Designed specifically for pneumatic conveying of dense materials, the Aero-Flow™ Series of rotary feeders from ACS Valves provides highly efficient, air-assisted, material introduction to pneumatic conveying systems. The ACS Aero-Flow™ Series of rotary feeders uses a proprietary, dual-induction endplate design to introduce pressurized air from both endplates into the rotor pockets carrying process material. The high bulk density material, when mixed with air, is more effectively released from the rotor pockets and is more efficiently introduced to the pneumatically conveyed material flow. The Aero-Flow™ Series dual-induction design speeds the material fluidization process, improves material consistency and optimizes feeder energy consumption when compared to conventional, single-induction feeder designs. Further energy efficiency is provided by an available ACS variable frequency drive to modulate the feeder drive speed and reduce power requirements based on the fluctuating performance needs of the system.
