What did you use it on?
iMac chassis
… nice
I've used this multiple times over the years to clean computer components, speakers, dirty phone USB slots, etc… It has always been great. Make sure you always hold it vertically when using it and not tilt it around at all. You always tilt the object that you want to clean, not the compressed air can itself.
Sorry mate, not always possible. I’d like to see you move a 27in iMac around with one hand whilst holding a can in the other.
Edit: I will take your tip on advice for smaller items, ty.
I think he’s trying to say for the best results, if possible hold it vertical. Otherwise you may experience average performance, indicated by your original comment which had no context.
Do it vertically upside down for cool surprise :D
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
They aren't for eating…
Chocolate bullets?
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?
Yes, 21L 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.
That's why I fitted a water separator to my compressor.
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
In the absence of any other explanation, I'm willing to accept this as fact.
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 MontzkaWhat 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?
Sunlight
Some crazy guy already did, and called it a torch.
Bottled sound of silence
Earplugs
Farts
Stinkbombs
Canned air has been around for decades
I dare say well before mainstream bottled water was commonplace
dirt
Really weak and not worth the money. I purchased an electronic air duster on amazon thats 100x better.
Link please?

was $100 but i got $8 cashback at the time. now $110
im looking for portable/rechargeable plis
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.
Can you link me pls?
A Vacumm cleaner has blower function?
Shop vac has two connections, input and output.
Was very common in the old days
Not so common now though
I learnt this many years ago too. I went up market and I bought a Milwaukee portable/cordless wet and dry Vac/blower. It is so good!
I still keep a can of compressed air, but I rarely use it

It was $25 on special when I bought it.
Just FYI you are not supposed to use vacuums/electric suction for sensitive electronics.
It can easily generate static electricity to damage components.
Keyboards and such it's fine. But mobo and micro stuff it can damage and you might not find out easily
I use a brush, 15-20mm diameter to push dust'n fluff to the side and vacuum up the detritus.
Looks like the one Kmart sell for $8
Came to post this, not sure why the ozbargain community hasn't clued on to the kmart normal price being streets ahead of everywhere else
Just buy one of these. Never runs out and they give a good blast of air
https://www.aliexpress.com/item/32816031844.htmlThese 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.
Recommendations for cleaning built Lego sets? Paintbrush is too much work.
Garden hose :)
Top load washing machine, skip the spin cycle and then dry them on the deck.
Can I use this to remove corona virus?
no you'll just blow it away and it will become somebody else's problem! 😠
Thanks just in time to regas my aircon
Can I use it when I run out of toilet paper?
lmao $10 for a can of air just use a hair dryer or your mouth lmao
I use this to blast the gas holes in my Weber…..patience Grasshopper!
I use a garden blower vac to clean my chassis and my Xiaomi robot filter and it works a treat.
I need to know is this flammable because my wife said I'm not allowed to spray flammable aerosols in the house.
Everything has a flash point! Ask your divorce lawyer! Seriously there are youtubes, yes it contains acetone yes spray it into a bucket and you can warm up the house.
Used this today. It’s ok not great.
