    Question Cleaning projectors

    Hi guys

    I'd like to know your thoughts and experiences of cleaning projectors. I've read that some people use compressed air but apparently you should use a vacuum cleaner? If a vacuum cleaner is the way to go can people recommend ones that are ideal. Also if your projectors are on a pole do you take them down to clean or are you able to clean them whilst still mounted?

    Thanks in advance!

    We use compressed air. Using a vacuum cleaner on any electronic items is risky to be honest, as you may end up sucking something up which you shouldn't. Not such an issue if you're doing an external vacuum on a projector, as there's no capacitors you could accidentally be sucking up but still.

    We do it in place, spray all the bits that need a clean, make sure all vents are free and clear and move on to the next one. Otherwise, what is about a 2 hour job becomes a 10 hour job.

    My technician does this now, with it being done termly. Keyboards, monitors and mice are cleaned half-termly (which reminds me, need to get some more cleaning materials!).

    We have a full maintenance schedule and log, which includes visual checks for the power leads etc...

    Here we used a small air compressor (handheld) but at one of my primaries they have an anti-static vacuum cleaner which you can wear as a backpack. It's awesome

    Maybe, @elsiegee40 but it's a solution I also carry around in my mobile-toolbox too

    Out of interest what are you using? Been looking for a small portable air compressor to clean dust etc out of machines but only come up with the Hurricaine (£100 ish and iffy reviews) and the Datavac Electric Duster (which Im not sure has the grunt).

    We were advised not to use compressed air as it can push dust further into the projector rather than blowing it all out.
    We use a handheld dyson here, not cheap i know, but it lasts a good 15 minutes on a charge and recharges in 4 hours so i can get round our 180+ projectors in a couple of days.

    I did our projectors with a paintbrush. Took out the filters, brushed and then gave a tap on the desk!

    I did recently take apart a Toshiba (as part of the unifi 45) which has no filter and that was caked in dust. Compressed air was the only way forward.

    SmartBoart projectors supply on request a cleaning kit for theirs - it's a little bellows thing that slots in - I'd have thought compressed air was more effective but their kit is their recommendation.

    School vacuum cleaner (Henry) for cleaning in-situ, Giottos Rocket for blowing out internals eg pc cases. Using lung power isn't all that good for you and the Rocket (designed for cleaning cameras) never runs out of air, unlike cans.

    I've always used compressed air to clean projectors but I keep reading that all that does is blow dust back into the projector. It's just a case of finding a suitable vacuum for a reasonable price.

    It's the Datavac


    Oh it has grunt. It could blow the wig off a bald man from 100 feet. It's noisy and VERY effective. It certainly blows a LOT harder than any of the cans of compressed air.

    That Datavac looks the bees knees!
