Thread: Information on a Cheap Air compressors

.....and the CFM @ pressure figures clears that one up once and for all as well!

thanks,

Mate, I have had to work hard to justify my tool purchase to my wife but who cares what anyone on the BB thinks.

By the way my compressor is even cheaper than yours and I don't care who knows.

I had an 20y/o old Sharpie 12cfm and the elec motor died,I ended buying a 10cfm 3hp from bunnings($399) and linked the pair up with all the water filters etc so its a bonus having a spare 10cfm to play with and I can get away with running an air sander for short periods at a time.
Downside is that your compressor is running longer to fill both tanks.
Might even lash out and get a 2nd one to make 30cfm.

So what's involved in linking them up?
Could I for instance buy another $97 one from supercheap and have a 4hp 45 litre monster instead of a 2hp 24litre toy?
No, I'm serious. Could I? Will it work? It is certainly a cost effective way out.

hovo
your air tanks would have to be connected with a larger connection than your discharge hose and have no restrictions in the line
Then your two compressore would cut in at diffrent times and pressures unless you had a lead lag pressure switching device
It is possible to buy an air tank and connect your compresser to that with a feed off the tank but your usage will still proberly be greater than your compresser output using a low cost compressor

Bottom line you can but the advantages would not be great , lead lag would be a problem and do you need it ie cost against end result
If you need a proper, say spray paint set up, then go to a proper set up not a fly by night coupling of two compressors .

Thanks mate, I thought it sounded too good (easy) to be true.
My cheap little compressor is fine for pumping up tyres and driving the brad nailer, so I'll stick with that.

reuelt.... did you actualy used all that gear on your compressor or you are just reading from the manual?

Because I have one just like that, and when it drives any nail gun even two at the time, it cannot drive an air nibbler for any lenght of time, not even enough to cut one sheet of colorbond fence, not even half whitout kicking in and stay on permanently, and the air flow provided in "direct" mode is not enough for the nibbler to work properly. Good compressor but limited to nail guns and pumping up tires and,,, not sure what else. Would hate to paint with it. May be with one of those mini paint guns they use to do signs.
Sand blaster?...must be joking.

Reuelt,
I would be interested to know if you have used your compressor for painting ( not necessarily the whole house) and what limitations you have found. I have seen a similar compressor 2.5hp 40lt for $128 which looks to be a bout the same as the arlec ( will have to check it out properly first)
and if it is good for nail guns /and a bit of painting /lacquer then I may go a get one . If not then I save a bit.
thanks

Bugger should have searched better before...according to other threads it should be ok....
Now anybody used /informed opinions of the el cheapo nupower compressor?
(fully understanding they are not trade quality)

Home hardware had a similar type compressor a few days ago for $89.

Home Hardware's one (green) is a rebadged GMC.

Check the manual in the box for proof!
GMC are not doing it to hide their name as far as I could tell, it was that Home Hardware wanted green ones.

I seem to fit this thread perfectly. I picked up an Arlec 2hp 24litre 7.9 cfm air compressor from Kmart the other day for $50 (they are trying to clear this stock). I wasn't sure about what I needed in the compressor but I want to run a finishing and framing gun. The price was too good. I emailed Arlec if it would run a Senco framing gun. They told me that it would depend on the cfm of the gun. What does cfm mean? I gather it has something to with rate of flow.

see title

Now anybody used /informed opinions of the el cheapo nupower compressor?

I have Nupower 2hp which has a higher upright compressor. Notice the new 2.5 BigW has a flatter compressor similar to Supa Cheap & Arlec compressors.

Very happy with my compressor which makes up air quickly. The only complaint is the plastic wheels which are meant for smooth cement and not gravel/stones. The new 2.5 has much better wheels. Would buy again, especially if the wheels have been improved.
