ABSTRACT:
An air filtering module for supplying air comprising a module housing having a rear plenum portion and a front frame portion united together. The plenum portion has a rear air inlet opening. The frame portion has a planar front air outlet opening and has a continuous outer perimeter wall extending substantially perpendicular to the plane of the air outlet opening. A replaceable air filter cartridge and a fan assembly are mounted in the module housing. A perimeter barrier gasket is permanently united to the outer perimeter wall. A plurality of perimeter connecting structures permit mechanical fastening of the outer perimeter walls of adjacent module housings together in an array of modules in a manner compressing the barrier gasket to block air flow between the module housings. The module housings are easily separated from a fastened condition without damage to the perimeter barrier gasket for reconfiguration of an assembly of module housings reusing the barrier gasket. Also, support legs and a shield system and a curtain system are connectable to the module housing.
