    Frankly, I've never figured out why compressed air is so damn expensive.

      I agree, I bit the bullet many years ago and bought an air compressor, use it for so many things now, it's well and truly paid for itself.

        I bit the bullet

        I’ve been wanting to switch too. Recommendations? I mainly clean pc parts but also would like to spray paint

          Oh it's been a long time so don't know what's out there now. I know it was the cheapest unit at super cheap at the time, and i bought a longer hose from a market, plus a water separater thing as I was using it on electronics.

          I imagine you'd want a bigger one for painting, to have a bigger tank for reserve and a bigger duty cycle. I only use it in short bursts for cleaning computers, pumping up bike and car tyres, sports balls, air bed, pool toys etc.

          I use my 36v Cordless Makita garden air blower… only 5 secs needed…

        Compressor with tank?

        Thats one idea, but air has moisture in it.

        I want to try hooking up a Co2 bottle to a spray nozzle. Something like a soda stream bottle would be portable enough to use and have heaps of pressure.

        which air compressor y'all suggest?
        esp for Electronics does it make a differnce?

      The air in there is very hard to get, it’s very pure.

      They have to get the air specifically from the depths of the Amazon where there are lots of poisonous snakes and cannibals

      Dangerous business, but only the air from there will do

      Well, that's because it isn't compressed air.

      If a can were filled with compressed air, one of two things would happen. either it would run out super quick or it would need to be made with super heavy wall thickness. When you buy this stuff, you'll note that the can is full of liquid. The puny cans aren't designed for the kind of pressure that would be required to hold compressed air in liquid form.

      So then, what am I buying?
      Well, you're buying a blend of refrigerant gases. typically difluoroethane and tetrafluoroethane. Similar to what you get in your air conditioner. These products are great for this purpose because they can be compressed to liquid at around 70 psi. The can required to hold 70 PSI can be puny. As you release the gas from the can, some of the liquid in the can undergoes phase change to it's gaseous state and a constant pressure is maintained throughout the life of the can. Awesome.

      However, THESE ARE BAD FOR THE ENVIRONMENT.
      From google: releasing 1 Gram of R134a has the same effect as releasing 1410 grams of CO2.
      Most HFC gases emitted to the atmosphere today have 100-year [global warming potential] ranging from 100 to 14000, which are many times larger than CO2,” National Oceanic and Atmospheric Administration (NOAA) researcher Stephen Montzka

      What about my other sprays…? Sprays are probably bad.
      There is usually a small amount of a HFC inside any spray pack which maintain constant pressure throughout the life of the can.
      There are some environmentally friendly alternatives, some companies use them. As consumers we can't know who.

      This stuff should be banned; spray pack use should be limited. We've come so far since CFC gases such as R12, but we've so far to go.

      Good news though, look up how the ozone layer is doing currently.
      Cheers.

        it would need to be made with super heavy wall thickness.

        Scuba tanks hold 200 bar. For liquid, you need about 3,000 bar.
        I've never heard of anyone doing that. You'd need some very exotic construction techniques :-)

        This one contains the old now obsolete refrigerant R152a . Perfect for re gassing an old R12 system. The one HN sells has the current R134a gas many cars use. Perfect also for your trapped myna birds. It has caused numerous deaths. Amazing how Bunnings gets away with this. If you were a refrigeration installer you would typically need 2 licenses and still have a hard time even finding it. Oh well the WD company, at least their Share looks like a good buy…

    Used these to clean computer components… Not the best.

    The liquid that comes out (by design according to the can) can freeze dust in place.

    •  

      If you have a lot of cold liquid is coming out of the can, you're doing it wrong. DON'T shake the can like you would for a normal aerosol. Move the liquid inside as little as possible. It should just be blowing out air/gas.

      •  

        Nope read the can. The liquid is supposed to come out so you can see where you've sprayed, it's basically propellant but due to the temperature it can freeze the dirt on.

        It's literally written in the can.

        •  

          Are you sure about that?
          Read the can.
          "Hold can upright all times. Spray in short bursts. Do not use on live electrical equipment. Liquid content can cause frostbite."

    First they bottled water. Now they've canned air. What's next?

    Really weak and not worth the money. I purchased an electronic air duster on amazon thats 100x better.

    I bought a $25 shop vac from Bunnings and use the blower function to clear out dust from my PC.

    Works WAY better than these expensive cans of air.

    I use a brush, 15-20mm diameter to push dust'n fluff to the side and vacuum up the detritus.

      These are really good!

      I’ve had one for years also.

      But they are not as powerful as the compressed air can or the Milwaukee vacuum that I linked up earlier.

      Great tool, but not as strong.
