ACS Valves Aero-Flow Series rotary feeders

The Aero-Flow Series of rotary feeders is designed specifically for pneumatic conveying of dense materials such as fine powders used in chemical and pharmaceutical processing, food and bakery processing, plastics, and milling. It 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 pressurised 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 fluidisation process, improves material consistency and optimises 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.

ACS Aero-Flow feeder housings are available in cast iron and 304 or 316 stainless steel; in either 44 or 54 cm heights. They provide optimal service in applications with pressure differentials up to 15 psig and elevated temperatures to 260°C. The Aero-Flow Series 10-vane rotor is precision machined with bevelled vane tips and sides. Other rotor configurations include Teflon-coated and adjustable tips. Adjustable rotor tips are available in hardened steel or stainless steel. Rotor housing interior surface coating options include hard chrome, tungsten and Teflon.
