The Sirchie 48" Advanced Forensic Workstation is designed for those laboratories that won't want to change filters between applications. With a dual filter bed, the AC6400A is ideal for departments who process a large volume of evidence with powder and chemicals. Simply stack a HEPA filter, with an electrostatically charged pre-filter attached, in the bottom of the unit and place a bonded chemically absorbent carbon filter on top to complete the basic forensic application configuration. The AC6400A has a large vertical workspace to accommodate a microscope or a fuming stand. The unit is available in a manual dual-speed configuration as well as with the AirSafe Automatic Controller.
