We review the Rupe S145EPL vacuum dust extraction system. This electro-pneumatic vacuum is double-filtered to ensure clean air is filling your shop space. The Rupe dust extractor is an electric vacuum that can be triggered "ON" by a pneumatic or air tool. Once you push the throttle on the sander, it automatically calls on the vacuum, removing the sanding dust.
A fleece bag first filters the air and catches all the large particulate. The secondary pleated cartridge filter removes that smaller debris and ensures that the air exiting the unit is clean and dust-free.
You can get the Rupes S145EPL for about $600, depending upon which kit you buy.
