Walk-In Clean Air Stations
Self Contained Air Filtration Equipment Using Patented DualDraw ® Airflow Technology
DualDraw Walk-In Clean Air Stations are designed to address the most challenging indoor air quality problems. Operators that work on large or awkward parts oftentimes cannot easily place them under a fume arm or on top of downdraft table. Therefore, breathing zones are left unprotected and operator health is compromised. Additionally, cross contamination of plant equipment by airborne dust is left unchecked. Walk-In Clean Air Stations address these challenges – they are self contained filtration rooms that enclose applications generating harmful dust, smoke, or fumes.
Our Self-Contained Air Filtration Equipment is sized based on the application in question and are equipped with a unique slotted adjustable tube regain air system. Each Walk-In Clean Air Station incorporates the patented DualDraw airflow design combined with a filter system specifically designed to handle the particular hazard.
The DualDraw approach to downdraft quality and performance is unique in the marketplace – we guarantee your satisfaction.
