oil in it 2 months ago and haven't got the chance to fly since. But at that got the old oil out and a fresh charge in.
