Spring grinding generates particulate emissions which are not avoidable even in the use of state-of-the-art machinery. The capture, extraction and separation processes involved in production are regulated for operational and occupational safety and environmental protection reasons. The handling of fine dust is further complicated by the presence of toxic and carcinogenic health hazards. Increasing requirements for energy efficiency set additional demands that must also be taken into consideration.
Dry separators in the VARIO or PT series are optimally suited for the extraction of dust from spring grinding processes. The KLR filters are equipped with a PTFE membrane to achieve a residual dust content of < 0.1 %, and enable clean air recirculation of purified air into the workplace without additional secondary filters. This substantially contributes to increased energy efficiency. However, the TRGS 560 regulation regarding air recirculation must be followed. The continuous compressed air cleaning of the filters ensures continuous operational safety.
These customers rely on our extraction systems during spring grinding.
