SPECIFICATION NOTES:
Each bin compartment will support a 12-inch to 15-inch loader or vacuum receiver.
*
Throughput rates are based on using no more than 5% additive or colorant material total in either the CAF3 compressed
air or F03 auger feeder. Always refer to the selection guide for specific throughput information.
† The optional butterfly control flow control valve adds 3.5 in. {88.9 mm} to the total height. We recommend using the flow
control valve when mounting the blender to a stand, surge bin or hopper.
‡ Feeders will increase width and depth dimensions. Please refer to feeder specifications.
§ Each additional auger feeder requires an additional 1 amp @ 120V or 0.5 amps @ 240V.
