The PTF Open-Mouth Bagger is an automatic dual-spout system designed for quick and precise dosing of powders including a dust control system providing great cleanliness.

This bottom-up innovative filling system avoids free falling of the product since the vertical auger automatically fills the bag from bottom to top. The bag lowers as it fills thereby the auger is always close to the product line, reducing dust emission to a minimum.  The filling is done in two distinct steps: coarse and top-up fine filling allowing rapid and accurate target weights.

The PTF open-mouth bagger offers a simple and intuitive mode of operation which requires low maintenance while attaining precision and constancy standards.
