The Primary Efficiency Layer is the first stage of filtration in the AtomStack D4 system. It is designed to capture larger dust particles and debris generated during laser cutting and engraving.
As the first filtration stage, it helps prevent premature clogging of the deeper filter layers by capturing larger particles before they reach the finer filtration stages.
This helps maintain stable airflow, improves the overall efficiency of the filtration system and contributes to extending the service life of the subsequent filters.
