OPERATING PRINCIPLE
The Airdep gravel filter FG series ensures the simple coarse cleansing of the biogas. The gas flows through a gravel filter layer during which process dirt, foam and condensate droplets are separated out. Filling material is usually coarse gravel with granular size between 30 and 60 mm. An external water trap device allows for continuous disposal of condensate.
