Volumetric feeders are basic design feeders for a variety of powders, from commonly used powders to adhesive or cohesive powders. They are extremely reliable machines to realize high accuracy and precision feeding. We have various original products depending on the physics of powder, feeding rate, and required specifications.


The FS model is a very reliable feeder for general powder as well as cohesive and strongly adhesive powders. The highly accurate feed rate is within +0.5 to 1.0% in volume for feeding rate ranging from 0.5 L/h to 100 m3.

*1Please contact us to select the right model for your inquiry. The required feeding rate capacity is different depending on the physics of your supply material.
*2 Air consumption (1) refers to dry air for impeller blowing and (2) refers to the pneumatic transportation of powder. The latter number is for reference. It can be variable due to the transportation distance and mixing ration.
*3 The air consumption for multi-direction type is the table value times number of discharge gates.
