New position with 100+ VFD's all sizes in many different locations/environments all indoors, looking for a good ESD vacuum/blower rig for cleaning the dust out of them. Any additional tips on cleaning them greatly appreciated!
 
I'm not a fan of blowing, it tends to push stuff into places that were not supposed to be in the air stream.

I used to have one of these ESD safe vacuum systems (I no longer to maintenance work so I sold it). I saw a copier tech using one, he highly recommended it so we bought one for VFDs.

Great little unit, just make sure that you ONLY use their accessories with it. All the plastic parts must be made of the same material, otherwise you can get static buildup.
 
Thanks! I know about using any high pressure air or canned air, old school guy showed me years ago how to vacuum them while using a blow dryer (no heat of course) to just loosen things up, last thing you want is high pressure air because the dust/debris gets forced into nooks and crannies. Omega seems perfect especially with the 16 foot hose accessory...models i looked at all seemed to have hoses 6 foot or shorter, thanks again.
 
I retired from a large hospital/research center that had over 500 VFD'S from 2 to 1,750 HP. they purchased us 1/4 HP 120 volt air compressors for our tool carts to blow out drives that some were never cleaned in10 years. The first time that each drive was blown out we got cloud of dust. We PM'S drives from once to four times a year. I refused to use air compressor during hot humid summer due to moisture it blew out. They never purchased air dryer that I asked for. A vacuum cleaner would be lucky to pull out 10% of the dust especially on larger drives. We were lucky that over halve of the drives were located in a climate controlled room that never got above 80 degrees F. I asked techs from two different drive companies if they recommended blowing out energized drives like we did. Told us drive not only should be off but the 480 volt power to drive should be off.
