Abstract

Abstract A self-contained air monitoring unit with agitated air capability comprising a cabinet having an air pump compartment provided therein into which is furnished filtered air. A blower is provided in the cabinet for drawing air inwardly through the air intake of the cabinet through the air pump compartment and outwardly through a port at the rearward end of the cabinet. An elongated flexible hose may be secured to the air outlet on the cabinet to agitate the air within the space in which an asbestos abatement action has been conducted. A plurality of air pumps are located within the air pump compartment and have their intakes operatively connected to an air sampler located within the space in which the asbestos abatement action is being conducted. During the asbestos abatement action, the air pumps in the air compartment are contained in a clean environment and are cooled by air passing thereover.
