Height-adjustable cover cap - LUWA®

Corrosion-free aluminum alloy with V2A cover flap, height-adjustable for swiveling away.

The GEFA LUWA system is used for the simultaneous watering and ventilation of the tree from just one opening. Thanks to the innovative technology of the filler neck, no water can get into the ventilation line and is thus directed purposefully into the root areas.

The new irrigation and ventilation system is used to optimally supply the root space in a planting pit, this new technology combines water and air supply at the same time.

The ingenious opening of the adapter not only provides ventilation but also irrigation. This "system separator" prevents accidental watering into the ventilation pipes. The water is directed specifically to the bale, the ventilation function is always fully functional regardless of the irrigation. The LUWA system connection can be combined with standard drainage pipes in DN 80 or DN 100.

Different variants can be used to cover the LUWA system. Individual solutions can be combined depending on the area of ​​application. Cast iron covers, for example, are suitable for drivable areas. Aluminum lids can be used for an elegant and simple integration into pavement areas that can be walked on. Requirement: Compatibility with DN 80 and DN 100.
