Fuchs UmwelttechnikKFS

KFS Series

The KFS is a very compact extraction and filter unit designed for small-volume source capture applications. Fuchs describes it as “small in size, big in technology,” with an EC motor for continuous operation and automatic filter monitoring via differential pressure. The unit is especially suited for very small welding and inscription lasers, soldering fumes, and adhesive vapours.

Selection Notes

Use KFS where a very compact extraction unit is needed for low-volume fume or vapour capture.
Confirm that the required extraction volume falls within the 30–80 m³/h range.
Consider the 19˝ insert suitability when the unit must be integrated into compact machine or cabinet layouts.
Use the automatic differential-pressure filter monitoring as a maintenance planning aid.

Integration Notes

Place the extraction point close to the emission source whenever possible.
Confirm electrical supply requirements before specifying the unit.
Plan filter access so easy-change maintenance remains practical after installation.
Review application details such as contaminant type, duty cycle, and required capture geometry before final selection.
