So normally I get these for about $10 on ebay (and thats the price on good guys original) but these are on at $5 and no shipping if in store
Good for getting dust out of your computer
HFC free if you are into that green environmentally friendly stuff
Extension tube for precision included
Postage difference outweighs the 2% by far.
Or pick up and collect
Out of curiousity, how long does one can last for? 5 minutes? 1 hour?
You generally dont hold them on, the cans get REALLY cold when you do.
Id guess probably 5 minutes solid though.
I think even 5 minutes would be very optimistic. The little 150ml cans office works used to sell could only give approx 30 seconds of continuous high pressure output. They'd dribble out low pressure air for a bit longer, but it wasn't useful.
the cans get REALLY cold when you do
And more to the point, any longer than a 2-second burst and they will coat whatever you're spraying with white propellant residue, which is not good for sensitive electronics, for example.
nice one :) picked up 3
$5 for a can of air sounds expensive to me
To clean CPU, this is a good investment
A true OZBargainer would huff and puff :D
… Just like the big bad wolf.
Can't you just take your computer to the servo and use the air hose there? Remind me to borrow a shopping trolley so I can push it there.
@Stingo: Good thinking. I wonder if you could refill the empty air can that way.
Maybe you could use a bicycle pump instead
It's not actually just 'compressed air', it includes several solvents and byproducts of pressurisation, mostly hydrocarbons ultimately from petroleum. People just call it compressed air because all these solvents are volatile and largely disappeared without a trace after use (although the hydrocarbon aroma can often be detected).
I'll bite. Why not just use more air rather than adding an additional propellant. Of course, you could just be talking about the air itself from some poor city without pollution controls which could well contain every chemical known to man and a few unknown ones (or is that the water?)
I would love to hear about the "byproducts of pressurisation" because it's sounding a lot like a meaningless hippy phrase such as the hydrogen dioxide scare. Dioxide sounds so poisoness lel…
Also why would they add pointlessly add solvents when there is no need to?
Yeah, OK. Not trying to get all "toxins" and "mucoid plaques" on you - I don't quite understand how the propellants in aerosol cans work. But the cans do contain oily substances (it says "Propellant: Hydrocarbon" on the back of every can made since CFCs were banned). I think it's because maybe it can regulate the spray better, rather than being explosively powerful at the start and then tapering into nothingness. The answer can probably be easily googled. But my point is, it's not just air in those cans, it's other gunk too. Don't believe me? Spray some on your hands and smell them. It doesn't just smell like air, and you have some grime left over.
Also, the poison you're referring to is 'dihydrogen monoxide'. Hydrogen dioxide could mean H2O2, or hydrogen peroxide, a kind of bleach which can be dangerous ;)
@Meconium: I think maybe you need to get off the idea of adding pointless crap that's bad for your health lel. Propellant means the gas used to eject whatever is being sprayed as far as I know.
It's probably the same gas you spray yourself with everyday if you use sprayon underarm deoderant. I hate to break the bad news to you but you've been dousing yourself with hydrocarbons for years.
Use a straw
That suggestion blows
Freezes my lips every time
A rolled up $5 note works better.
a rolled up $1 note works even better. I'm no cashier so don't expect me to have more than $1 cash on me.
@jubba:
$1 note they stopped printing in 1984. And only worth 1/5th of a $5 note so much more affordable.
@imcold: Depends on the condition of the note. There should be collectors looking for this and should have more than $1 value. Not sure if it is higher than $5 though
How much force do these thing generate?
I bought an excellent one years ago called "Jet Air" or something like that. It had a bigger nozzle and really blasted the dust out. I bought the Dick Smith one and its a bit weak in comparison. More like a "puff" of air.
$40 postage for 3 of these to rural NSW
eBay store generally has capped postage. Link is in the comments above.
I usually just use the Vacuum cleaner for my PC ;) I do NOT recommend this:
http://www.pcgamer.com/should-i-vacuum-my-pc-ask-pc-gamer/
"Nosterex recommends a leaf blower, which I think is hilarious and will definitely try."
Sound like fun, but I have not tried my leaf blower yet. Maybe I can do the carpets and floors inside the house with this as well? Leaf blow the dog and kids…mmmmmmmmmm
vacuum creates static flow. make sure you put sticky tape on processor & graphics card fans.
https://www.google.com.au/search?q=static+flow&ie=utf-8&oe=u…
What?
Perhaps you meant static pressure (which still doesn't make any sense to me but at least it's a phrase that I know the meaning of) …
bit early to start your class sir :P
So can't use a Karcher? ;-)
Yes you can. Just tape it all up first :p
Yes, you could use a Karcher but only if you fed it demineralised oil, not water. If you do then please shoot a vid, post it on YouTube and put the link here :)
How about a vacuum to the back fan of a computer (in my case a TiVo) ?
Would having the computer (TiVo) on at the time keep it earthed & less prone to static electricity?
I'm not an expert (electrician).
Should be fine on the back of the TiVo. Leave it plugged in and/or on.
Would help if it is under warranty. Just in case you stuff it (not likely).
Static would be most harmful to RAM/Cache Memory/Hard Drives.
Backup Backup Backup !!!
I don't think that it would get much dust out of the fan thou.
Computer dust sticks to the fan's. I use a toothbrush for these.
Thanks meniac, will give the TiVo the toothbrush then vacuum treatment, after taking a photo for backup purposes :-P
Are these good for getting rid of sensor dust?
It'll get rid of it the dust… You'll probably need a new camera though.
So you're not supposed to use these to clean the lens on a camera?
Lens? Maybe, sensor? Absolutely not! I wouldn't risk either. Get a rocket blower for basic camera gear dusting
Never use any aerosol to clean the sensor - heaven forbid
Thanks guys.
Ever heard of an air compressor?
$5 is not cheap, unless you only have a one-off job.
You do know that there's moisture in an air compressor tank? Hence why there's water when you release the compressed air from the tank when you're done. But I guess you don't have one cause you'd know this already… :)
You are right, i don't have one… i have a fleet of them. there are ways of trapping any moisture.
Did you know this air in this branded can is not magical special air?
Feel free to keep using low-end disposable products, no problem to me.
You do realise that the moisture has left the air if it's inside the compressor tank I presume? That means it's no longer in the air stream.
You do know that there's moisture in an air compressor tank?
And most of these compressed air cans blast out propellant residue, especially when not in a completely level position.
Very poor value, buy yourself a 240v high volume air pump (air bed ones) they are excellent for cleaning computers, lots of air and you never run out! Had mine for over 10 years and bought it for $25 back then. Does an excellent job at removing dust.
Link?
…to 2005?
Hot Tub Time Machine!
but that could cause damage due to the lack of anti-static that those cans have in them
don't you guys this thing is massive rip off? I could hardly use it more than 10 times, and it's usually 9-10 a bottle….i'd rather just a good vacuum to clean my keyboard..
There are things you shouldn't vacuum, computer internals for example.
After years of using both a vacuum cleaner dusting head and a "air gun" type of thing (attachment with a trigger that you depress to release compressed air through a nozzle from a commercial air compressor) on my PC I'm yet to have any ill effects that I know of.
Wouldn't recommend it as someone else has already surmised ;)
I know I'll be continuing to not buy compressed air right up until I do have a failure from this type of cleaning but 25 years or so has passed so it's looking less and less likely …
Why clean keyboards? Weren't they free after Microsoft cash back..?
400ml of air equates to less than 0.5g, therefore the unit cost of this air is over $10000/kg!
Really? If it was really 400 ml of air, then the air pressure would be the same as ground level atmosphere.
If that was the case, if would hardly be rushing out to greet us every time we pushed the button.
Besides think of all the little men used to carry all the air molecules and cramming them into the can. Gotta pay salaries somehow.
Maybe they use a propellant, compressed air, politicians, Blazing Saddles beans?
Everything that is used to package the air costs more than the air you are buying :D
lmao
Do you guys recommend this for cleaning a keyboard? Abit too paranoid of pulling off all the keys and too lazy :P
you could i guess, but generally i only use canned gas to clean inside of computer case
good for cleaning food in between teeth?
Won't this just blow the dust further back into the vents on my laptop?
Computer case, aka desktop. Don't do it to an unopened laptop. Unless you unscrew the laptop casing and blow the dust out that way.
Thanks JahjaMan. That makes sense.
Kmart sells these for $5 every day.
Heres your ozbargain medal of honor
Have used a standard air compressor to clean PCs for the last two decades. Haven't killed one yet.
As I was saying … it's noice having the inside of your PC looking like you bought it yesterday again :)
I like the dust. Its my friend…
Actually speaking of dust I was realising how dusty all my shit is last night. Time to get the air compressor out again.
Not if you live in a Mr Fluffy house, it's not.
Damnit. Out of stock.
mubd1234 says he saw them at kmart, you could try there, although down in victoria I've never gotten the chance to see one.
I reckon the price clearance is because they put it in mobile phone accessories
