Graf Optimax Pro rainwater filter

The Optimax-Pro rainwater harvesting filter is offered for the installation in underground tanks. The filter combines an extremely low height offset of just 165mm with a water yield of over 95%.

The main attraction of the Optimax-Pro is its compact design with a height offset of just 165 mm between the in and outlets and its convenient transparent cover. This not only ensure easy checking of the filter in its closed state - it also supports the filter insert. This means the complete unit of cover and filter insert can be removed from the filter in one easy step. Even more convenience is available here as an option: using an extended handle you can access the filter directly underneath the tank cover. Dirty clothing from checking the filter system should finally be a thing of the past.
