Operating principle

Rotary lock valves are used optionally instead of collecting containers on AL-KO dust extractors and extraction systems. Rotary lock valves transport the separated material continuously and without pressure into a container, big bag, etc. provided by the customer. Since this happens continuously, there is no interruption in the extraction.

Your benefits
  • Uninterrupted operation of the extraction system, since no collecting containers have to be emptied
  • No loose material in the extraction system, therefore reducing the risk of fire and explosion
  • Collection of separated material in containers of your choice
  • Tested in accordance with ATEX product directive 94/9/EC
  • For large quantities of materials that require continuous extraction
  • For dry and free-flowing materials (wood, plastic, metal, etc.)
Options & variants
  • Version with blow-off attachment for transport of the discharged material
  • Mounting option on round discharge
  • Application-specific custom version is possible
