When source capture is not practical due to the size of an area, or poor access to points of generation, we recommend using an “area” or “ambient” air cleaning system. This system is specially equipped to handle heavy chemical vapors. It operates by collecting the vapors into a multi-stage filter package which includes a double pass activated carbon system. The clean air is then exhausted back into your workspace through a directional grill. Single units or multiple units are suspended in a workspace to achieve a continuous air pattern and filter the air 6 to 8 times per hour.
