The BFC-RD300 rotary feeder (also called a rotary airlock or star feeder) is a rotating vane wheel that discharges bulk powders and granules from hoppers while maintaining an air seal. The 300 mm diameter rotor with 8 pockets rotates at controlled speed to deliver uniform, metered discharge. Used extensively in pneumatic conveying systems, dust collectors and powder processing where air pressure isolation is required. The cast iron or stainless steel body with replaceable tips provides reliable, dust-tight operation.
