A motor-fan assembly includes a motor assembly having a tubular core with a rotatable shaft extending therethrough. The assembly includes a working fan assembly which has at least one working fan rotated by the rotatable shaft. A blower housing separates the motor assembly from the working fan assembly, wherein the rotatable shaft extends through the blower housing.

Motor-fan assembly with improved airflow and noise reduction properties

One or more techniques and/or systems are disclosed for increasing compressed air efficiency in a pump that utilizes an air efficiency device in order to optimize the amount of a compressed air in the pump. The air efficiency device may allow for controlling the operation of the air operated diaphragm pump by reducing the flow of compressed air supplied to the pump as the pump moves between first and second diaphragm positions. A sensor may be used to monitor velocity of the diaphragm assemblies. In turn, full position feedback is possible so that the pump self-adjusts to determine the optimum, or close to optimum, turndown point of the diaphragm assemblies. As such, air savings are achieved by minimizing the amount of required compressed air.

An air operated double diaphragm pump comprises an integrated electric generator and an air efficiency device. The integrated electric generator increases the portability of the air operated double diaphragm pump. The air efficiency device varies the amount of compressed fluid entering the pump between a high volume and a low volume dependent upon the velocity and position of the pump's diaphragm assemblies to optimize the pump's efficient use of the compressed air.
