Nex Flow™ Ring Vac™ air operated conveyors come in a variety of sizes and materials and configurations. Anodized aluminum versions from ½” to 3” standard size (and larger for special applications on request) are used to convey all sorts of material over large distances, both vertical and horizontal. 304 stainless and 316L stainless versions are used for food grade and pharmaceutical applications and for use in high temperature and corrosive environments. As these units do use a significant amount of compressed air, they are best applied where the air is available and in particular, intermittent use applications. Some applications only require low pressure to operate minimizing air use. The Ring Vac™ consists of a body, a generator (which creates the venturi effect) and a cap. The unit can be dismantled and easily cleaned if necessary.
