Rainwater filtration – reliable system protection

The external filter for a d400 well is a key element of a rainwater harvesting system. Using it allows for effective cleaning of water from impurities such as leaves, branches, sand or moss before it reaches the tank. This makes the water suitable for technical purposes – watering the garden, flushing toilets or washing. This filter is particularly useful in areas with high rainfall and dense vegetation.

The external GRAF filter, designed for installation in wells with a diameter of 400 mm, is characterized by a solid construction and easy installation. Made of high-quality materials resistant to weather conditions and corrosion, it ensures long-lasting and trouble-free operation. The threaded cover allows convenient access to the filter basket for cleaning and maintenance.
