Selection Notes

Use KKF where extraction requirements fall within the 30–335 m³/h range.
Consider KKF for small laser, welding, soldering, solvent, or adhesive vapour applications.
Use the LED filter-saturation indication and automatic filter monitoring as maintenance planning aids.
Specify the blower configuration around the application’s extraction volume and pressure requirements.

Integration Notes

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