GRAF Optimax Filter External

Providing a respectable 95% water yield, this self cleaning external filter system paired with an optional Opticlean cleaning unit will require almost no maintenance. With a variable installation depth from 22" - 41" you have the option to choose what best suits you; a pedestrian loading system comes standard which can be swapped out for one capable of vehicle loading (both can be locked). The 4" connections will cover a roof area of up to 3700 sq. ft., and the 6" connections will cover up to 8000 sq. ft.

• Minimal height offset (200 mm) between the inlet and outlet
• Very smooth surface and therefore max. self-cleaning, mesh wide 0.35 mm (0.01")
