Reliable for sterile air and cleanrooms

Multi-stage Viledon air filtration systems

High-tech demands maximum purity. The tightest manufacturing tolerances and absolute precision in the production of semiconductors or nanoprocessors can be achieved only under cleanroom conditions. The pharmaceutical industry also requires the same high demands on air purity in the production of pharmaceutical drugs and active ingredients. It uses special safety zones for certain production steps, protecting the product from contamination.

High air purity is the essential requirement for sensitive controlled technical processes. Cleanrooms are used as they ensure a low-particle or, when necessary, a low-germ environment. The multi-stage Viledon filter concept can filter particles and harmful germs from the air in a reliable and energy-saving way. The principle is simple and efficient: well-matched filter stages with Viledon air filters of various filter classes and designs.

Usually a two-stage prefiltration consisting of Viledon pocket filters and cassette filters removes coarse to fine particles. Not only are these air filters highly effectively, they also have excellent energy efficiency values according to EUROVENT. The combination of a high dust holding capacity and low pressure drop curves results in low energy consumption and a reduction in CO2 emissions with controlled fans.

Viledon EPA, HEPA and ULPA filters are used as a final filter stage. They are responsible for reliably arresting finest particles and germs and can be used in cleanrooms with turbulent or low-turbulent airflow.
