5 Star Air Duster Can HFC Free Compressed Gas Flammable 400ml (Pack of 4)

I have been buying plenty of these for the past 2 years. There's a lot of air in there than first expected, at great pressure. Every can comes with a nice long hose/pipe which is also very flexible to redirect the blow in hard to reach area's - these hoes's are tied toe the can by elastic band or sometimes tape. I go through HFC Free Air Duster's a lot, mainly for computer's/laptops. They save time clearing dust in fans/grills/vents versus using a cloth for a quick clean, just be sure to have a vacuum nearby to get rid of the dust too instead of having it end up in the same room, only to be sucked back into the computers, or you could be outdoors. What's most appealing is the good quality product coming at a very affordable price versus shopping at the highstreet/large retail stores. Attach hose if required, Give the can a quick shake to build up more pressure, And Before using on intended area, Remember to give a quick tap spray away from surface/in the air to disperse residual liquid, then use as required, in an upright position. - If you do forget these steps and get liquid onto the intended surface, don't worry, it will quick-dry away in seconds with no marks.

I recently bought a small can of compressed air from Maplins to give my cousins laptop a dusting as the little fan inside was getting very noisey after a few years on the road. I paid around £6 for that can and it done the job perfectly! but the ONLY problem was, was that it was a 150-200ml can and even though my cousin paid for it - It wasnt exactly the greatest value for money. PC world was slightly better - 2x400ml cans but for almost £15. I really wish i checked amazon for a similar item before i went ahead and bought from maplins because these amazingly good value for money!! and not only that! you get 4 of them too!! Compressed air is great for many things, but since I do a lot of PC and laptop repairs - having a can of compressed air is a definite must! - some of the systems ive worked on is chocked full of so much dust as much as the sahara has sand. --- So if you want to keep your Computer or laptop working - remember to try and keep the insides dust free - buy these and just give the inside of your case a little blast especially around where the processor is - DONT FORGET TO HOOVER UP ANY LOOSE CHUNKS OF DUST AS IT WILL ONLY GET SUCKED BACK INTO YOUR CASE AGAIN! --- as for laptops - Just make sure its turned off and give it a few generous blasts where the vents are at the bottom or the side of the laptop. if your feeling brave you can take the bottom of the laptop off so you can give the fan inside a real good blast which should get rid of any dust for the next 6-12months --- REMEMBER TO TURN YOUR PC/LAPTOP OFF BEFORE GIVING IT SOME 'COMPRESSED' LOVE!!

This pack was a great price, especially when compared to the much more expensive alternatives on the market. This compressed air cleaned the dust from my PC effectively with no leaking / moisture, which can be an issue with this sort of product. This pack of 4 should last you a long time too if you are primarily using the compressed air for cleaning your PC. Note that the cans get very cold if you are using for a long time / spraying continuously, which will be made worse by holding the can sideways or upside-down. Try to hold the can upright and use in short bursts for the best results. The plastic hose attachment can also be quite fiddley to fit to the can. So overall, the product is very effective and great value for money, however, it loses a star for ease of use.

I use my Laptop intensive and for some reason I have to get it dust clean every 3-4 months or my temperatures are throw the roof. I will give you some numbers before and after (yes, I did note them down). Average usage after 1h (before using the compressed air) HDD 37C / SSD 44C / ACPI 91C / CPU1-4 76-81C Average usage after 1h (counted since first boot after using the compressed air): HDD 27C / SSD 29C / ACPI 46C / CPU1-4 39-43C Bench-marking with Intel extreme tuning utility. Maximum CPU temperature: - Before using compressed air: 103C (I guess it should have restarted... my max Tjunc is 105 though) - After using compressed air: 89C - After using compressed air while writing the review: 89C(guess 100% usage is 100% usage ... my mark is a bit higher as well.. odd) Even more amazing is the fact that I was using my laptop cooler (pad) before cleaning and I forgot to connect it while doing the after cleaning tests. I do not expect to get the same results after 2 weeks, but I do expect to get them if I use the compress air again: pain free, cheap... what more can you ask from this product? If you're like me and you use your laptop 8h/day for work and than chip in another 20 or so in a week... than you might need this as well. To be noted I usually clean my laptop myself, but my current one is just a pain in the ass and I prefer to give it to a professional cleaner to make sure I don't miss a screw or smt... so again... much cheaper to get this cans haha

Used it for dusting out my PC chassis (I would strongly advise against using directly on ESD sensitive components though) which worked as expected for the larger gatherings of dust, but the flow rate of air is lower than you would expect so just using the can is not enough for full cleaning you will need secondary cleaning methods. One can lasts for approximately 10 minutes, so not great if you will be cleaning PC cases often, I would recommend getting an ESD safe electric duster, in the long term it would definitely work out cheaper. In summary, works fine, does leave some freezing residue on objects so watch out for that. Cans are light on pressure, you will not completely removing dust with this more moving it gently from one place to another nearby, and each can lasts shorter than expected. Easy 3/5

Der Air Duster macht genau, was er soll. Staub von berührungsempfindlichen Oberflächen und aus schwer zugänglichen Bereichen entfernen. Ich nutze ihn vor allem zum entstauben der Elektronik und der HEPA-Filtereinheit meines Staubsauger-Roboters und bei meinem Desktop-PC. Man sollte beachten, dass sich die Spraydose bei längerem Dauereinsatz (Sprühstöße > 30 Sekunden) stark abkühlt, da sich das Gas im Inneren ausdehnt und dabei der Dose selbst Wärme entzieht. Der Sprühdruck sinkt in diesem Fall ebenfalls. Nach einiger Zeit der Wiedererwärmung kann es aber dann wie gewohnt weiter gehen. Mit abnehmender Füllung ist ebenfalls mit einem leichten Rückgang des Austrittsdruckes zu rechnen. Ein Erwärmen der Dose vor Einsatz ist aus Sicherheitsgründen nicht erlaubt! Es besteht Explosionsgefahr. Für mich ein sehr guter Haushaltswichtel, den ich nun schon seit 15 Jahren nutze. Immer wieder gerne!
