Abstract
The outlet of a blower extends through a hole in a circuit board to which the blower is attached. Electronics on the board control operation of the blower. The blower can be configured as two blowers in series, to provide more precise control of airflow. An air filter, such as an N95 filter is releasably attached to the blower intake on a front side of the circuit board. The front side of the board can be attached to a support panel, with a gap therebetween, and the air filter facing and in fluid communication with the gap. An air filter gasket is positioned around the edges of the front side of the circuit board, such that air sucked through the air filter over the intake of the blower, first passes through the air filter gasket between the circuit board and the support panel. The air filter gasket can be coarser than the air filter. The blower is well suited for use in a fuel cell apparatus, for supplying an electronically controlled airflow to the fuel cell.
