Mount your setup vertically and have your tank upright. Meaning make it harder for the water to get up into the tank inlet. Then after charging and air has been released, open your 3 different filter stages and drain/air out. Thanks for the video

Great video! Using a Yong Heng compressor and an 88 cubic foot scba tank, I was able to fill from zero to just over 4,500psi in just over 80 minutes. I ran the compressor for 15 minutes at a time, and took cool down breaks between 15 min and 30 min depending on temperatures. As far as filtration, I only used the OEM moisture/oil separator that came in-lined with the compressor. I did get moisture, but, not too bad. Later this week, I'll be working on a bigger / hybrid filtration unit, so in the end, there will be a small and large filter using both cotton and Molecular Sieve. I think that'll be the best bet to limit any sort of contaminants [moisture / oil] Sam -

Your 3rd stage filter ( the brass one) should be in a vertical position while charging the tank not laying down so that any water and oil will stay in the bottom of the colum.

I limit the time for my compressor to run, allowing for a certain amount of "cool down"...it takes a bit longer but i have a little bit more peace of mind(even if its just a placebo)

I like your videos, very well done. 300 bar means 300 x 14.7 (atmospheric pressure) so 300 x 14.7 is really 4400 psi.

👍 Getting out of powder to air. I have tech Experience. I researched all I can research. Clean air is good air! I have seen equipment failure at 200 psi and hydraulics up to 1500 psi, don’t want to see the upper pressures of PCP!

I like your video and would like to see your follow up video. I have a Omega Supercharger and also have a Air Venturi Nomad2. I also have the large Omega Cartridge Filter that has a non-fiber cartridge filter that has four different stages of materials to the cartridge. I have yet to utilize my equipment. I'm wondering with all these filer devices you have hooked up how much time and running of the compressor occurs. It seems to me that your setups would indeed require a lot of compressor running. When you go to purge the lines it would it not you be a enormous amount of air lost ion doing so. I have a lot of money tied up in fiver top quality PCP rifles let alone the high cost of my compressors. I finally will have the time to work with my Rifles but I for one are concerned as to safely and properly utilizing such High Pressure rifles and devices. Your reply would be appreciated and have you completed your follow up video?

what size female foster fitting would the separator need to fit my Benjamin Marauder?

The input is the male foster unless you reversed them. Let us know how it does. Thanks for the vid.

I'm researching to see if i can use that tuxing 'gold' colored filter you have in this video to connect up to my g7s air venturi hand pump output & use it to air up my diana storm rider2. does it use the same quick-connect foster fittings and are the threads 1/8" bspp?

Air from these small compressors contains water, oil, smoke from burned oil (most oils burn spontaneously in high pressure air), and 100% humidity (water vapor). The filters being used here will gather liquids and some of the smoke particles but not the water vapor. The last filter should be one that grabs water vapor such as a molecular sieve. Using high pressure compressor type oil will eliminate the smoke and burned oil. Happy Shooting!

Yikes, that's a ton of oil in those filters which seems like they should be changed before they become entirely saturated (at which time the oil is headed downstream). Hopefully the oil reservoir isn't overfull or the piston rings aren't working properly, etc. Hope your third stage does the trick :)

Dear Re loader love your videos. One question. I got The Tuxing Oil water saparator filter. (Same as yours) Doesn't pass air ,does it have to build pressure . To pass to the other side? My was at 2000 psi and no air to the side of the hose (where it connect to my pcp air tank.) Thank you. Great informative videos.👍

Make sure u have the filter standing up alex

Where did you get those brackets that your tank in the background is sitting on?

Ordered mine right now. Bought another one last week from a different company and the damn thing was rusted inside and had no filters!

Does anyone have the small Tuxing compressor that is air cooled...also 4500 psi. Was wondering if it would push air through that size filter! It does fine topping off pcp's to 3000 psi and only takes about 3 minutes. Around 5 minutes if its empty!

Hi! How is the tuxing filter doing? I notice the threaded portion is too shallow.

300 BAR is about 4,350. Even though it's advertised as being 4,500... that compressor won't last as long pushing it to that pressure. Regardless of how cool it runs, I wouldn't run it for more than 15 min, max at a time.

Do you have a link to where that filter can be had for that price? I can’t find them anywhere less than $125. Thanks Excellent video!!

How long do a set of Tampons last in the filter? Setting mine up right now. Good video..

After just recently getting my compressor and finding out the stock filter does next to nothing as far as separating water, I have 2 more smaller filters on order, they’re like the stock one. My plan is to use cotton/molecular sieve/desiccant beads in each. Decreasing the amount of cotton up through the filters and increasing the amount of molecular sieve. It was a cheaper route than getting the long, gold one similar to yours but with the enclosed sieve inside. Hope it works just as well. Hope you’re getting good results with yours. If you want to follow along with my project, I’m at “Cheap Airgunner “ on KZfaq.

Put small filters first. Easier to check those filters first.

I really can't understand why peoe are wasting time on those white moisture filters when what is actualy required is an empty space and a tap at the bottom of the water separator with dessicant or molecular sieve medium at the mid to top end. And whilst I'm pionting that out those separators will also work more effectively if stood verticaly with inlet at the base and outlet uppermost. It really straightforward logic that as the pressure rises the water will condense out of the air and go to the lowest piont where it can be drained off manually whilst pumping is in progress.also like I pionted out water will be passing almost unhindered through the entire system untill it reaches such a pressure that it is forced out from between the molecules of air. So technically the ideal situation would be to have a regulator between the water separator output and the tank that you are filling so that the water is aways being wrung out of the air before your tank even begins accepting a gradual fill. But it does require for the compressor to constantly be running at the pressure that you intend on filling your tank to or greater and the regulator will gradualy open as the two sides of the system gradualy equalize.

I thought 300 bar was around 4300psi? Many spoken errors in your video
