Others Inline Filter upgrade for you handpumps!

[Danman]

Good day all, I have been wanting to stop moisture from getting into my PCPs (who wouldn't?!) and had been relying on my Hill MK5's included post dryer with desiccant beads and the color changing crystals. I was changing them about every 4/5 months but with the purchase of the Brk Ghost and its 480cc bottle, moisture has become a real issue. I would see water vapor at first from the bleeder after filling on the floor and then 2 weeks ago actual water droplets. I purchased an Air Venturi inline filter and realized the fittings were slightly different. I pulled the female fitting off the front and mounted it directly to the pump as they did work together at least. Now i can quick disconnect hose and filter from the pump and it stores easier, another bonus! Yes it takes a few pumps extra to pressurize the filter chamber as well but it's not to bad. I will never fill my guns up without it!

I would add that it's obviously not just a Hill pump issue, I see alot of pumps without a line filter. I do recommend the Air Venturi unit but be mindful that some messing around with fittings will be needed. Replacement filters are available and cheap but for my use it's mostly just to trap water. One other issue is the outlet female fitting is 1/8 BSP thread like everything else, but the male fitting is some other (pipe?) thread. I fully plan to pull the filter out periodically and dry them out to reuse or replace as required. And, Oh Snap! now it fits in my custom made bed drawer.... Has been stored on my wife's dresser since I got it

Hey @Andy65 I can not tell if that will work, I'd almost count on the fittings not working with whatever you have currently, worst case the threads are different too and nothing mainstream will fit so adapter fittings may be required.....the big question: Do they sell replacement filter elements?! I recommend the AV ones for that reason. I wouldn't be worried about the fact it's made in China, every inline filter I've researched is made there!

ok...if i drop out this idea..then what about replacing the dry pac material with a colour changing dessicant locally made and cheaper..will that work out?

That could work well, just gotta contain the beads so they don't go down the line. Something is better than nothing for a filter...cotton filter pads get wet, dissicant will saturate, keep it fresh or even pull it out and dry it and you'll be stopping a good percentage of moisture from ever getting into your pcps. Even grabbing some aquarium filter pad, stuffing it in there tightly would help. I recall a filter review video and the dude weighed the filter material before and after pumping up his gun. Kinda silly... if it had any noticeable moisture (weight) on the first fill that would be really bad, but I get what he was doing. After a few fills I will pull media out, let it dry out etc. Resist getting a huge one though or your hand pump will be hot just filling the line and filter up before filling gun.

in that case the first option could be better...ie that chinese filter...i mean it comes with reusable filters and the colour changing desiccant i have can also be inserted inside...but of course the pumping effort/efficiency has to be seen.my pump works fine but has to be rebuild after a few sessions because of moisture( i am presently using a microbore hose with it)..the dry pac also isnt quite cheap though i have suppliers locally who can provide me with similar micron size desiccant beads like what Hills at a much cheaper cost.

Danman, you really don't need to do all of this. What you absolutely must do is fill your gun with the fill line as close to verticle as you can get it, and bleed the line while it is still straight up. You should never pump for more than five minutes at a time so your bleed will get rid of the water, and after bleed, pump a few time with the bleeder open. The amount of air being pressurized with every pump is very small. The pressure itself builds the heat and condensation happens in the air but water is heavy and stays down, it does not shoot up the line like a squirt gun. Nor does enough water get generated in a five minute pump session to make it up the line. I have never had a drop of water in any of my pcp's doing this. I live in New England, not the desert South West, but Nomadic Pirate lived in Hawaii and he never got a drop in his airguns either. Remember to get a dead head and keep some pressure in your pump when you are done to keep the seals in place and the atmospere out, and you won't be working on your pump much, if at all. Mine is six years old I have never touched it, and it is a cheap $50 Amazon pump. Of course, what you're doing can't hurt and if it gives you piece of mind, press on.

Yes sir I 100% do everything you listed. Buuut the last strip down (I posted pics on all the moisture) it scared me so I got this. I consider it more of a 'gauge' as if/how much does actually get into the line. I can strip the pump and check moisture but I can't slit my hose and see inside that....with the filter now I just separate the body and check easily inside.

see this attached diagram..hills recommends adding the coloured dessicant on top of the dry pac..is this ok or should it be at the bottom?any advice

got this chinese filter recently...if i remove the dry pac attachment of my hills mk 3 pump and only use this in the pump microbore hose will that be ok?

I always put it at the top just like the instruction say. I’m going to go out on a limb and say that it’s easier to see when it turns green, indicating the maximum saturation of moisture.

What I don’t like about those is that you can’t see when it’s bad. Why do you not want to use the dry pac system? I live in Florida and it lasts three months of hard use.

I am currently running both the drypac and the inline filter. I saw too much moisture from the drypac standalone (changing twice a yr) to rely on it solely. Now I am certain 99.?% of moisture is not getting into my guns. The one @Andy65 is showing is similar to the AV one I have, crack the cap spin it off and inspect for moisture if curious. Beware though she'll take a bunch more pumps before it starts to fill the gun with this filter! I'd go for it myself. One BIIIIG problem with running just a drypac on intake side is it's always pulling moisture from the air even when not pumping, slowly saturating it while not in use. I actually spread the beads throughout the media and it gives a bit more of an accurate moisture "reading". The beads on the top will saturate and change color first...

Hi...how can i connect this black colour chinese filter with my hills pcp mk 3 pump hose...because the normal QCO2 quick connect as shown in item 3 in the photo doesnt slot inside the fill valve protruding from one end of this chinese stuff(the silver color one marked as 5)..even the quick connect on this chinese filter (marked as 4) is of a slightly different thread sizes though it does slot in my daystate huntsman classic pcp.i then tried using a chinese longer body quick connect which i have marked as 2 which slots quickly with the chinese filter however its leaking.can i use teflon on both ends of the 1/8 BSP to 1/8 BSP male adaptor (marked as 1) which ill have to connect with item 2 to achieve the desired connection while using my hills mk 3 pump(the 2nd phto shows the filler end of a microbore hose im using now to fill up my daystate which has in its end a normal QCO2 quick connect as seen)..pl advice

I experienced this as well, the quick Connects hook up but leaked, do not use together! What hose are you using... That is not a factory hill? Ideally try to get filter attached to hand pump and then run hose to your gun with correct fitting as in my photos. I got lucky with the AV filter I got. The FEMALE end I pulled off and hooked up to the pump. It clips into the male on the inlet of filter. Then you may have to go to a hydraulic/air industrial shop with your parts to hard mount filter to hose. I don't advise to use thread tape on the fitting with sealing washer. It may not be sealing bc bad gasket or wrong threads?

 

[Hateful McNasty]

Would a gravity type trap work

Then add your filters on the out side ?

im using a microbore hose....can you show me your arrangement using the AV filter

The first post on this thread I took some pictures of it. Ideal setup in my mind as this way the hose can be taken off and not left to flop around and wreck stuff (or get wrecked)! It stores much nicer this way as well.

Danman..see this photo of yours.i guess you have a quick connect installed in the pump(marked as 1 in red) and the hose line connects with that AV filter from the side marked as 2...is this correct?
