Pre-separators are used for large quantities of material to relieve the main filter. In the case of explosive media, they serve as a spark trap to prevent potential fires and explosions.

Processes:

• Welding
• Grinding
• Polishing
• Lasering
• Deburring

Media:

• Explosive dusts
• Gases and fumes
• Abrasive materials
• Oils and emulsions

To give you an overview, we will briefly show you the advantages and disadvantages of the different designs.

Separate pre-separators:
+ Maximum separation efficiency
– Higher acquisition costs

Side pre-separator:
+ Space-saving and cost-effective
– Lower separation efficiency

Water pre-separator:
+ Suitable for glowing particles with high energy
– Shorter filter service life, higher disposal costs

Spark trap:
+ Reduced energy consumption, cost-effective, easy to retrofit
– Lower separation efficiency

When planning your pre-separator, we carefully consider the following criteria:

1. Type of material: abrasive, adhesive, statically charged, oily/sticky or explosive
2. Particle size and weight: in L/day (liters per day)
3. Material volume and weight
4. Processes
5. Cyclone size: depending on the air volume and the required extraction power

We offer the following options for adapting the appropriate discharge to the material quantity:

Rotary valve:
– Suitable for continuous material flow
– Precise dosing and control of the material discharge

Big Pack:
– Ideal for larger quantities of material
– Offers an efficient and space-saving solution for disposal

Bucket 15/30 L:
– Suitable for smaller quantities of material
– Easy handling and emptying of the buckets

Closed container/container:
– Safety aspect for explosive or hazardous materials
– Effective storage and disposal of large quantities of material

The selection of the appropriate discharge depends on the specific material quantity, the process requirements and the safety regulations. We will be happy to help you find the optimum discharge solution to meet your requirements.
