Simultaneously Reducing CO2 and Particulate Exposures via Fractional Recirculation of Vehicle Cabin Air7/1/2017 - Peer reviewed journal articlesAn article presenting research on fractional recirculation as a simple method to reduce exposures to particulate matter and CO2 in vehicles.
10/1/2014 - Peer reviewed journal articlesA report detailing ways to increase mine airflow to underground metal/nonmetal mine working areas to improve miners’ health and safety. One of those areas is controlled recirculation.
3/1/2014 - Peer reviewed journal articlesA report detailing the results of two controlled recirculation tests over three days at a Wyoming trona mine, utilizing an inline booster fan to improve airflow to a remote and difficult-to-ventilate development section.
1/1/1974 - Reports of InvestigationsThe Bureau of Mines has successfully used sulfur hexafluoride (SF6) as a tracer gas to measure mine air flows under conditions where conventional methods have failed. SF6 was employed experimentally to measure accurately recirculation of return into int...
