The VG-065-00-00 has a lightweight Delrin® construction that provides maximum chemical resistance, while also allowing for maximum flexibility and easy mounting. Built with no moving parts, these Gast vacuum generators require minimal maintenance and operate very quietly. In addition, their innovative Gast multi-venturi design uses less compressed air, yet delivers substantially more vacuum flow than single-venturi units making them the ideal choice for applications where a regular pump may not be preferred.
