This is a vacuum unit dedicated to one function—collecting trace evidence at the crime scene. Venturi-controlled suction for surface vacuuming and hermetically sealed, single use filter assembly eliminate cross contamination from individual crime scenes. The entire sealed filter assembly in its evidence bag is submitted to the crime laboratory for examination. The 619E is equipped with a manually controlled venturi to restrict suction to top surface vacuuming only when required.

7 ft. Extension Hose included.
