Question on air filters

As a newbie, I am often reading how moisture is a mortal enemy of the PCP. Would using a filter between an large CF air tank and the PCP tanks I look to fill up help in that regard? If so, what would be recommended that I use to filter the air from the CF fill tank to the PCP bottle? Also, as the PCP tank heats up, doesn't that generate some moisture as it cools down? When I do a fill, I do it very slow and stop adding air to the PCP tank once I feel a slight amount of warmth and never let the tank get hot, by waiting a good 15 to 20 minutes before adding more air. Until I learn otherwise, I will continue this method and hope that I learn this is completely unnecessary.

Gosh I am really starting to hate this stupid 2 minute rule thing. I sure hope it isn't something that will continue once I reach 10 posts. Speaking of post's, how in the world will I know if I have accumulated 10 posts or not?

Welcome to the Nation. I see this thread was started twice and Brent's answer on the other sounds right. Almost everyone will make an effort to keep moisture out of the air going into a tank, so no additional effort is required to further dry air going into gun. There is an active thread about whether desiccants (drying agents) are always needed in HPA. You might find that thread enlightening.

I regret if you took offense to a slow response to your posts. Please understand we welcome many with open arms, almost daily, on this site, and are glad to do so. I've only been in the Nation less than half a year and even I'm tired of guys looking to post 10 times to be able to use Member Classifieds. I'm not saying, at all, that is what you're doing, just when you mentioned how to know when 10 posts are reached, sounded familiar. This forum is filled with some of the kindest, most knowledgeable band of brothers (and sisters) I've ever had the pleasure of knowing, and you are more than welcome to be a part, I hope you take advantage of this opportunity. Best Regards,

WM

Temperature change in a closed system cannot generate moisture, so a slow fill will make no difference to the amount of moisture, but always a good idea to fill slowly, this will protect the o-ring in the inlet valve from heating up and make it last longer, but no need to over do it

Thanks WM for your reply and please note I really wasn't offended by any slow responses. It was just me being impatient with the whole new experience on this board, with seemingly new rules popping up each time I attempted to post something toward becoming a defacto AGN member with privilege's. It is partly true I wanted to get in my 10 post to use the classifieds as I seek to expand my "airsenal". However, I have a even larger want to learn as much as I can about all aspects of air related platforms and accompanied accoutrements and will indeed to picking the brains of as many of the 600k+ members I can. What a great resource pool to garner more experienced and expert opinions and knowledge from and can't wait to start bombarding forum members with all my many questions!

Hej Mr. Towle! I greatly appreciate your sharing your knowledge about moisture when filling bottles. Now that I look back on my question or comment, it sure shows the elementary level I am at on understanding air systems and pneumatic physics. I really had no idea that moisture would not form in a closed system. That is great to know and now I can remove one more of my host of air fill concerns, thanks to you! I do use a microbore hose to facilitate a slow fill, yet still amazed at how hot the bottle gets when doing a full uninterrupted fill. Which I never did after my first solo fill as a result of the bottle getting pretty hot. I was really worried that this thing might explode. Of course namely due to my not having a whole lot of experience, and confidence in using HPA at these extreme pressures. I'm still very cautious and more accurately, hyper vigilant in protecting myself from a self perceived incident in using HPA systems and the more I begin to understand about the physics / dynamics of HPA, I am sure my unsureness in time will diminish; I hope.

Thanks Hynzie for letting me know where to check this. I'm almost overwhelmed at all the nuances of AGN's communications platform and still learning how to navigate myself around, lol. On another note, sorry to opine, but I really don't like this 2 minute rule post thing. Especially when I have more than one replies to catch up on. I like to quickly key up my reply and move on to the next topic or search experience, lol. 

I do wonder if you compose a post and something happens when you click "submit" and it doesn't post for whatever reason. Do you loose everything you just typed up or is it cached or saved somehow?
