|Dust collectors do a good job of keeping the dust and chips off the floor and out of
the air, and saving broom handle time. But when it's time to empty the bag the good
times are over. Dust gets all over and fills the air, usually along with much
cursing. Installing a cyclone ahead of the dust collector is an easy way to add
value to your dust collection system. The cyclone will catch a very large percentage
of the dust before it gets to the bag, and will also keep any larger pieces from passing
through the dust collector impellor which might do damage. A commonly available
accessory is a plastic cyclone lid which is placed on a 30 gallon trash can. These
do work, but the 30 gallon size is small and you still must dump the dust into a different
container for curbside pickup.
is a step up from the plastic version. I have it mounted to the wall above a green
waste container. As the cyclone separates the dust from the air stream, the dust
falls out the bottom and collects in the green bin. When the green bin is near full,
I can remove the flex hose connection and remove the lid, then roll the bin out to the
curb for pickup. I have a window in the lid so I can monitor the dust level in the
bin. Allowing the bin to fill and backup into the cyclone would be a real mess.
In our area the city allows sawdust to be placed in the green waste containers.
This is wise on their part because dry sawdust is a great counterpart to lawn clippings in
the composting process. Not all communities allow this so we are fortunate.
