The Dilute Phase, typically defined as “at low pressure”, has a low efficiency ratio that usually is lower than 5 Kg of product per air Kg. The Dilute Phase Pneumatic Conveying can be performed through pressure or vacuum mode. Generally, it is used a blower to generate the force required to convey powder and granules.

This type of conveying system uses an airlock from a compressed air generator at a low pressure, usually a vacuum blower with lateral canals...

This conveying system is the least efficient, because it requires a higher volume of air to move the material from the pick-up point to the destination, in comparison to pressure conveying system...
