Vacuum Generator
Vacuum Generator
The Venturi/Vacuum Generator is designed for corrosive or high purity gas applications. The design consists of two machined high purity PTFE body halves attached using a tongue and groove sealing mechanism. The concept of a venturi valve is a short tube with a tapered constriction in the middle that causes an increase in the velocity of flow of a fluid and a corresponding decrease in fluid pressure. This is used in measuring flow or for creating a suction. The lack of moving parts eliminates the possibility of media contamination.
Materials of Construction:
- Wetted Surfaces – PTFE
- Non Wetted Surfaces - PVDF, 18-8 stainless steel
- 0 to 120 PSIG (8.3 bar)
- Pressure ranges above are for operation at ambient temperature.
- 0° - 150° F (-17° - 66° C) Ambient
- 0° - 266° F (-17° - 130° C) Fluid
- Clean Dry Air, N2 or any other available gas
- At 40 PSIG: 1.60 SCFM
- At 60 PSIG: 1.75 SCFM
- At 80 PSIG: 1.80 SCFM
- Integral nozzle on inlet body half eliminates the need for calibration and realignment.
- PTFE wetted surfaces eliminates contamination and fluid compatibility issues.
