The HEPA filter extraction units are designed for efficient extraction of fine dust generated during the milling of printed circuit boards (PCBs). These systems provide a high level of filtration with integrated HEPA filters that capture up to 99.97% of particles as small as 0.3 micrometers, protecting the working environment from harmful dust particles and ensuring safe working conditions. Extraction units are often equipped with multi-level filtration systems, including pre-filters to capture larger particles, extending the life of the main filter and increasing overall extraction efficiency. These systems are an indispensable part of modern manufacturing and development sites where the focus is on a clean environment and protecting the health of operators.
