The Smart Pro™ Dust Collector from Oneida Air Systems has patent-pending Smart Air Control Technology™, which automatically adjusts to maximize dust collection at each tool. It maximizes air volume for large tools like planers and table saws and increases the suction for CNC routers, panel saws and hand tools. The 35-gallon metal drum under the cyclone comes with Oneida’s Dust Sentry™ sensor that indicates when the drum is full, and the filter includes the patent-pending Flame Guard Arrestor™. The Smart Pro Dust Collector comes in 2hp and 3hp versions, with prices starting at $1,987.
