Abstract
The present invention is a dust abatement device that secures over a container. Powdery material, such as plaster, cement, grout or the like, is poured through the device, and mixed with water inside the container. The device has a mounting sleeve and radial manifold. The manifold forms a radial pneumatic channel with a circumferentially disbursed air intake that generates a radially uniform airflow to draw in airborne dust that would otherwise escape to the surrounding air. The manifold is connected to a vacuum with an air filter, and generates a dust shield zone above and around the device, which only extends down from the manifold a few inches. The manifold also funnels material and water into the container, and forms an inner eave that spaces material and water from the air intake, and forms a splash guard to retain upwardly projected splashes of material and water inside the container.
