The transparent lid for the Vienna II filter housing is an original spare part that allows easy visual inspection of the condition of the pre-filter basket. Without the need to remove the lid, you can immediately see whether the pre-filter needs cleaning to restore full filtration flow.
The lid is made of a transparent material resistant to UV radiation, thanks to which it retains its transparency even after prolonged exposure to sunlight. The thread and dimensions exactly match the specification of the Vienna II filter housing.
We recommend replacing a cracked or cloudy lid without delay, as a damaged lid under pressure poses a risk of sudden water leakage. Installing the new lid is quick and requires no tools.
