Abstract: A rotary-screw air compressor having a separator, a cooler fan assembly, and a mounting apparatus. The separator has a first chamber and a second chamber. The first chamber separates compressed air and coolant. The second chamber separates compressed air and moisture. The separator is disposed in a chasm formed by a first platform. The mounting apparatus elevates a motor and air end vertically above and spatially apart from the separator. A cooler fan assembly is vertically above the motor and air end. The cooler fan assembly has a first heat exchanger vertically above a second heat exchanger. A shroud having an opposite open end is connected to the first heat exchanger at one open end and the shroud is connected to the second heat exchanger at the other open end. A cooler fan is disposed completely within the shroud and between the first and second heat exchangers.

Abstract: There is a cooler fan assembly having a shroud, a fan blade and motor to produce an air flow, a first heat exchanger, and a second heat exchanger. The first heat exchanger cools compressed air; the second heat exchanger cools a coolant. The shroud defines an air passageway. The air passageway directs an air flow produced by the fan blade and motor in a path having a direction going into an inlet portal of the shroud and out of a discharge portal of the shroud. The first heat exchanger is coupled to the shroud and is in the path of the air flow. The second heat exchanger is coupled to the shroud and is in the path of the air flow. The fan blade and motor is completely disposed within the shroud.

Abstract: A cooler fan assembly having a shroud, a means to produce an air flow, a first heat exchanger, and a second heat exchanger. The shroud defines an air passageway. The air passageway directs an air flow produced by the air flow means in a path having a direction going into an inlet portal of the shroud and out of a discharge portal of the shroud. The first heat exchanger is coupled to the shroud and is in the path of the air flow. The second heat exchanger is coupled to the shroud and is in the path of the air flow. The means to produce an air flow is completely disposed within the shroud.

Abstract: A cooler fan orifice assembly and a cooler fan orifice ring for adjusting the tension of a fan belt of a compressor. The assembly includes a motor mount section having a generally rectangular frame and having an adjustable mechanism that is connected to the fan orifice ring and the compressor motor, the adjustable mechanism causing the motor and the fan orifice ring to slideably move together so that the tension of the fan belt can be changed without dissembling the motor, orifice ring and guard.
