mini sport booster - can it be driven with higher than 10bar?

Brainx3 · 7th March 2008, 05:41

Hi,

Well, please do that and let me know. I have a power converter (110v - 220v) which I use to recharge my cordless drill battery which I bought from the US but the converter is about 60 watts, so if I got a compressor which is > 15 Amp then that would need quite a big converter to be used with. Luckily, my ultrasonic machine which I bought from China was 220v already

Hi Spyros,

Apparently, Haskel 4AG-25 Booster (AKA Mini Sport Booster) has a maximum air drive pressure of 150 PSI (10.34 Bars). I will upload the specs with this post. How did it go with DeWalt dealer today regarding the compressor?

Best Regards. Wael

hello Wael,

thanks for the info on the booster. i am dissapointed from the Cyprus deWalt dealer. he was a good and helpful guy, but did not have any of the compressors giving out more than 8 bar.

there is no demand for those you see, as he said. but he promised to enquiry and let me know by Tuesday. we may have to import from Germany as they have the 220V there. but he did mention something like " its going to be very expensive" and i was like

i told him i found it on the net for around 370 USD....but they are 120V...(ok, i didn't tell him the last bit)

i shall let you know. i somehow fell inlove with that D55145 compressor

Hi Outlaw,

The Haskel as mentioned has a maximum drive input of 10-11bar. After this it just vents from the over pressure valve, so no point trying to drive it harder. You could drive it from a HP shop compressor, but then you would need to regulate the flow and the cost of running a HP compressor to drive Haskel is a little silly.

Wael, i dont think the compressor you have ordered will be suitable for drive gas. As i mentioned before in other post you really want AS A MINIMUM 2-2.5HP compressor with a 50ltr tank and you want to be able to adjust the cut off and on. If the tank is any smaller(50lt MIN!!) then the tank will empty VERY quickly and you will be running strait from the compressor.

With a 2HP compressor and a 50lt tank once adjusted correctly and driving the Haskel to pump around 5bar/min of 100% O2(gas blender standard) your compressor will be running most of the time to keep up with drive gas consumtion. Any smalller and the compressor will have to run non stop and may not even be able to keep up with the HUNGRY Haskel.

Cheers

Granted I'm in Canada, and I'm using the Jetsam Baby Booster, but it too requires around 150 psi drive gas. I bought the Dewalt D55141 last summer and it has been working like a charm.

My gas fill set-up is much like you describe. I have one 80cf tank of "shop air" that I use to top up the diluent bottle as well as my suit gas, and one 80cf that I fill with O2 from my main K bottles and use for convenience. Filling an 80cf tank with shop air to act as top-up gas is pretty inexpensive (compared to using an 80cf as drive gas) and lasts a good while.

Then I found a sweet deal on an Alkin W31 compressor, and now I have a spare 80cf bailout bottle.

Cheers,

Hi,

Specifications of the Meec Compressor I ordered:

- Oil-Free
- 2.5 HP
- 16 Liters Tank
- 10 Bars working pressure
- 120 Liters/min
- 220v-230v

The compressor is very compact as you can see from the picture which I uploaded earlier and comes with 1 year full warranty and cost only about 110 Euros (999 SEK). I think that's the best deal I can get here since the Dewalt isn't available in this region yet. It's sold by one of the biggest hardware stores in Sweden called Jula. You can check out their website: www.Jula.se

I think this is more than sufficient for the purpose, anyway, I will try it once it arrives as it takes 2 weeks to be delivered.

Best Regards. Wael

Guys,

thanks for the imput, but do you also use filters, or just connect the compressor straight to the haskel? if yes, what filters, and how?

thanks.

Brainx3 · 8th March 2008, 08:13

Hi,

Well, I haven't used the booster yet but I would definitely use filters as well. There's a small filter which is sold by the German company Euro Cylinders for about 150 Euros. I'm thinking of purchasing 2 filters and connect them together by a manifold for extra filtering. Even though the dive center where I take air from has a very good air quality, but I'm personally very picky and want peace of mind.

Best Regards. Wael

Hi,

Just wanted to ask if you have found other filters which you are considering to get in order to use with your booster? I'm always open for better options.

Best Regards. Wael
