PAPR (powered air purifying respirator) and SAR (supplied air respirator) air pumps, blowers and parts help to ensure optimal air system efficiency. Ambient air pumps are lightweight units that provide continuous flow to multiple workers. Complete blower units feature several filters that facilitate safe breathing. A broad range of replacement parts are also available for PAPR and SAR maintenance and repairs. Most replacement blower gasket and plug packages include five inlet and outlet units.
