Preshaping fan

Preshaping fan

The pre-forming blower shapes the Big Bag before filling.

This system facilitates the filling of Big Bags.

The pre-forming of the Big Bag is carried out using outside air, which is then blown into the Big Bag by a centrifugal blower. In cases where the product to be conditioned in the big bag must not be contaminated, it is advisable to install a box with filters upstream of the pre-forming fan. The air drawn in by the fan is then cleaned by this filter box. The filtered air is then redirected to the big bag former before filling.
