Ward Filter Systems has been manufacturing and installing our NO SMOKE direct source capture, apparatus-mounted automatic diesel exhaust removal systems since 1987. Our products meet and exceed standards set forth by OSHA, NIOSH and NFPA. The original NO SMOKE system was originally designed in the 1980’s and is the system needed for vehicles with engines built prior to 2007. NO SMOKE 2 was developed to meet exhaust removal needs for vehicles with engines built with 2007 and newer EPA emission compliant components. We are committed to the health, safety, and well-being of the men and women in the fire service, specializing in the mitigation of harmful diesel exhaust effects. Our No Smoke filter systems are apparatus mounted, allowing for portability and indoor protection, greater flexibility for movement of apparatus within the station, and on-scene protection. The No Smoke filtration technology provides the best and only vehicle mounted exhaust protection available.
