Article description

Fine-meshed protection for pumps against harmful dirt: the Original Einhell 25 cm pre-filter is a robust protective device to prevent garden pumps, domestic water systems and automatic water pumps from being damaged by dirt. The integrated 0.2 mm-mesh fine filter is washable, easy to remove and easy to change. The pre-filter has a bleed screw as well as a strong and durable brass internal thread (33.3 mm) and a transparent filter housing. The maximum recommended working pressure is 5.5 bar, and the pre-filter is suitable for a maximum flow rate of 4300 litres per hour. The temperature of the liquid flowing through must not exceed 35 °C. The kit includes a double nipple with a 33.3 mm (1") external threaded and an adapter fitting with 33.3 mm (1") external / 42 mm (1 1/4") internal threads. The filter insert is easy to remove and rinse with clear water for cleaning. The fine filter fabric inside must not be damaged. The time between cleanings depends on how dirty the water is. The pre-filter is compatible with all surface pumps without an integrated pre-filter and which have a 33.3 mm (1") externally threaded connection (intake side).
