Abstract: A tee coupling for coupling a handheld vacuum line to a main vacuum line of a commercial vacuum system without the need for external adapters includes a cylindrical main body portion with an axis, an inner diameter smaller than the outer diameter of the main vacuum line segments, a downstream end and an upstream end extending in opposite directions from the main body portion along the same axis, the downstream end and the upstream end each having an inner diameter at least as large as the outer diameter of a main vacuum line segment. a third end extending from the main body portion at an angle that is typically not a right angle from the axis; and a throat between the third end and the main body portion. The throat meets the main body portion at an angle that is not 90 degrees and is biased toward the downstream end.

Abstract: A vehicle vacuuming system that includes: a vacuum housing having an air filter, a motor within the interior volume of the vacuum housing wherein the motor supplies air suction power to a vacuum air intake distal from the motor and through a vacuum hose operably engaged with the vacuum housing, and an air outlet proximate the motor; and a pressure notification system chosen from the group consisting of a light, a speaker, a mobile application, and combinations thereof operably connected to a pressure sensing system associated with the vehicle vacuuming system.

Abstract: A one-hand engageable vacuum tool connection assembly for connection to a commercial vehicle vacuum system that includes: a vacuum tool connection assembly hose having a first end and a second end; an upper assembly and a lower assembly having a tool connector where the tool connector engages a second end of the lower assembly swivel cuff and is typically adapted to receive one or a plurality of different types of vacuum tools. The vacuum tool engagement assembly is typically free of any flapper valve, metal or spring biased elements.

Abstract: An air pressure-based flow meter assembly for a vacuum hose of a vehicle vacuuming system capable of measuring static pressure and dynamic pressure that includes a cover having an upstream end with an upstream cover opening and a downstream end with a downstream cover opening, a venturi insert disposed within and coupled to the cover, and a flow meter engaged with the cover and attached to the venturi portion of the venturi insert such that the flow meter is in airflow contact with the venturi portion.

Abstract: A vacuum motor assembly that includes a motor comprising a drive shaft; an impeller having a plurality of impeller blades spaced radially around a center portion of the impeller. An impeller cover that forms an air channel is spaced around the impeller and the impeller cover includes a front portion; a back portion engaged to the front portion; and a back support. The drive shaft of the motor passes through the drive shaft receiving hole of the back support and engages with the impeller. A front surface of the impeller defines a vertical plane and a first air channel interior distance from the front portion inner surface to the vertical plane within the airflow channel is greater than a second air channel interior distance measured from a back portion inner surface to the same vertical plane.

Abstract: The present disclosure includes a vacuum stall canopy assembly for a car wash system having a first post assembly having a base leg permanently attached to the ground, a beam attached to the top of the first post assembly, a roof assembly disposed on an upper portion of the beam, a debris separator disposed on the beam, the debris separator having a first side and a second side, a main airline fluidly connected to the debris separator and configured to be connected to a source of vacuum suction, a first hose on the first side of the debris separator, and having a first nozzle on a distal end of the hose from the debris separator, and a second hose on the second side of the debris separator, and having a second nozzle on a distal end of the hose from the debris separator.

Abstract: A vacuum cyclonic separator that includes: a main body having a top surface with an air outlet, a bottom perimeter defining a bottom aperture of the main body, at least two downwardly facing air inlets and at least one side wall extending between the top surface and the bottom portion and shaped such that air received within an interior cavity of main body moves in a cyclone and wherein the at least two downwardly facing air inlets are in at least substantially the same plane as the bottom perimeter of the main body; and a dump valve assembly capable of being opened and closed with one hand where the dump valve is engaged with the bottom portion to seal the bottom aperture of the main body.
