Such securing means include at least two opposing adjustable fastening means, each of which includes an elongated strap attached to its lower end to an outer wall portion of the framework and extending outwardly a distance greater than the height of the filter cartridge. A bracket, having a slot which matches the strap so as to be slidable thereon, is mounted on the strap and adjustable means are mounted on the strap outwardly of the bracket and movable along the strap into forcing engagement with the bracket to urge the filter into engagement with the framework.

Abstract: An indoor gun firing range enclosure with a ventilation system for removing particulate matter, such as lead or other heavy metals, and unburned gunpowder, plus gaseous contaminants such as carbon monoxide, from the atmosphere within the enclosure to make the atmosphere within the enclosure safer for persons using the firing range.In addition, a method of ventilating the indoor firing range enclosure for the same purpose.Both the ventilation system and method of ventilating contemplate removing a portion of the air from within the enclosure and after removing particulate matter from this air, exhausting it to the out-of-doors. Concurrently, another portion of the air is removed from the interior of the enclosure for recirculation into the enclosure after particulate matter is removed from it. Out-of-doors air is also mixed with the recirculated portion of the air to make up for some of the air exhausted from the enclosure to the out-of-doors.
