Recirculation of Industrial Exhaust Air Pilot Study (Field Evaluation of Air Cleaners and Monitors) at Rexnord Inc., Environmental Research Center, Milwaukee, Wisconsin.
NIOSH 1980 May:148 pages
Performance characteristics, maintenance requirements and reliability of pilot scale air cleaners and monitors were evaluated. A set of evaluation criteria was developed for recirculation components. System components which included an aspirated cartridge filter, particulate air monitors, ozone monitors and a safety monitoring filter were tested on industrial welding exhauts to evaluate performance, potential failure, and requirements of proper maintenance. The authors conclude that the criteria can be applied to any recirculation system. They recommend that the technical and economic feasibility of recirculation be assessed by pilot testing procedures, and a mobile recirculation system incorporating pilot scale devices to conduct pilot scale testing be used.
