Various supports and engagement members allow for horizontal and/or vertical engagement of a plurality of the air movers for storage or increased air moving capacity for a given application. An alignment guide assists with positioning of the air mover with respect to a room wall to enhance air flow within the room. A cord retaining system provides an enhanced approach for securing the air mover's electrical cord. Grill guards have slotted ends to assist with assembly of the air mover.Type: ApplicationFiled: October 27, 2015Publication date: February 18, 2016Inventor: Grant L. Reuter

Publication number: 20160047396Abstract: A vacuum generator which operates on the ejector principle. A multi-stage ejector has a plurality of nozzles arranged in a row. An air stream, an air from a compressed air connection flows through these nozzles at high speed to an outlet so that a negative pressure is generated in a valve chamber which surrounds the nozzles. A shut off valve closes the air outlet in an air tight fashion. The valve chamber or an evacuation chamber in which the negative pressure is generated has a conduit which is closed by an aeration valve which cooperates with the shut off valve, by which an aeration conduit for aerated the chambers in which the negative pressure is generatable is opened.Type: ApplicationFiled: June 10, 2015Publication date: February 18, 2016Inventor: Alfred Bilsing
