So, how many of you guys have topped off a SCUBA tank from 2000 to 3000 psi? I'm just curious if it's going to be worth it to try one of the less expensive/smaller compressors to top off my tank or if I should try to keep using the local fire department to fill the tank.

+1

Or even 2700 to 3000 psi (a good afternoon is about 300 psi for me).

  Would you post some pics of how you loaded the Xin Yong filter.  just ordered the extra filter and beads .
   Thanks Pete

I did not think to take any pics of the liner with the guts in it. Its not very scientific other than the research on the best molecular sieve medium to use. When you get your filter it will have two paper filters that run the full length of the unthreaded portion of the tube. They have no liner included so that's where I decided on the thin vinyl type of cutting board. Just cut the vinyl the same length as the inside the body of the tube minus the threads. Then roll it up to form a tube and size it so when its rolled up the correct size to be a snug sliding fit and there is about 1 1/2 to 2 inches overlap on the liner. I rolled it up outside the tube to get close for the first cut and then installed the cut piece in the tube and mark each end where I wanted the final overlap to be. Cut and use the clear packing type of tape or similar tape to tape the outside of the liner in that size tube and tape the full outside length along the seam of the tube.

Then cut the paper filter that's included into 2 two inch lengths to pack at each end to hold the sieve medium. I placed one cut paper filter piece in one end of the vinyl tube till its flush with the end of liner. Stand the liner up vertical and slowly pour the medium in the liner until there is about 2 inches of the liner left unfilled. Then holding upright still tamp the end of the liner on the table with your hand around and even with the end liner so your hand cushions the hammer effect. You are trying to compress the medium so its packed tight as possible with out crushing or compressing the beads of the medium. When you are satisfied that you have it filled so you are happy with the height of the filter and medium in the liner.  Screw both caps on and judge if its a snug fit. Then remove liner and one filter from one end and pour the beads out into a container to reinstall in a bit but leave the previously installed paper filter portion in place in the bottom of the liner. The idea is to make the stack of paper and medium in the liner so that with both caps screwed all the way on and tight is that the liner and mediums are held snuggly in the sieve tube.

Now with both caps off the sieve tube slide the liner into the sieves tube until the end with the paper still in it is even with the start of the threads in that end and screw that cap on tight . Then refill with sieve medium and tamp it down lightly. Then install the other paper filter in the end and screw the cap on tight and install fill fittings.

Empty scuba tank took me over an hour with this compressor but I do not recommend it. Topping off a scuba tank took me from 4500 down to 4000 15 minutes to top off at 4500. 2000 to 3000 would not take a lot to top off. I just would not do a empty scuba tank from empty. Now it can be done as I demonstrated in my you tube video in steps. This compressor is not designed to fill an empty scuba tank. Topping off one I personally would do or small guppy tank or airgun itself👍🏾

Thanks guys.

This is one that I was looking at to consider. I just haven't read enough about the compressors in general to know what I might be getting myself into.

The compressor in your link looks a lot like the air Venturi blue one but in red😳 Hmmm

[Rich_B]

Nah, they don't do that kind of stuff over there.

Think that one should work for a tank top off ok?

Yes, that compressor will fill a scuba tank no problem

Well you should go to TAG and read the review on the nimrodair compressor that guykuo posted. Just to know what you might get.

Mine is holding up just fine. Glad I bought it👍🏾

To help the cooling, this product may work great.  I have been using it for years in my dirt bikes when I run just water in the radiators.  It does drop the temps better than just plain water.  It is also totally safe on metals.

Pretty much the same stuff I'm running in my bucket. I can't tell a difference but then again i never ran it without the stuff in the water. I figured it couldn't hurt anyways.

So the water wetter did not bring down the temperature in the bucket?

I don't know because I never ran just straight water. The stuff worked great in my car when I used it though! I haven't been able to shoot much due to wind and lack or squirrels but when I need to top off my guppy I'll post what max temp gets to.

As far as trying to keep the air as dry as possible, what do ya'll think about putting a desiccant filter on the input of the compressor? It's done on one brand of a hand pump. I have two of the Harbor Freight ones I bought some time back and am thinking about taking the little filter off they put on and putting the HB one on after the one that came on it. Just worried it might cause it to run harder trying to not so good air in.
And I also found a larger filter for the output side like was posted earlier here, more $$$ too, but is a little larger.

I am using the stock output air filter on the output side and on the same line using the diabolo air dryer system same as the one from AliExpress but red in color as double protection with no problems thus far

Just a side note on the water wetter, it should make the water in the bucket hotter because you are drawing more heat away from the cylinders. It reduces the surface tension of water so it can draw heat from metal better without boiling and creating steam pockets which do nothing to help cooling. I've noticed the effect when running it in my bikes, the coolant warms up faster but is more stable and never boils over

Allan,
That's the same Xin Yong Shi output filter that I just bought for $68.42 shipped. Here's the link: https://www.aliexpress.com/item/This-is-a-gift-free-of-mechanical-parts-the-link-is-used-for-customers-pay-the/32602913439.html?spm=2114.13010608.0.0.0pHKMp
Shipping took 8 days which is ridiculously fast from China.
