Customized HEPA/ULPA Filter Requirements:
In high-end manufacturing, standardized HEPA/ULPA filters often struggle to meet the complex and ever-changing application scenarios, from the anti-static requirements of semiconductor factories to the sterilization resistance needs of biological laboratories, and the extreme temperature adaptability required in the aerospace field. Different production environments necessitate different HEPA/ULPA filters.
Typical requirements include:
- Microelectronics industry: Requires ultra-low release filters to prevent contamination of precision circuits;
- Pharmaceutical companies: Requires verifiable sterilization compatibility and integrity;
- Food processing: Requires food-grade materials that meet FDA standards;
- Nuclear facilities: Must meet radiation protection and special safety standards.

Customer Case Studies
Case 1: Special Aerospace Requirements
Customized temperature-resistant HEPA filters were designed for an aerospace company near Munich, requiring stable filtration performance within a temperature range of -60°C to 250°C. The solution, using special adhesives and a stainless steel frame, passed 1000 temperature cycle tests.
Case Study 2: Energy Saving Retrofit for a Semiconductor Plant
Custom-designed low-resistance, high-efficiency ULPA filters for a semiconductor plant, reducing the initial pressure drop from 280 Pa to 180 Pa while maintaining 99.999% efficiency, resulting in annual energy savings of up to €120,000 per cleanroom.
Case Study 3: Safety Upgrade for a Biosafety Laboratory
Custom-designed a closed-loop replacement system for a biosafety level 3 laboratory, enabling zero-exposure filter replacement and protecting researchers from pathogen infection.
Case Study 4: Hygiene Optimization in a Food Factory
Developed an anti-oil-mist HEPA filter for a chocolate factory; its special oleophobic coating extends filter life by three times.
