While canned air works great for removing dust from electronics and is very portable, it has its downsides — it’s expensive, and if you use it for more than short bursts it can freeze and stop spraying until it warms up again. Metro Vacuum claims there DataVac Shuttle vacuum/blower can replace those cans of air relatively cheaply.
The 8oz Shuttle uses rechargeable batteries to operate for 40 minutes, or it can be plugged into the AC adapter if the batteries are dead. Measuring less than 7″ long, Metro claims the vacuum/blower is powerful enough to “clean dust and dirt from computers and office equipment.”
The Shuttle comes with the charging station, four rechargeable batteries, 110V AC adapter, micro extension tool, micro dust brush, and blower adapter. You can find the little vacuum/blower for as little as $20.
