Rock Stoppers

Solution entered: 2/6/2008    Solution updated: 3/2/2008

Rock stoppers protect the vacuum filtration system by providing a collection point for heavy material before it collects in the vacuum HEPA filter. Rock stoppers can be shielded which also helps manage the dose that would have collected in the vacuum. The simplest rock stopper we have found is a drum/can with a lid, where the lid can have two holes cut into it and two pipe inserts (the ID of the vacuum hose) welded into the lid. They have similar units available on the market, but we have found it cheaper and quicker to have the site fabrication shop build them. Keep it simple. Some facilities with large volume of material to be collected use the same drum/can lid for numerous containers. Just move the lid from one can to the next. Have spare lids and rings staged to seal the used cans when full. Commercial rock stoppers are available from Power Products, NFS/RPS or Nilfisk.
