Gast VG-020-00-00 Venturi Vacuum Generator 4 Cfm

Product Description

The GAST VG-020-00-00 is a single-stage venturi vacuum generator designed for industrial and light commercial pneumatic applications. It produces up to 4 CFM open flow and achieves a maximum vacuum of 27 inches of mercury (in/Hg) without any moving parts, using compressed air flow through an internal venturi to create suction. Operating on a 3/8 FPT vacuum port connection, it consumes 6.4 CFM of supply air at a maximum inlet pressure of 30.75 psi. The compact body measures 8.18 inches in length, 1.66 inches wide, and 1.66 inches high, making it suitable for space-constrained installations. Licensed trades and maintenance technicians install these units as part of automated pickup, clamping, or process vacuum systems.

The VG-020-00-00 is suited for applications requiring a reliable, low-maintenance vacuum source in automation, material handling, and process control environments. Because there are no rotating or reciprocating components, it is a practical choice for clean-room-adjacent setups or locations where motor noise and vibration are a concern. Typical installations include vacuum chucking, pick-and-place assemblies, and pneumatic conveying assist systems in both light industrial and commercial settings.

Key Features

• Maximum vacuum of 27 in/Hg with no moving parts
• 3/8 FPT vacuum port for standard pneumatic plumbing
• Maximum operating pressure of 30.75 psi
• Air consumption of 6.4 CFM at rated conditions
• Compact form factor: 8.18 x 1.66 x 1.66 inches

Compatibility

Designed as a direct-fit venturi vacuum generator for pneumatic systems requiring a 3/8 FPT vacuum port connection and compressed air supply at or below 30.75 psi inlet pressure.

Installation Notes

Installation is performed by qualified pneumatic or mechanical technicians. Depressurize and lock out the compressed air supply before connecting or disconnecting the unit. Use thread sealant rated for compressed air on all FPT fittings and verify connections are leak-free before returning the system to service. Do not exceed the rated maximum inlet pressure of 30.75 psi, as overpressure can reduce vacuum performance and risk fitting failure.
