Does my silo need a bin vent filter?

In most cases a silo requires a bin vent filter to ensure dust does not escape from the silo during filling. The size and type of filter used is dependent on the rate and method of filling as well as the material being stored. The filter must be sized to allow all of the displaced air (and conveying air if loading pneumatically) to be vented from the silo without over-pressurizing the silo. Over-pressurization of the silo will cause the relief valve to open releasing dust into the atmosphere and in extreme conditions, could result in damage to the silo.
