rebranded hydrovane?

[Henrik]

I've just picked this up on ebay:

Doesn't it look just like a hydrovane?

It's really quiet, perfectly possible to hold a normal conversation next to it when it's filling, and it only takes about 3 minutes to fill (not sure what PSI it goes up to - forgot to check).

doesn't look much like my hydrovane but will be quieter than normal as its a rotary pump

 

[Henrik]

ah, i thought rotary = hydrovane

 

[knoba]

Doesn't look like mine either...

 

[madkayaker]

hydrovane uses a turbine pump

 

[Henrik]

ok, it's probably not a hydrovane then

Never mind, still chuffed with it. It's apparently 8CFM FAD from 2.5hp.

 

[knoba]

Looks nice... water trap (condenser) looks like a nice bit of kit too...

Well done!

It's a dentist's back up compressor, quiet so the noise doesn't drown out the sound of my screaming Details on here. According to that it's about 8cfm at 75psi.

 

[Henrik]

Sounds good

Only bought it to be able to use a plasma cutter at some point, but i feels like a solid piece of kit, so migh even try to get some air tools now

 

[knoba]

Yeah... go air-tool mad Henrik, only... leave the dentist's drill out of it ...eh?

Any air tools, in particular, that take your fancy?

As others have said it's not a Hydrovane. Looks more like a 3 cylinder Radial. Nice find, esp with the dryer fitted. Have fun

I suppose an impact wrench wouldnt go a-miss, and hopefully it should be able to run a small spot blaster, and (optimistically) a small die grinder and a cut off tool. Will have to wait for a while, though... Saving up for a collet set for my mill...

 

[knoba]

I used a 1/2" drive impact wrench, for years, until I discovered the 3/8" drive. Lovely little thing, so nimble, light & quick... amazing the amount of power it has for it's size (over 300 ft lbs). Hardly use the 1/2" at all now.

I'd love a mill... and the space to put one!

 

[Shox Dr]

Sorry to tell you, all of those tools are very heavy on air. The Free Air Displaced (FAD) is between 25% to 30% less than the quoted CFM, and it's FAD that counts.

I'm not saying it will not run them, but you will be waiting for the compressor to play catchup all the time, buy your tools wisely and it will make a vast difference, to the consumption of air

 

[Henrik]

But this one is 8 cfm fad at 5 bar according to the spec - is that still too small?

 

[shenion]

Impact wrenches really want 90PSI. 75 is a bit low.

It will work, but will not have full torque.

Nice find though, should be real clean/dry air.

 

[Rick]

It will still do 90psi+ of pressure, its just the CFM is quoted at 5 bar which is probably when the compressor actually kicks in. I think it'll be great actually at running most tools for intermittent use. 8 bar is actually pretty good, especially for the HP it is.

How much did you pay?

Avoid cheap impact guns. There terrible. I've just bought this. 1,190 ft lbs of torque!

 

[madkayaker]

nice

 

[knoba]

They are nice! I've got the same (MG725) as Rick, as well as, the 3/8 drive model (MG325 - 425 ft. lbs).

Those figures are break away torque though...

They both run on my little compressor fine.
