My shopvac has an Oneida Dust Deputy cyclone in front of it and a HEPA filter inside. Last weekend I was vacuuming shavings from hand planing and overfilled the bucket. The result was shavings and other debris was vacuumed into the vacuum’s bucket and made a mess of the filter. Prior to that, the filter stayed nearly pristine indicating everything was being caught by the Dust Deputy cyclone.
This has to be more gruesome if it happens to a dust collector with a cyclone. To counter it the dust collector makers sell bin full sensors, but they aren’t cheap and depending on the cyclone maker, use different technology.
Penn State has a rotating paddle that cost $80 and sounds a horn.
Oneida has a rotating paddle that flashes a strobe for $260 and an infra red optical sensor that flashes a strobe for $150.
Clearvue has an optical sensor that flashes a strobe and sounds a horn for $225.
I couildn’t find a sensor in the Grizzly catalog.
It would appear that most of the sensors could be used on any brand’s cyclone bin.
Do you have a sensor on your bin? Does it work ok? If you don’t have a sensor, have you ever overfilled the bin?
Note: while non-cyclone dust collectors often have transparent collection bags, the cyclones use metal or cardboard drums that are opaque.
