Hello all! I am setting up my shop and was curious if anyone had any suggestions on dust collection in a sanding room? I have worked in factories and don’t want to buy a full torrent collection system. Looking for a solution that can handle a good amount of boards, but is less maintenance and pulls less power. If you have any ideas or suggestions let me know!
Thanks!
Reduce size of working place, where venltilated, to just what you need. In this place push air from the top throug wide F7 filter and suck at floor with wide surface cleanable G4 filter. Everywhere of this working place you want 0,2 to 0,4 m/s wind speed, not to much so you only help dust fall to collection.
Lemat is right. Circulation. Air pulled in on one end and pushed out at the other. Ventilation up high near the ceiling is good for respiration, but I also like to have a fan pulling air in at the floor. Pulling air in at the floor(12”or 18” above floor level) catches dust before it hits the floor and is pushed and pulled out of the room at the other end. Ventilation at the ceiling doesn’t need a fan, just a vent. Dust collection shrouds on your sanders are good but sometimes more hassle than they are worth. If you are doing any production, they restrict your movement too much and slow things down. If that doesn’t matter and you can get a shroud that will fit an eight inch pad, a vac and a cyclone will get rid of most of your dust
Ideal is full ceiling air push with filter and fan and “full” floor outake with filter and fan choose to keep room in depression.
It’s a standard industrial system when you have to work with solid particules, low pressure ceiling push with high pressure powder sucker floor.
Plus need to suck high speed particules directly at sander so need to mostly use real roto orbital with vacuum sander for main sanding job, only use rotative sander polisher for small quick material remove, laps prep, open boxes.
A good shroud for an eight inch pad like Flex Pad or Ferro Pads is hard to find. Lots of companies make cheapo clear plastic shrouds like the ones I used to see at Home Depot and Loews. Problem usually is that they are 7” diameter . Makita makes one specifically for their sander/polisher. It accommodates a seven to nine inch pad. The kicker is that it is about $100. Very good quality though and worth the $$$. CPO Tool Outlet has the Makita Sander/Polisher factory reconditioned for $149. Savings of at least $100. They also sell the shroud. I think though that the sander/polisher is currently only sold through EBay. CPO Factory Reconditioned tools are tools that were returned to Makita because they had some issue from the factory. Usually some defect like wiring, faulty switch etc. I would rather have a factory reconditioned because that means it has been returned to the factory, the issue repaired and the tool has been throughly inspected.
