Abstract
Electrical control and power supply systems are provided for powered air-purifying respirators (PAPRs). An exemplary electrical control system for a PAPR may be adapted to control the supply of power between a battery and a blower motor of a filtration unit of the PAPR. The electrical control system may include a plurality of integrated circuits that are capable of meeting minimum operating times while balancing power usage of various 'off-the-shelf' components of the filtration unit.
