  • Patent number: 6499965
    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.

  • Patent number: 6500243
    Abstract: An air compressor system having an air/oil separator for use with an air compressor, the air/oil separator including a separator tank having a side wall with an air exit port; a separator element hold down mechanism between the separator element and a lid mounted on the separator tank; and a separator element oil scavenge device which scavenges oil from the bottom of the separator element and passes the scavenged oil through the side wall of the separator tank. A method of replacing a separation element in a separation chamber of the air/oil separator including the steps of removing the separator element from the separation chamber without disconnecting the scavenge device attached thereto, and positioning a replacement separator element within the separation chamber, such that a scavenge device securely affixed thereto is caused to communicate with the side wall of the separator tank.

  • Publication number: 20020106287
    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.
