The 21BVVB is Vent-Vac device that disperses leak detection powder or pre-coat. When the airflow is reversed, the Vent-Vac can act as a vacuum, cleaning out the dust from the dust collector. It serves as an outlet for the air valve, where the compressed air pressure travels through and moves the air out of the end of the outlet. This product is commonly used in facilities and is great for running leak tests.

Key benefits:
  • Vac comes with two clamps and one shut off valve
  • One piece vac can be unscrewed for cleaning
  • Requires some engineering to set up
  • Can be operated by most maintenance crew
  • Compressed air and hoses are required to operate
  • Easily converts from dispersion to vacumming
