Hygienic Dust Collection Units
High-Efficiency Dust Extraction Solutions for API, Solid Dosage and Pharmaceutical Processes
Hygienic Dust Collection Units, are specialized filtration systems used to safely control dust loads generated in pharmaceutical manufacturing, API processing, solid dosage processes and sensitive production areas requiring high containment.
These systems can be configured for process needs with goals of operator safety, preventing product contamination, reducing explosion risk, safe filter replacement, long filter life and high filtration efficiency.

High Containment
It provides a closed-system approach designed to reduce operator exposure in API and pharmaceutical processes.
H13 Filtration Grade
High-efficiency surface filtration can be achieved with a multilayer filter structure featuring an ePTFE membrane.
Long Filter Life
With the right filter configuration and automatic cleaning control, filter life can be extended under suitable conditions.
What Is a Hygienic Dust Collection Unit?
A hygienic dust collection unit is a specialized dust extraction system that provides closed, controlled filtration of fine dust released in pharmaceutical facilities, API processes and industrial applications requiring high hygiene.
The core objective of these systems is to protect employee health, prevent product contamination, reduce explosion risk, control dust release during filter replacement and maintain high hygiene levels in the production area.
Key Technical Features
High-efficiency surface filtration with a multilayer ePTFE membrane filter medium.
A primary filtration approach at H13 level can be implemented.
Operator safety can be supported through Bag-In / Bag-Out filter replacement and a closed maintenance concept.
The filter surface can be restored in a controlled manner through rotary nozzles and compressed-air cleaning.
Safety can be enhanced through flame arresting, a dissipative filter structure and static-electricity control.
Under suitable process conditions and with correct cleaning control, filter service life can be extended.
Technical Configuration of a Hygienic Dust Collection Unit
Multilayer Filter
The ePTFE membrane promotes surface filtration by reducing fine-dust penetration into the filter depth.
Closed Filter Replacement
The Bag-In / Bag-Out approach can reduce dust release and operator exposure during filter replacement.
Rotary Nozzle Cleaning
Compressed-air cleaning can be distributed more uniformly through rotary nozzles directed at the inner filter surface.
Intelligent Cleaning Control
By monitoring the filter operating point, the cleaning interval and filter condition can be managed dynamically.
Filtration and Containment Approach
In pharmaceutical processes, a dust collection system must be designed not only to capture particles, but also to protect operators during filter replacement, maintenance, product changeover and cleaning. A closed-system approach is critical, especially for API and highly active substances. For the official ATEX framework, see Directive 2014/34/EU.
Intelligent Explosion Protection
Fine organic dust generated in pharmaceutical and chemical processes can create an explosion risk when suitable concentrations and an ignition source are present. Therefore, hygienic dust collection units must assess explosion pressure, flame propagation, static electricity and hybrid-mixture risk as carefully as their filtration grade.
Controlling flame propagation at the primary filter stage can reduce risk in the downstream clean-gas section.
A structure that reduces electrostatic charge build-up helps lower the risk of spark-induced ignition.
Mixtures with low MIE values containing dust and solvent vapour require a dedicated ATEX assessment.
Optimized Filter Cleaning
In hygienic dust collection units, the filter cleaning system is crucial for lowering maintenance costs and extending filter life. Retaining dust on the filter surface makes compressed-air cleaning more effective.
Multilayer Filter Medium
The multilayer ePTFE membrane filter medium reduces fine-dust penetration into the filter depth. This enables easier regeneration of the active filter surface by compressed-air cleaning and helps maintain filter performance for longer.
Applications
Key Considerations When Selecting a Hygienic Dust Collection Unit
Containment Level
API activity, OEB level, the operator exposure limit and the filter-change method are decisive in system design.
Dust and Explosion Parameters
MIE, Kst, St class, Pmax, hybrid-mixture risk and the possibility of electrostatic charging must be included in the ATEX assessment.
Cleaning and Maintenance
The filter-cleaning method, filter life, Bag-In / Bag-Out requirement, maintenance access and cleaning validation must be considered.
