Silo Vent Filters
Compact Filter Solutions for Safe Dusty-Air Discharge During Silo Filling
Silo Vent Filters, are compact dust filtration units that filter dusty air generated during silo filling and safely discharge it outdoors.
They are used especially in concrete plants, cement silos, bulk powder storage systems and pneumatic filling lines for low emissions, low energy consumption and safe silo operation.
Compact Design
Its compact housing fits easily on top of a silo and enables practical use in confined spaces.
Mechanical Cleaning
Filter elements can be cleaned automatically by a mechanical cleaning system that reduces the need for compressed air.
Low Emissions
With the appropriate filter element, the amount of dust released to the environment during silo filling can be minimized.
What Is a Silo Vent Filter?
A silo vent filter filters dust-laden air released from the silo during filling and allows clean air to be discharged outside. Dust particles are retained on the filter elements and, after cleaning, returned to the silo.
This maintains pressure balance inside the silo, reduces dust emissions to the environment and makes filling safer.
Key Technical Features
Vertically arranged, high-efficiency filter elements.
Compact, durable housing designed for mounting on top of a silo.
Electrically controlled mechanical filter cleaning system.
Differential-pressure monitoring and automatic function management can be implemented.
Monitoring and control integration can be provided through Modbus RS485 infrastructure.
For suitable applications, dust emissions below 1 mg/Nm³ can be targeted.
Silo Vent Filter Operating Principle
Dusty air generated during silo filling is directed into the filter housing.
Dust particles are retained on the filter elements, while clean air is discharged outside.
The mechanical cleaning system removes dust from the filter surface.
The removed dust falls back into the silo, reducing product loss.

Get Information About Silo Vent Filters
Silo vent filter selection should be evaluated according to silo volume, filling rate, product type, dust characteristics, emission target, installation space, maintenance access and control needs.
