A pouch is provided for the blower unit of a powered air-purifying respirator system, to isolate the blower unit from hazardous material such as potentially-explosive dust or gas. The pouch has an opening at one end through which the blower unit can be inserted into the pouch, and is shaped at the other end to receive the blower unit. It also has air inlet openings positioned to register with air inlets of the blower and permit the connection of the filter cartridges thereto, and an air outlet opening positioned to register with the air outlet of the blower unit and permit the connection thereto of a breathing tube of the respirator system. When the blower unit is inside the pouch, seals at the pouch openings inhibit or prevent particulate or gaseous material from entering the pouch through the openings.
