Abstract
The enclosure surrounds the shooter who fires his/her weapon from inside, adjacent the back wall, at a target and/or bullet trap located some distance away from the enclosure. Sole access to the enclosure, and the shooter's station therein, is through the open front end. Air circulation and filtration is supplemented by generating an air curtain across the open front end. Air venting and filtration of inside air is at a rate of 6 times per minute and provides a flow of clean air from back to front of the enclosure through a pressurized plenum in the back wall designed to create a uniform flow through the shooter's station. An auxiliary venting outlet in the top or ceiling of the enclosure provides a negative air pressure inside the enclosure so contaminated air escaping through the open front end is minimized.
