Hi guys,

Just saw this deal, seems pretty good coming from Bunnings, not sure if anyone is familiar with this brand? I reckon 2HP would be good enough for automotive works on passenger cars?

Good thing it is oil free so one less thing to worry about. The air tool range is going for quite cheap too, $16 for 10m hose, $18 for tyre inflator. Ozito 24L 1.5HP is also $99. They call it a run-out

While stock lasts.

    The 11L and 7.5L models have gone down in price too.
    Time to buy!

      I think that one is only half a horse power

    no mention of lpm or cfm, id probably steer clear of it for air tool use. for hte same price they do http://www.bunnings.com.au/ozito-24l-1-5hp-compact-air-compr… but thats still only 4cfm which is tiny. it all depends on how much you are going to use it really.

    • Azn310 on 24/07/2014 - 19:28

      Oh, yeah it did mention for very light use, tyre inflation and dusting and the likes. Oh well, back to the hand wrenches and ratchets

    • jdas on 24/07/2014 - 20:53

      Worth mentioning that the Aldi one also includes a hose and a set of accessories like blow gun, paint sprayer and tyre inflator.

      Crikey, I paid full whack for mine…. Grrr…

    Absolutely no use for spray painting. Useless for die grinder, anything that requires continuous flow of air for more than a few seconds.

    Would be perfectly fine for tools that are used intermittantly like nail guns. Also would be fine for inflating tyres (but noisy and too slow to initially pressurise for just a single tyre).

    Fine for bursts of air to clean out PCs etc, but maybe only 10-15 seconds of air at high pressure, then have to stop and wait for it to pump up again.

    Overall not a bad size, but not really a particularly cheap deal.

      LOL ok, maybe I should just delete this post in case someone gets misled into buying these

      • shmahoo on 25/07/2014 - 08:59

        that's OK, no-one on OzBargain ever suffers buyer's remorse!

    • greenie4242 on 24/07/2014 - 20:18

      2HP is no use for spraypainting, or rattle guns. You really need to look at large tank high CFM (Cubic Foot/Minute) numbers for that stuff.

      This little air compressor in the deal would be OK for inflating tyres or cleaning out dust from computers, maybe inflating large kid's toys, air mattresses, kayaks etc… Can't think of much else.

      • Azn310 on 24/07/2014 - 23:05

        Thanks greenie, so whats the ideal CFM? Guys above mentioned the Aldi one, which states 7.8 CFM on the label. Is it good enough for air guns and the likes?

          so whats the ideal CFM?

          how long is a piece of string?

          its all to do with what you are going to use it for, but mostly the larger the cfm the less it needs to "work"

          imagine if you only had 4inch long legs, or 7.8 inch long legs… or 16-18 inch legs… and you had to run up a flight of stairs…. the bigger the compressor you get the less it needs to "work" to do the job you are doing.

          i originally bought myself one of those little 7'ish cfm ones just to run air tools, it did ok but didnt last very long before it was pretty much burnt out, i then spent about a grand for a around 18cfm one that is pretty much a "workshop size" one caus i did a fair bit of die grinding and spray painting.

          for a rattle gun and air ratchet you can get away with the little (5-7cfm) ones, for a bit of spraying and some light die grinding you want to look more around 10-12cfm "proper" workshop type compressor, for some more heavy die grinding and sand/beed blasting (and ceramic coating that i now also do, heat proof/friction less stuff) you want something bigger like my 18cfm with at least twin cylinders.

          hope that makes enough sense, but basically bigger is ALWAYS better. an 18cfm can do anything and do it with ease, a 4cfm can also do most things, but you end up using it for a couple of seconds and waiting minutes for it to pump back up again before you can keep using it

          edit: also the more it works the hotter it gets, the hotter it gets the less dense air it can compress, when the air goes into the chamber at the bottom it cools and contracts so your 7cfm compresser only manages 7cfm when its cold, once it heats up its probably more like 1/4 of that. the bigger the compressor the less it works so the more cfm it can keep doing for longer. with my 18cfm compressor it can pretty much be used all day constantly and still keep pumping close to 18cfm, a little 7cfm doing the same job will probably be pumping more like 1 or 2 cfm if your using it once it gets hot

          so whats the ideal CFM?

          The ideal CFM of the compressor is the smallest amount that meets the requirement of your most demanding tool.

          A larger tank gives more "buffer" so the CFM of the compressor can be lower than the tool, but that means you cannot use it continually.

          For example, I have a 2HP 40L GMC cheapy. Spraying old-based stain (which is thin like water) onto treated pine retaining walls I reckon I could spray for about 5 seconds. Then I would stop for about 30 seconds for teh air tank to re-fill.

          That translates to: "You need a LOT of air to do spray painting". Nosdan's post is more technically correct than mine.

          However I can run a huge nail gun and fire 20 or maybe even 50 x 4 inch nails between tank refills, and there is no need to stop working while that happens. So the cheapy compressor easily handles that.

          For pumping car tyres they are OK, but too noisy and slow for bike tyres (quicker with a decent floor pump)

          These little "hobby compressors" are just toys. Handy, but useless for any form of serious work.

          after owning and using various different compressors over my time i have to completely disagree with taht. your comment is simply the "smallest cfm/compressor for the job" not the "ideal cfm/compressor". the ideal compressor would be the largest one you can afford/store for all the reasons i have already listed above.

          to put it another way, "whats the ideal way to have a car to fit 25 people" and your answer is a mini :)

        • Azn310 on 27/07/2014 - 03:35

          @nosdan:
          Thank you so much for the details from your experience guys. Nosdan i know I could always count on you on these stuff lol

          I only do garage DIYs, small car jobs so an investment in a good compressor (and tools and maintenance) might not be worth it.. A cheater bar and some grunting / swearing from time to time doesnt hurt :)

    Why do we still use HP? its so imperial.

    • llama on 25/07/2014 - 02:37

      Because that is how they rate the MOTOR

      It has nothing to do with the amount of performance, it is the power consumption of the motor.

      You could use watts… 745.699872 Watts per Horsepower. So this is a 1,491 Watt compressor motor.

      But nobody would think that was impressive, because it means nothing. HP is far more mysterious.

      • NosDan on 25/07/2014 - 13:53

        generally speaking HP is the physical rotational power output of an electric motor, watts (or kw) is the electrical input required for the motor from in this case your home power socket

        xxx kw input does not equal xxx hp output due to things like difference in friction and efficiency of the design etc.

    I had a 1.5HP 8 Liter oil free compressor before, just to blow out dusty PC and vacuum cleaners. It was darn annoying and frustrating to have such a small tank because you basically sprayed all the air out in around 5 secs and had to wait another 5 secs for the tank to fill and get more pressure again.
    Even for light work like cleaning, wouldn't anything recommend less than 2HP and 20 Liter tank.
    The accessories like hose and tyre inflator seems expensive when you add them all up, Super Cheap Auto usually have catalogue specials which include toolkit and hose.
    I recall Bunnings selling a Spear & Jackson 2HP 24Liter compressor for $88 normal price earlier this year.

    • Azn310 on 27/07/2014 - 03:38

      This is probably the reason Bunnings want to clear these out. 5 secs is like rubbish! Why would the compressor company makes something looks so professional but works like a giant piece of toy..

      • NosDan on 27/07/2014 - 20:45

        Why would the compressor company makes something looks so professional but works like a giant piece of toy..

        this is a little out of my experience (i have always needed bigger not smaller compressors) but i believe things like air brushing only needs a very small compressor. and maybe things like spray tanning? im sure there are valid reasons for such a small compressor, just not for your average back yard mechanic

        edit: oh, and as said above if your just using it for blowing out PC's etc it would also be fine caus you usually only use a couple of seconds of air at a time. its a pain using mine just to blow out a PC caus it takes quite a while to pump back up if ive not used it in a while.

    My mate owns a computer shop and has this exact compressor to clean PC components - rubbish! The pump is almost constantly running coz the tank empties so fast. I'd stay away from this one.
