    Im looking at getting a half decent compressor in the near future.... I want it to be a quality and reliable unit that can handle most tasks including spray painting and what not...

    Roughly looking at spending around $5-600 on a decent piece of gear.

    A few in the trade tools range have caught my attention, I just need experienced people to make recommendations and clarify some differences.

    Like what tyoe of CFM do I need to do auto spraying?
    Whats the difference/better/worse between belt driven and a direct drive unit.

    anything else that comes to mind that would be helpful in deciding what to get would be awesome

    Cheers
    Niz.

    Awesome cheers for the response Nick..
    As I said I don't really know sweet F.A about compressors.
    One thing is that I'm not going to be using it hardcore ie: all day etc, so its not a great concern as I don't think I will wear it out overly soon.

    The HD300 is kind of just out of the price I really want to spend, I want to keep it under $600 ish if possible.
    The HD200 is the other unit I was looking at, just went with the direct drive one that is linked above because it was a lil cheaper, had a bigger tank and flowed more air p/m.
    Now that I aware of the actual pro's/con's of each type its easier to make a decision, on that note I will prob go down the belt driven path, but still not sure yet as I haven't looked at anything else from other manufacturers.

    Don't buy a compressor based on price alone. The HD240 is a good unit but not meant to be run all day.

    You should be looking at the RP16E instead. Yes, it is a 15A compressor, but when pumps and motors get to a certain size, they DO require more current to run. You cannot and should not run a 15A compressor off an extension lead, or file down the plug to fit a 10A socket. These machines draw ~12+Amps on load and even more on startup. Get a 15A socket installed by a professional electrician.

    .That said...

    I own the HD200 (cheaper pump & motor version of the RP13E) and it has done a full car respray. Ideally you need 15+ CFM to "comfortably" do a respray job, as anything less requires some time for the compressor to "catch up" all the time. The RP13E / HD200 would be considered the "entry level" backyard painters compressor. Its also the largest 10A belt driven machine that TT do. Anything above that goes to 15Amp.

    Belt driven machines are much more efficient, quieter and will last you a few more years. IMHO, the HD240 you're looking at is more meant for "onsite" usage by people with nailguns... Its a 10A machine which means that it can be used on sites that only have 10A RCD power. Its really made for the chippie with a ute who puts up fences or does lots of decking or framing.

    Please let me know which path you take. I won't go hard on you, but having sold compressors for a couple of years, the guys who bought the wrong ones brought them back melted, and the guys who bought the right ones for the right job - I never saw their machines in the repairs section

    If money is an issue, there is the HD300 (twin cylinder version) http://www.tradetools.com.au/Catalog...ductCode=HD300
    Otherwise, seriously have a look at the RP16EM http://www.tradetools.com.au/Catalog...uctCode=RP16EM

    A few more bucks, but the RP16EM is a triple cylinder and we all know that there is no replacement for displacement

    The man seems to know his compressors.

    if your looking for a cheaper option the 2.5/2.75hp supercheap ones arent bad as they can do most most of the jobs including painting. but not for everyday use

    Bought one today, ended up going the HD240.... only because of the amount of air it can generate and was more suitable to what I want to do with it, and it was the biggest one I could run off a 10amp power supply.
    I almost actually bought the HD300 but I didn't feel like getting a 15amp socket installed etc. the HD200 was a toss up also, but I wanted the bigger flow unit and I don't plan on doing any heavy duty work with it so I'm sure the direct drive HD240 will be reliable. Its not as noisy as I expected either.

    Fuck the cheaper option, buy the right tool for the right job, $100 might seem like a lot now, but ten years down the track when you've used your compressor every weekend you'll look back and realise that extra quality cost you about 2 cents a week... to own the better machine.
    yeah, sorry about the poor grammar.

    All i was saying was they are good for a few odd jobs if you are not going to use it heaps. If you want a machine for the long term, then yes get a proper one. But if i want to use a good machine i just go down to work (or a friends work) and use the industrial one which will do everything all day every day for free

    I'm also looking at a compressor and WAS looking at the super cheap option, but now that all has been explained about what to look for i'm definatly not getting a Super Shit one.
    I think i'll save a bit more and get the right tool for the job.

    Thanks guys.

    If you don't paint the bonnet and the roof at the same time. or paint the doors and guards off.
    You should have enough air to do your painting with a 1.5 - 2HP and a 50lt tank if you follow the 1.5 coat system.
    Make sure you buy a air regulator with a filter. Because you will get rust/water and shit from in side the cylinder tank hiding in your primer/paint just waiting to cause some damage.
