Nilfisk AX400 And AX300 and Advance Aquaclean Stainless Steel Clean Solution Screen
Nilfisk AX400 and the Nilfisk AX300 and the Advance Aquaclean stainless steel mesh clean solution water screen. It fits in the clean water tank as a push fit into the water outlet in the bottom of the clean solution tank, that's the second photograph.
I've taken a photo of a screen from a working machine, don't worry, you'll get a brand new one!
If the cleaning solution is left in the tank for a few days, the chemical mixture can break down, and it can form a gel blocking this screen so the water or solution can't flow. This filter then needs to be washed off.
