The Exair 2.5" and 3" High Temperature Line Vac Conveyors are designed to convert hose, tube, or pipe into a powerful in-line conveying system for high temperature materials up to 900 degrees F. These air operated conveyors are available with smooth ends, to fit into hose or tube and secured with a simple hose clamp and they are available with NPT threaded ends, to mount onto threaded pipe. The conveyors eject a small amount of compressed air to produce a vacuum on one end, resulting in high output flows on the other. Regulating the compressed air pressure provides infinite control of the conveying rate. High Temperature Line Vacs are CE compliant and available in seven sizes from 3/4" to 3".
