For years I was blowing off dust with an air gun, just a quick blast after each sheet and hated it. There was not a huge amount per sheet, but besides getting it airborne and having to breathe the dust, it would accumulate behind the machine getting mucked up in the wiring, on the lead screws and on the linear bearings. Mine is a water cooled spindle, but the electronics cabinet suffered all the same.
I finally got a pair of Airpro collets for 2 of my HSK63F holders. I run them on my main tool, a 3/8 2 flute compression, and a 3/8 mortise compression I use for dados and 1/2 inch material. For me, If I use a single pass it still leaves a VERY small amount of dust, but since I onion skin all through cuts anyway, there is ZERO dust left on my table. I am about 2 years into this system and I love it. This is quicker than a sweeper pass and leaves me with better part holding. After accounting for drilling, dados and onion skinning small parts, adding the second pass to large parts as well does not cost me an awful lot of time. My average sheet cycle is 11 minutes. I could get that down to 8 or so without the second pass, but it is well worth it to me, and the machine only runs 20 to 24 hours on an average week.
I do also occasionally run my 4 inch spoilboard cutter surfacing program at .5mm in air after I have been carving or doing solid wood. This takes around 75 seconds. Some of of the wood shavings get pushed aside by the brushes and get left on the shoulders of the grid table but the spoilboard itself is pretty clean.
