  • Patent number: 9541332
    Abstract: A heat exchanger for use in cooling a flow of compressed gas with a flow of cooling fluid includes a body portion having a first end, a second end, and a space between the first end and the second end. A tube bundle includes a first tube sheet, a second tube sheet, and a plurality of tubes extending between the first tube sheet and the second tube sheet. The tube bundle is insertable into the space from either the first end or the second end. A first head includes an inlet and an outlet, the first head connected to the first end and connectable to the second end and a second head is connected to the second end and connectable to the first end such that cooling fluid enters the inlet, passes through a portion of the plurality of tubes, contacts the second head and flows through a second portion of the plurality of tubes to the outlet.

  • Patent number: 9261104
    Abstract: A fluid compression system includes a compressor, an electric motor including a stator and a rotor positioned adjacent to the stator, and a shaft coupled to the rotor to support the rotor for rotation and having a drive end and a non-drive end. A plurality of flow-inducing elements are integrally-formed as part of the shaft and is adapted to induce a flow of fluid from the non-drive end toward the drive end in response to rotation of the shaft.

  • Patent number: 9121416
    Abstract: A fluid compression system includes a compressor unit that directs a flow of compressed fluid to a first heat exchanger. A second heat exchanger receives a flow of coolant. A blower produces a flow of ambient air that passes through the first heat exchanger and the second heat exchanger so as to direct cooling air through both heat exchangers. A variable speed motor is coupled to the motor in addition to a control system to vary the motor speed between a low speed and a high speed.

  • Patent number: 7972401
    Abstract: An air intake filter assembly for filtering air flowing from a front end to a rear end includes a housing, a first filter stage, and a second filter stage. The filter stages are insertable in and removable from the housing. A latch is movable between a latched position in which the first filter stage is secured to the housing, and an unlatched position in which the first filter stage is not secured to the housing. A hinge is formable between the housing and the first filter stage, and the hinge allows the first filter stage to pivot with respect to the housing when the latch is in the unlatched position. When the first filter stage and the second filter stage are inserted in the housing and the latch is in the latched position, then the first filter stage is compressed against the second filter stage, which is compressed against the housing.
