Moisture question

I wouldn't if it breaks open some how it will be all over inside just use dry air or nitrogen from a good known source

This is definitely a WAG having never tried it, but...

Thinking that the capacity for moisture absorption in those is very small, & not likely to help much.
Also not sure how well it would stick under high pressure, and would be concerned with it (or pieces of it) working their way into places you absolutely don't want.

Tried one of those desiccant packs in a blue Amazon cotton-filled metal in-line filter. Dessicant dissolved when wet, flowed to lower end of filter and re-hardened, completely blocking airflow. Blew out "O" ring in hand pump before finding problem. WM

Oh thought u ment a packet that might work I'm not sure

Personally, I wouldn't take the chance of a foreign object in MY air reservoir. That's just my $.02. Good luck.

Im talking about MicroPak stickers. It is a green, flat piece of tape. It has no pieces, no sillicon beads, no package…. Just green tape.

So just how much moisture can something that thin hold. Use your grain scale and weigh a length of clean new dry tape then let it sit somewhere with high humidity a day or so and then weigh it again. More tape will probably give more accuracy at that miniscule weight difference.
Let us know how often you need to check your bottle...

we all get old ya know lol ..

No.

Just make sure you are using clean dry air. Get a few drives on your pump or compressor and go that way.

You shouldn't add anything inside of an air reservoir. Dry air going in is the key.

puppadore,
would you need to crack into the air reservoir every time the tape gets saturated to maintain the degree of dryness that you want? If so it sounds like it might become a fulltime job

And prematurely wear out other seals by doing so.

Your better off controlling the air supply you use for filling ur guns.

These...

Absolutely stupid volume to have to fill each time, but, man it's good knowing the air in my gun is as good as it gets for a home setup.


(recommend just filling it with dessicant... The charcoal is for odor, and your gun doesn't care). (Unless you ever intend on potentially BREATHING the air (absolutely not recommending this, bad idea for a dozen reasons))

I would also recommend not only having a quality filter inline for your pcp airgun but one for your compressors air intake. A Very easy DIY filter for air intake can be made since in does not involve high pressures. I use to get moisture coming out of my bleed valve on my compressor when degassing the line but not anymore.

Why Not Pre Dry High Pressure Air When Filling Your PCP?

Most moisture-removal systems used with HPA compressors work on the compressed air side. An alternative is to pre dry High Pressure Air.

Honestly, the advantages of intake side drying are massive.

I keep thinking I should swap mine out and reduce the high pressure volume to speed up fill time

I thought the same thing but decided to play it safe do to the fact that heat and pressures build up within the compressor's air cylinder which may still cause moister even though the intake has a filter. After all your gun is as or more expensive then the compressor so that is my bigger concern.

But, I think filtering the air intake would also help extend the compressor's life span and put less strain on my inline filter so I don't need to change their elements as often (I still take a visual of their condition as usual) kind of a win win.

Good point. I can buy a LOT of compressors with the Edgun L2 alone...

I agree with the previous comments that putting any kind of moisture absorbing material inside your air tank, or the bottle / cylinder on the gun would not be a good idea. Just make sure that the air going in there is as dry as you can make it. Out of curiosity, I read the product info on the Micro-Pak stickers. They do not absorb moisture.
