Abstract
An air vacuum system is provided. The air vacuum system is used to clean or remove dust particles or other particulate matter from a building. The vacuum system includes an air vacuum outlet flush-mounted with a floor region of the building. The air vacuum outlet comprises a vacuum port operably coupled to a vacuum supply. Further included with the air vacuum outlet is a vacuum port cap which can be mounted within the vacuum port to seal the air flow within the vacuum supply. The vacuum port cap is designed having a pivot arm which extends from a position flush with the surface of the cap to a position in which a user can grasp the arm and lift the cap from the port. The arm thereby pivots about an axis which extends through a receptacle formed within the upper surface of the cap. The receptacle is used to receive the pressed end of the arm for allowing the opposed end to protrude upward. The opposed end includes flanges which can be grasped by the user's fingers to remove the cap from the vacuum port.
