Abstract: An air compressor system having a cast separator tank for use with an oil-flooded air compressor. The cast separator tank including an integrally cast air-end inlet opening which is mountable in face-to-face engagement with an air-end discharge opening of the compressor; an integrally cast first channel which extends between the air-end inlet opening and a separation chamber; an integrally cast second channel which communicates with a lower portion of the separation chamber and which extends along an outer portion of the cast separator tank; and an integrally cast lip which extends around an inner wall of the separation chamber. The integrally cast air-end inlet opening which is mounted to the discharge opening of the compressor, serves as a mounting foot, and supports the compressor on its discharge end. The compressor system further having a motor, such that the compressor, the motor and the cast separator tank are attached to from a single unit for ease of handling.

Abstract: A gas compressor refrigeration system including a chiller for cooling gas, a separator for separating condensate from the gas, and a reheater for heating the gas. The system also includes a closed refrigerant system which passes a charge of refrigerant in series, through a compression unit, then through the reheater in which the refrigerant exchanges heat with the gas, then through a condenser in which the refrigerant exchanges heat with ambient air, and then through the chiller.

Abstract: An air compressor system having a cast separator tank for use with an oil-flooded air compressor. The cast separator tank including an integrally cast airend inlet opening which is mountable in face-to-face engagement with an airend discharge opening of the compressor; an integrally cast first channel which extends between the airend inlet opening and a separation chamber; an integrally cast second channel which communicates with a lower portion of the separation chamber and which extends along an outer portion of the cast separator tank; and an integrally cast lip which extends around an inner wall of the separation chamber. The compressor system further having a motor, such that the compressor, the motor and the cast separator tank are attached to form a single unit for ease of handling. The compressor system also has a plurality of mounting feet for attachment to an appropriate subbase.

Abstract: An aftercooler through which a first fluid passes. A cooling fan applies a cooling fluid to the aftercooler. A variable speed motor is rotatably coupled to the cooling fan. A temperature sensor, in communication with the first fluid, is located downstream of the aftercooler. A controller controls operation of the variable speed motor based upon the temperature applied to the temperature sensor to prevent condensate freeze-up.
