- Include parts required to build a full system or to replace worn parts on existing PAPR (powered air-purifying respirator) systems
- PAPRs have a belt-mounted blower unit that passes ambient air through a filter before sending it to the headgear so workers have clean, breathable air
- They allow workers to move freely and unrestricted because the filter and power source are worn on the body
- System parts are compatible with components of the same brand and series
