Lean Phase Pneumatic Conveying Systems

We can offer pressure or vacuum systems in configurations to suit precisely your process requirements.

The conventional lean phase pneumatic conveying system uses a blower. metering valve, conveying pipeline, receiver and vent filter and can operate at higher pressures than vacuum conveying systems, resulting in higher conveying rates per pipe size

Pressure conveying

The basic pressure conveying system employs a blower, an air locked metering device at the inlet; a pipeline; receiver; vent filter.

Vacuum conveying

The basic vacuum conveying system employs a metering device at the inlet; a pipeline; receiver; vent filter and an exhauster.

Closed loop conveying

The closed loop system of conveying in a sealed circuit of pipe has distinct benefits for conveying hygroscopic and hazardous products. Benefits include conveying in dry or inert gas with minimum loss, and confinement of toxic products. Operating limits are similar to those for lean phase pressure conveying.
