I will also add my name to this, I have informed SWMBO that oxygen is good for hay fever....(may not be true)

I was in touch with an ebay seller before about these lads below: (is this the same as yours CH?)

http://www.ebay.co.uk/itm/Oxy-Turbo-Oxygen-Disposable-Gas-Cylinder/161063167235?_trksid=p2047675.m1850&_trkparms=aid%3D222002%26algo%3DSIC.FIT%26ao%3D1%26asc%3D11%26meid%3D9155680382373718151%26pid%3D100011%26prg%3D1005%26rk%3D1%26rkt%3D5%26sd%3D130904157295%26

16.50 GBP is the best they can do on shipping.  I cant find any online seller in Ireland selling them.

It says on their ebay page that they only deliver to the UK mainland. It seems to be same for other suppliers in the UK I've come across - probably due to the dangers involved in using oxygen. Does anyone know where else we could source the oxy turbo bottles?

[Shane Phelan]

Nothing stopping us from using parcel motel and then when the package is too big/heavy they deliver it for €15.

Or when you are saying mainland, that excludes the north?

[Dr Jacoby]

True, though some of the suppliers only supply the UK mainland, excluding Northern Ireland. Others say they will ship to Ireland but for an additional cost. Parcel Motel really does rock

[Shane Phelan]

Just checked their website, we can actually avoid the €15 if its collected from their depot and under 35kg.

[Hop Bomb]

Its the crowd in Dublin who said they'd do a discount on the oxyturbo bottles. 

Re: that ebay link - I mailed the seller & that was his best price for shipping as it weighs 1.5kg.  Its irrelevant anyway as we can get them from Dublin (wholesale welding supplies)

[Metattron]

CH, where in the north do you get the oxygen from?  Lots of places doing regs for them for around £20.  I take it this is the type of filter you were looking for:

Wholesale Welding Supplies sales guy rang me & will have a quote for me in the morning on the oxygen & the regulators. He told me the disposables are 137 bar (do your thing Will

Oxyfit got back to me with a quote on their 2 LPM fixed flow regulators (which should fit the oxyturbo bottles):

1 @ £110
3 @ £95
5 @ £90
>10 @ £85

Shipping to ROI is approximately £19.20

Uck uck uck me sometimes what u are looking is right under ur nose
Thank you so much for finding this

[Metattron]

Didn't answer the question though!

Aren't 2lpm fixed regs too much? From what I've been reading 0.2lpm for 30 seconds is what you want for a 20 litre batch. Too much oxygen will damage the yeast cell walls.

[Hop Bomb]

2 LPM regs are the slowest flow rate they do. You dont have to run it for a minute. You could do how ever many seconds needed to hit your desired ppm for your OG.

I posted this earlier in the thread re: lpm & ppm.

Here is some info courtesy of Dr.Jacoby via Chris Whites Yeast book: oxygen needs to be injected at a rate of 1 litre per minute in a 1.077 wort to reach the desired 8-12ppm. This time could be reduced for a weaker wort. ("Yeast", Chris White, p. 79) The best flow rate for a homebrewer is .5 or 1 litre per minute. So for a wort of roughly 1.045 you'd need to oxygenate for about 90 seconds if you were using a .5 litre per minute flow regulator. If you were using a flow meter set to 1 litre per minute you'd need about 45 seconds

Going off that with an OG of 1045 & a 2 lpm regulator you'd run the oxygen for 22.5 seconds.

Il probably just get one of those cheap flow meters from China myself. http://www.ebay.com/itm/Brand-New-5LPM-Air-Oxygen-Rotameter-Flow-Meter-Flowmeter-/150967186248?pt=LH_DefaultDomain_0&hash=item2326587348

My number 12 post was about right then if you allow 80-90% transmission rate
