Abstract: Systems and methods for a compressor system are provided for selectively operating the compressor system with reduced power consumption. An output demand level of the compressor system can be monitored over time to identify a demand profile. A pressure setpoint for the compressor system can be selectively adjusted based on the demand profile, including to selectively transition between an operational pressure setpoint for an active demand profile and a reduced pressure setpoint for an inactive demand profile.

Abstract: A coupling device can be disposed between a power source and a compressor to selectively couple the power source to the compressor. A control device can be configured to selectively move the coupling device between a disengaged configuration, wherein the power source is decoupled from the compressor, and an engaged configuration, wherein the power source is coupled to the compressor via the coupling device.

Abstract: A measuring instrument for use with a gas compression system includes a housing having a face, a rear panel, and a wall extending between the rear panel and the face to define an instrument space. A curved tube includes a first end connected to a source of pressure. The curved tube is disposed within the instrument space. An indicator needle is coupled to a second end of the curved tube and is movable with respect to the face in response to changes in pressure from the pressure source. The needle and the face cooperate to indicate a measured pressure of the source of pressure. An electronic display is disposed within the instrument space and is visible through an aperture formed in the face. The electronic display is operable to display data unrelated to the pressure of the source of pressure.

Abstract: A portable light tower including a frame, and an enclosure supported by the frame. The enclosure defines an enclosure interior having a hot zone, and includes a plurality of inlet apertures and a plurality of discharge apertures. A generator driven by an engine are located in the enclosure interior and the generator and engine emit a hot exhaust gas into the hot zone during operation. The light tower also includes an exhaust chamber located in said hot zone, said exhaust chamber having a floor panel and a fan mounted in said floor panel for drawing the hot gas into the chamber and out the discharge apertures. The chamber is adapted to prevent the backflow of hot gas into the enclosure interior. The tower also includes a unitary forklift and bail plate and at least two retention assemblies located along the exterior of the enclosure for maintaining an enclosure door in open and closed positions.
