    Air compressors - belt drive vs direct drive

    Anyone got any thoughts on this?

    I've noticed that the belt drive ones seem to be more expensive so I'm guessing they are a better system.

    Supercheap have a small direct drive one on special but if it won't be up to the task of light shed work, it isn't much use.

    From my limited knowledge the direct drive ones have a smaller capacity and rev higher to make up the rated figure while the belt driven ones are the opposite. For average home use a decent sized DD one will be fine but the really small ones are marginal at best.

    Noise would be a factor, especially firing it up at night in suburbia.

    When I say small, the DD ones are small when compared to the belt driven ones. It would probably suffice, but I might try chase down a cheap belt drive one.

    What tools do you wish to run from it?

    FYI I have a decent air compressor, but prefer to use my battery rattle gun over the air one. It's just so much easier to use anywhere in the garage. Same goes for drills.

    It'd be rattle guns, ratchets, drills and maybe the odd stint with the die grinder. Painting may be an option as well some time in the future. So just general shed stuff. I normally use air when working on cars as that's what I have always had access to. Rattle guns and air rachets make gearbox removal much quicker. The air drills are more compact, shorter and lighter than battery drills which is a big plus when working in tight spots lying under a car.

    Bigger the better for all that stuff, specially die grinders and air tools. Forget the small DD's.

    A small direct drive one will be no good for any of that. They are noisy and produce shitloads of heat trying to do their job.

    Get a 6cfm belt drive. Then you can do everything including spraying from it if ut ever tickles your fancy

    Belt drive for sure. Spend a bit extra now and you will keep it forever. Plus it is easy to service if you need to replace the pump or motor.

    OK, time to start looking for a decent priced belt driven compressor then. I was hoping the DD would be passable due to very attractive price, but like everything, you get what you pay for.

    I have the biggest belt drive one that Supercheap make. Went well for 18 months and now a bearing has gone in the motor so it sounds like hell.
    The tank and attachments are all good, is there anywhere you can get motors for these? Have the $$ to spend now for a good one.

    The 2.5HP supercheap compressor is so noisy! I regret buying it.
