Silo venting

Silo venting takes place during filling; the air comes out without dragging the product. Filtration also takes place in the reverse direction – during emptying – to protect the product from external contamination.

Filtration must therefore take into account the following specific parameters:

• product contained: type, granulometry, filling and withdrawal speed, food/pharmaceutical grade, etc.
• possible presence of contaminants, especially humidity (formation of condensation)
• possible presence of electrostatic charges
