Abstract
A powered air purifying respirator system for use with at least one filter system includes: a housing including at least one inlet port and at least one outlet port; a motorized air flow system to draw air into the housing via the at least one inlet port; a control system in communicative connection with the motorized air flow system; and a filter system sensor in communicative connection with the control system. The filter system sensor provides information to the control system relating to the type of the at least one filter system upon fluid connection thereof with the housing. The control system can control the motorized air flow system at least in part on the basis of the type of filter system sensed by the filter system sensor. Another powered air purifying respirator system for use with at least one filter system includes: a housing including at least one inlet port and at least one outlet port; a motorized air flow system to draw air into the housing via the at least one inlet port; a control system in communicative connection with the motorized air flow system; and a pressure sensor in communicative connection with the control system to provide information to the control system relating to ambient pressure. The control system can, for example, control the motorized air flow system at least in part on the basis of the information relating to ambient pressure.
