Sluice filter system type SLF is a filter system for dust and wood chip aspiration systems. It is particularly well-suited for use in medium-sized companies where the air volume, as well as the amount of filtered material, is too extensive to apply a reasonable system of manual emptying procedures seen from a practical and a financial point of view.

The sluice filter system is an intermediate filter ensuring that the filtered material is not stored within the filter itself. Instead the mixture is transported to a special wood chip storage area (silo or container) by means of an emptying ventilator or stepless emptying procedures.

The filter system is produced with a filter area of 22.6 m2 to 181 m2, is it economical and environmentally friendly, and it is suitable for filtration of air volumes between 26,000 and 21,000 m3/h.
