Food grade – piFLOW®f

This is a conveyor widely used in the industry where food grade quality is a demand. It has a high throughput performance as well as a small foot print. This conveyor is often used as an alternative to mechanical conveyors when there is a requirement for dust free conveying or low maintenance. Another advantage is that the pump is based on COAX® technology which is the most energy efficient way to produce vacuum. Capacity up to 4 tons/h.
