Do I need a fan on my bin vent filter?

The objective of a bin vent filter is to remove the dust from the air entering the silo, either by way of pneumatic convey, flow promotion, or displaced by material stored in the silo.

The need for a fan on a bin vent filter will depend where the air needs to go once it’s cleaned.Bin vent filters are frequently located on the roof of a silo, in this case the air needs to only get to the other side of the filter.In this scenario, there is no need to blow the air any further.However, if the bin vent filter is located in a penthouse or a building where the discharged air will need to travel some distance to atmosphere, a fan or blower is recommended.
