Dry Separator
Inhaltsverzeichnis
Dry separators are mechanically filtering separators used for air contaminated with dry dust. Dry separators consist of a housing and filter elements (filter media, dry filters) installed inside. The dust-laden air is passed through the filter media (e.g., fiber, felt, or fabric filters). The airborne contaminants are separated by the filter media, with small particles primarily removed through diffusion, and larger particles increasingly through the barrier effect and inertia. There is a distinction between depth filtration (storage filters, non-regenerable) and surface filtration (regenerable filters, regeneration e.g., by compressed air pulses). If the air is not to be discharged outside but returned to the building, a HEPA (High Efficiency Particulate Airfilter) stage (particulate filter) can be added downstream.
To protect your employees and the environment from air contaminated with dust, we offer you a dry separator system tailored to your individual needs. From small units to large central systems, whether as a standalone solution or in combination with other processes, we are your competent partner and full service provider for air purification.

Frequently Asked Questions
For which applications is a dry separator suitable?
The dry separator (also Dust collector) is used for dry dust (non-sticky, non-adhesive, or abrasive).
What components make up the operating costs?
The operating costs of a mechanically filtering separator primarily consist of electricity costs (largely dependent on the fan’s power), maintenance costs, and replacement part costs (especially filter media).
What is the difference between a dry separator and a wet scrubber?
Dry separators are mechanically filtering separators that operate with filter media (e.g., fiber, felt, fabric filters). They are not suitable for sticky, tacky, or abrasive particles. Wet scrubbers operate with a washing liquid (usually water) and can also separate sticky, tacky, or abrasive particles as well as gaseous emissions. The operator must comply with Legionella regulations in this case.
