A silo vent filter separates entrained dust from air displaced during filling or material movement. This article focuses on applications and selection. Explore the TECHFLOW Tuff-Vent® range for product options.
Why Use Silo Vent Filter?
Typical duties include venting powder-storage silos and bins. The equipment must be selected for the material and the peak air flow, including the changing air-to-material conditions towards the end of a pneumatic delivery.
Features of Silo Vent Filter
Filter media, filter area, cleaning method, mounting and material discharge depend on the duty. A fan-assisted arrangement is an option for suitable applications, not a feature that every silo vent filter necessarily requires.
Applications & Advantages of Installing Silo Vent Filter
A vent filter is part of the overall filling arrangement. It does not replace independent pressure protection, level controls or an assessment of combustible-dust hazards.
Check access for inspection and element replacement, weather exposure, cleaning-air requirements and the interface with the silo structure. Establish the design information before choosing a standard unit.
A filter cannot be assumed to prevent fire or make a silo pressure-proof. Queensland’s silo-pressure safety bulletin describes incidents involving filters and pressure-relief systems.
