Industrial suppression panels, surplus from job site $45 each ($200 for all six)

Six Dellmark suppression panels, 4x4 feet each. Steel frame, polymer mesh interior, rated for ambient anomalies up to a 7 on the Greylin scale. These are the contractor-grade ones, not the residential ones that barely suppress a 4.

Got them off a demolition job in the Shovnik industrial corridor. Building was coming down anyway and the foreman said take whatever. Panels are in good shape. Some paint overspray on two of them but it doesn't affect performance. I tested them in my workshop on a persistent draft that I'm pretty sure isn't wind and they handled it no problem.

Good for workshops, sheds, basements, anywhere you've got low-level activity you don't want to deal with. Not rated for anything above a 7, if you've got a 7+ situation you need professional containment and honestly you should probably already know that.

$45 each or $200 for all six. Can deliver within Shovnik for $20.
