The CAVN-20 Retractable Nozzle Vacuum Sealer combines the convenience of a built-in compressor with inert gas flush capability. This self-contained design eliminates the need for an external air source, while the gas flush feature protects oxygen- and moisture-sensitive products. With a 20” seal length and 1/4” seal width, the CAVN-20 is ideal for food packaging, supplements, pharmaceuticals, electronics, and cleanroom applications.
