Venturi loaders are the simplest of the loader types. They use compressed air through a venturi to generate the vacuum to suck material granules into the air stream which then conveys them to a small cyclone receiver.
The level of vacuum and amount of air flow makes these loaders suitable for short distances of 5 m or less. Given sufficient compressed air supply they can move a surprising amount of material but would be expensive (in terms of air) to run. Typically used for throughputs of less than 20 kg/hr.
