VARIABLE FAN SPEED CONTROL
About CFM's: CFM (cubic feet per minute) is the way airflow is
measured. The Razaire 530 fan is rated at 530CFM, but you probably
won't want to run it that high most of the time. The fan will develop
up to 4 times as much vacuum or pull, as other portable dust collectors, so
at high settings it can pull very fine dust particles right through the
filter! To avoid this, turn the fan down or, if you need the extra
suction, add a second filter stage.

Razaire 530 Dust Collector
Pop has one of these and recommends it without any hesitation whatsoever.
Yes, it is a little costly (due to its quality components) ...but you will be amazed
at how great it works.
The Razaire 530 is the smallest, quietest, most powerful and versatile
portable dust collector in the world at only 11"x11"x4" and weighs 9.5lbs.
Because it is a modular system, it can
handle the dust control needs of any small home workshop - from collecting
dust at the source (rotary carving tools, belt sanders, etc) to overall
shop air filtration. How does it work? Basically, dusty air
enters the front of the unit, drawn in by a powerful impeller fan.
The dust is trapped by a filter that removes over 90% of 3-4 micron sized
particles (about the size of baby powder). Clean air is then
exhausted out the side.
For most carving applications, it is not
necessary to carve inside the acrylic hood -working 6" in front of it
usually provides satisfactory results. The 530 comes with a standard
2" filter which can easily be removed for cleaning.
