Abstract: Apparatus and method for reducing airborne proppant adjacent a fracking material handling system. In some embodiments, a proppant storage chamber is configured to store a volume of proppant. A blow-in adapter mates with a first port of the chamber to facilitate a flow of proppant into the chamber at an inlet pressure. A filter assembly covers and filter a first aperture of the chamber to reduce an emission of airborne proppant during the transfer of the proppant into the proppant storage chamber. A vacuum adapter mates with a second port of the chamber to supply a negative pressure to the chamber during the filling process to maintain an internal pressure within the chamber below a predetermined pressure threshold.

Abstract: Apparatus for reducing airborne proppant adjacent a fracking material handling system. In some embodiments, a proppant reduction cover is mounted over a first aperture of a proppant storage chamber and has a permeable filter material adapted to facilitate a first flow of displaced air therethrough as proppant is loaded into the chamber. A vent sock is mounted over a second aperture of the chamber and has a permeable filter material facilitate a second flow of displaced air therethrough during the loading of the proppant. A vacuum adapter is mounted over a third aperture of the chamber to apply a negative pressure to an interior of the proppant storage chamber during said loading of the proppant.
