I basically have 3 questions here today:
1 - The moisture disks are rated in relative humidity. What percentage is considered acceptable? I see that -50 dew point is specified some places for what scuba air is supposed to be, but I don't see how that translates to RH in the eyeball gizmo.
2 - When you put a new filter in the stack & the air gets dry again, does the moisture indicator change back to blue? or do you need to replace the disk?
3 - when the CO disk turns dark, will it clean up again when it sees clean air, or does it need to be replaced?
I'm trying to decide if I should buy one of those eyeball things, so I'd like to get an idea of how they can be properly used & relied upon.
Thanks
I have one inline... I never look at it and it doesn't really serve any purpose. Currently mine is an off white, slightly blue color. My tower stays under pressure all the time @ 2200psi+, my filter isn't old. It's just not as productive as I thought it would be. Maybe if I used my compressor more (which is maybe twice a month for 2-3 hrs?), idk... maybe it's something you should have, but you're hoping you never really have to use?
So to answer your questions
1.) I was told any humidity was unacceptable. If you've gotten to that point you've already used up your filter. Really shouldn't get to that point. If you do get a disk get the 10/20/30.
2.) I was told it should, but might take a while. Ideally, you don't want to wear a filter out like that. Better to be safe than sorry and change more often. I look at it like more of a check engine light than the service indicator @ x miles. If it's pink, something bad is going on. I wouldn't use it to know when to change filters.
Someone (
@rjack321 I think?) posted that you can use some heat (like hot air gun) and that works almost instantly to change them back. This works well for me. Absolutely no need to buy new. I think he said he's had his for over 10 years now? I had to do that when I 1st set mine up as the moisture in the air had turned mine pink.
3. I do not have a CO monitor disk... I was told it was pointless as when it does give you any indication that's already too much. Get a digital one like everyone else linked and analyze after.
With that said, I'm not an expert. My compressor is an oiless Rix, so I'm a little safer from hydrocarbons. Always learning, just passing on what I've been taught... good luck!
