Article description

The fine-mesh protection for pumps against damage-causing impurities:

The Einhell 12 cm pre-filter is a robust protective mechanism for garden pumps, domestic waterworks and automatic domestic water systems against damage-causing impurities. The integrated fine filter with a mesh width of 0.2 millimeters is washable, easy to remove and easy to change. The pre-filter has a ventilation screw, a brass female thread (33.3 mm) and a transparent filter housing. The maximum recommended working pressure is 5.5 bar. The temperature of the liquid fed through must not exceed 35° degrees. Delivery contents a double nipple with a 33.3 mm (1" male thread) and an adapter fitting with 33.3 mm (1" male thread) / 42 mm (1 1/4" female thread).

Easy to clean: take it out, rinse it out and the job is done. The filter element is easy to remove and can be cleaned with clear water. The fine filter fabric on the inside should not be damaged whilst cleaning. Cleaning frequency is dependent on the amount of dirt particles in the water.
