Abstract
A portable compressor, which includes a compressor airend for compressing a fluid; a prime mover operably connected to the airend to drive the airend and thereby compress the fluid; and a portable compressor housing which defines a housing chamber having a chamber temperature. The compressor means and prime mover are located in the chamber. The housing has a first end and a second end and means formed thereon to provide for ambient air to flow through the first and second ends and into the housing chamber. The portable compressor also including a housing chamber temperature optimizing system comprising: fan for drawing ambient air through the housing ends. The fan is adapted for movement in a first direction to draw ambient air through the first housing end and in a second direction to draw ambient air through the second housing end. The system also includes a chamber temperature measuring member located in the housing chamber; and a motor for moving the fan. The motor is operably connected to the fan and is also in signal receiving relationship with the temperature measuring member. The motor is adapted to move the fan in a first direction to draw ambient air through the first housing end when the housing chamber temperature is above a set point temperature, and to move the fan in a second direction to draw ambient air through the second housing end when the housing chamber temperature is below a set point temperature.
