Anybody using a Tsunami water separator with their compressor set up?

Jump to latest Follow Reply
Great idea/find and we need to something like this at this price! But this is not a high-pressure filter.  I really liked the Tsunami technology video but specifications for that separator say max pressure 250 psi. So I called the seller, who called the manufaacturer and emailed back this unfortunate information: "I received a reply back from my technical guy at Suburban, the manufacturer of Tsunami products. He said that Tsunami product won’t handle 4500PSI. If you needed something like this, they can design this but their volumes will be high, and the cost would be through the roof." I suppose that she meant to say volumes would be low and cost high. I could call Suburban directly and ask them "how high". We could try to do a group purchase. How many do you think we could buy?

The Tsunami is a fancy (compliment - it is an improvement) coalescing filter. These are used to remove water from low pressure applications. Its a great addition if its used to feed the output from a shop compressor to a Shoebox.

But I think to protect your investment in corrosion sensitive expensive air guns, if you have the choice you are better off using a molecular sieve on the high pressure output side of your air source. Bottom line: coalescing filter on low pressure side does not dry air enough for high pressure applications, but will help protect your Shoebox. There is no need for a novel high pressure tsunami water separator, because better and more economical alternatives exist. These already come standard on high end compressors (which also have a coalescing filter after the 1st compression stage), and Joe B sells as an aftermarket molecular sieve.

Thanks Regal. I need more education. Am I correct that this water squeezed out during high pressure compression is about a quarter of a cup on a scuba sized tank? (A product of air being compressible and water not being compressible?) So what does the molecular sieve do with that water? If it doesn't have drain, don't you just have the same saturation problem that you do with a descant filter? A coalescing filter with a drain has the ability to dispose of the liquid. Thanks for your help.

Volume of H2O in a scuba sized tank of compressed air depends a lot on relative humidity at start (e.g. Louisiana vs Utah etc). A coalescing filter is for air that's just been compressed and is only at a couple hundred PSI. At that stage the compressed air has tiny droplets of water and oil in suspension, and the coalescing filter causes these to condense into larger droplets, creating a liquid phase which you then dump. A molecular sieve is for 'polishing' output at high pressure, but eventually the beads become saturated, and cartridge needs replacing; they are pretty inexpensive. That's why dive shop compressors (which is what high end air gun compressors are based on - basically the same) have both types of filter. Also, to do its job a molecular sieve needs to be at high pressure, which is why you have to fork out $ for the container and valves; the media is pretty cheap.

Your welcome Looknup,

This thread is progressing along a line that's been discussed several times before on this forum. Shoebox Freedom 8 is a really amazing, clever design. But once you factor in the need for a shop compressor (if you don't own one) and filters to dry your air, its starting to add up $. I'm guessing that if you fill rifles directly, or perhaps better a small tank (like a guppy from JB or its equivalent), you are still ahead.

I've been filling using nitrogen for the past 2 years, but my source is about to go away, so I'm really interested in the various ways of filling, from Shoebox to Daystate, Airetex etc.
