The 2.5 and 3” line vacuum conveyors convert hose, tube or pipe into an inline conveying system for materials up to 900°F (482°C). The air-operated conveyors are available with smooth ends to fit into hose or tube and be secured with a hose clamp. Alternately, they are available with NPT threaded ends to mount onto threaded pipe. Large throat diameters help maximize throughput capability. The conveyors eject a small amount of compressed air to produce a vacuum on one end, resulting in high output flows on the other. The response is instantaneous. Regulating the compressed air pressure provides infinite control of the conveying rate. Construction is Type 303 or Type 316 stainless steel to resist temperature, corrosion and contamination. Applications include sampling hot flue gases, exhausting fumes and conveying soot, ashes, salts and other hot debris.
