What's better than canned air?

Hi, Years beliefly had air cans. They made me feeling ill so I refused to use them afterwards. At former computer shop, they had pair of small vaccum cleaners (looks like oversized liquid laundry containers) that you can lug by it's handle but they were designed to vaccum or exhaust via hose. For it's size they were powerful enough to move heavy built up dust out. I think it was blue or green, made by Panasonic, it was long ago around 90-92 timeframe. At current TV shop work, we have heavy-duty air compressor and 1/2hp vacuum w/ flex 4" dia hose. Other tech used air to blow dust all over, I used both tools to blow off dust and trap dust with vac to cut down on dust floating around. Worked well. One thing, compressor is LOUD. Hissssss, clunk clunk chugg chug chug goes on for few minutes then with a clank, stop pumping up. That 1/2hp vac, is rather noisy too. More like roar actually. Both TVs & monitors attacts BIG heaps of dust by static action that is part of HV process. Cheers, Wizard
