Plastic Flowmaster Hoppers

Patent: US 7,475,796 B2


All Flowmaster hoppers are molded with an extra thick 0.500” heavy duty wall for a longer lasting, more durable container. Molded from High Density Polyethylene (HDPE), the hoppers are corrosion and chemical resistant with superior impact strength and puncture resistance. One piece hopper construction and seamless interior improves material flow characteristics. Flowmaster Plastic hopper bins are available in a variety of design configurations to meet specific dry handling requirements. Choose from Closed Top or Open Top volume capacities of 25 Cu. Ft. to 80 Cu. Ft. and hopper slopes of either 45° or 60° degree angles.
