UNIJET venturi vacuum generators effectively use compressed air to generate vacuum. Unlike traditional vacuum pumps, UNIJET.venturis are compact with no moving parts. Venturis require no maintenance, do not generate heat and are capable of generating vacuum levels as high as 26" of Hg.
These venturi devices create .8 to 2 CFM of vacuum flow and produce 26" of Hg of pressure using only 80 PSI of compressed air. Since there are no moving parts, this is a great vacuum source - reliable, efficient and surprisingly quiet.
Compressed air flows through a small circular opening to generate a high velocity. This air expands, resulting in decreased pressure to provide vacuum levels
