Aldi air compressor

I would have to agree with oldcoolone's comment.

Just because they look similar / the same on the outside doesn't mean they are the same on the inside.

A quick check would be how much it weighs.

If it's a 40mm piston they are normally 72L/m or 92L/m with the 92 L/m normally just spinning faster. The twin heads are mostly all 40mm cyls and generally working hard. The newer Single 60mm ones (last 5 years or so) will generally outperform the twin 40's both in inflation time and run time.

We have seen a lot of different branded twin 40's that said there was a thermal cut-out installed but when pulled apart it wasn't there.

Likewise with the newer 60mm ones, most have "heatsink" that has horizontal fins, the problem is that so far all the ones of these that I have seen with horizontal fins are actually a plastic heatsink. Our BP160 has an aluminium heatsink, and we purposely had a different looking heatsink made to the factory standard.

Most Compressor comparo's that I have seen, normally only check inflation time. I don't recall seeing one that tests the various compressors on the market over an extended period of time, eg to equate to the use of compressor over it's expected life-time.

Likewise I don't recall seeing one that has pulled the units apart to check if the crank is plastic or metal, does it have ball bearings or bushes on the crank, or the quality of the actual unit, actual size of motor, and magnets etc, overall weight etc.

So whilst a compressor may have a quick inflation time when new, what's it like after a couple of years use. What about spares and support outside of warranty etc...

Now you could say that I am biased because we sell our own units, but we have had a extremely good run with ours since we introduced them a few years ago. At the end of the day customers will buy what they feel comfortable with, some shop by price, some shop by brand, whatever the reason people purchase a particular unit as long as it meets their needs and while it doesn't let them down they will generally be happy with it.

Sometimes really cheap units are really good value, sometimes they are not, likewise for more expensive units.

How do you use an air compressor in anger? :)

You don't want to know!

Fair point. Let's just say that it means airing up your own 4 tyres, then starting on the remainder of your mate's 4by tyres since his compressor is about 1/2 the speed of your own :)
