How To Build and use the "Omni Booster"

Yes it works but you will lose gas and you have to stand there. Also you will get air in sooner or later.

This method was the upgraded version of allother methods known as "trash bagging"

Might be getting rid of my trash bag, got an adaptor from BN to Din.

I also have all the items in stock

This is how messy and yucky it can look and still save thousands of buckaroos


Notice the valve is still in and the silicone is overdone (just to make sure) I snipped out a bit of rubber inner tube and fitted it on the other side so people would never work out how its done.


It works in all positions


The nice and messy compressor room, where I spent hundreds upon hundreds of hours mixing gas for hundreds of clients. Note how the second stage has been stuffed into the hose. It is fitted with an adjustable band

Nice and simple design.

Have you experienced excessive compressor wear due to pumping He mixes through it?

Helium dose not wear the compressor at all. The compressor actually runs much more quiet and cool when pumping helium. After millions of liters, no problem at all.

Oh bt the way, while scavanging cylinders, you can disengage the auto drain if you have one, as the air is already dry this will save a lot of gas.

Shoot me down in flames if you like but a thought......

We blend nitrox using a nitrox stick. You feed oxygen in the top at atmospheric pressure and the suction of the compressor as well as a few baffles mixes it with air. This is compressed by the compressor into your tank. The nitrox mix is adjusted/checked by an oxygen sensor at the bottom of the nitrox stick.....simple and effective.

To mix trimix could we add another, helium, inlet and then a helium sensor at the bottom of the mixing stick? You could then use the sensors to adjust the flow of oxygen and helium to make your correct mix.

Or is this impossible?

Trimix training soon......

This is totally possible and also very effective for blending and topping up trimix.
You can make a stick with 2 sensors; one after O2 and one after the Helium. A friend of mine made a little Excel application to figure out which sensor readings you need for accurate mixes; both topping up or topping up to change mix.

The Omni Booster is really for a) scavanging gas from cylinders for reuse or storage or b) for topping up Js and freeing up other Js for rotation.

So if you made your mix with a stick and have 100 bar left over in 2 twin sets, you can free both twin sets and fill a 3rd for example.
Or if you have say 50 bars of 10/70 in double 18s, you can make a bottom stage out of it.

The optimum "Gas Shack" should have a trimix Stick and an Omni Booster as supplements to a PP blending whip.
