SILOSAFE – Cartridge Dust Collector for Storage Silo Ventilation

SiloSafe is a compact cartridge dust collector specifically designed for the ventilation and venting of pneumatically filled storage silos.

During pneumatic filling operations, the dust-laden air introduced into the silo generates an increase in internal pressure, which must be controlled to prevent uncontrolled emissions and overpressure.

The SiloSafe filter allows controlled air venting, effectively retaining the dust and allowing it to fall back inside the silo, preventing material dispersion and environmental contamination.

Thanks to Nederman’s patented UniClean technology, the system ensures high filtration efficiency, optimised cartridge cleaning and long filter element service life, even in the most demanding applications.

SiloSafe – Operating principle

During pneumatic filling of the silo:

dust-laden air is conveyed to the venting filter;
solid particles are retained on the outer surface of the filter cartridges;
filtered air is discharged into the atmosphere in compliance with emission limits;
the compressed-air reverse jet cleaning system periodically removes the dust;
the filtered material falls directly back into the silo, preventing product loss.

Typical applications of the SiloSafe filter

The SiloSafe filter is designed for silo venting applications in plants with pneumatic conveying of bulk materials, including:

cement silos and concrete batching plants
powder dosing and distribution systems
mineral silos and quarries
chemical and plastics industry
food and animal feed industry
foundries and metalworking
storage of industrial dusts and bulk materials

Safety and operational reliability

SiloSafe is designed to operate on silos handling potentially explosive dusts and is suitable for use on ATEX-certified vessels.

Its robust mechanical construction contributes to the structural protection of the silo during pneumatic filling operations, ensuring operational continuity and safety.

Operational benefits

Installing a SiloSafe venting filter allows you to:

control the internal pressure of the silo
reduce dust emissions
fully recover the filtered material
improve system reliability
reduce maintenance and operating costs
ensure continuity of the production process
