Safe dedusting for silos and storage containers

Filtration solutions for venting and dedusting when filling, emptying and storing bulk materials in silos

During the filling and emptying of silos, considerable amounts of dust are generated - especially during the pneumatic conveying of powders and granulates. Due to the displacement air during material feed and pressure differences during discharge, the air must escape in a controlled manner without releasing dust particles into the environment.

Silo filters with continuous cleaning completely separate product dusts, enable unpressurised silo operation and protect against uncontrolled emissions. They ensure ATEX-compliant ventilation for combustible dusts, fulfil TA Luft requirements and ensure process-stable storage conditions.

Our filter systems are compact, pressure shock-resistant, low-maintenance and suitable for a wide range of bulk materials and silo types. Whether as a top-mounted filter with automatic cleaning or as an external dedusting unit, we offer ATEX-compliant, high-performance solutions for safe and clean silo and container operation.

We filter

Typical areas of application for silo ventilation

Pneumatic silo filling via tankers or conveyor lines:
Dedusting of the displacement air when powders and granulates are introduced

Silo ventilation for mechanical feeding:
Filtration of fine particles when air is displaced by gravitational forces

Dedusting on storage silos and storage containers:
Dust extraction during continuous ventilation

Ventilation during silo discharge:
Prevention of dust escaping during product discharge

Pressure shock-resistant filter solutions in ATEX zones:
Filtration for explosive bulk solids

Multi-chamber silos with central ventilation:
Dust separation at manifolds or distribution points

The benefits of our filter systems for silo ventilation

Product quality & silo safety

  • Clean separation of product dust from displacement air
  • Protection of the silo against pressure damage
  • Return of separated particles back into the silo
  • Economical utilisation of raw materials due to high separation efficiency

 

Process stability & reliability

  • Pressure equalisation prevents overpressure and underpressure in the silo
  • Continuous venting even during storage downtimes
  • System lifetimes of up to 30 years
  • Constant and reliable filter performance for trouble-free continuous operation

 

Explosion protection & occupational safety

  • Reduction of dust concentrations in the air and contamination during operation
  • Protection against dust explosions with ATEX-compliant dust extraction solutions
  • Compliance with occupational health and safety and environmental protection requirements
  • Explosion protection concepts for hazardous areas

 

Efficiency & economy

  • High quality and process reliability
  • Guaranteed product consistency
  • Minimal maintenance effort
  • Maximum system availability
