The LDV 2000 Vacuum Concept Conveying System is a dilute phase, high velocity, low pressure, continuous vacuum conveying system for shorter distances. It is generally used to convey low to medium density and non-abrasive materials. Examples include flour, kaolin clay, plastic pellets, grain, malt, corn, starch and plastic resin.

Typical conveying velocities are generally in excess of 4000 feet per minute (20 m/sec) and vacuum conveying pressures of up to 15 inches (381 mm) of mercury (hg).

The material is fed into the conveying line on a continuous basis by vacuum which is supplied by a low pressure positive displacement blower. The system includes a vacuum pickup nozzle, vacuum conveying line, a vacuum filter receiver, a rotary airlock feeder and a positive displacement blower.
