3P retention &
infiltration filter

with telescopic extension

Article no. 1000626

Rainwater filter with integrated dirt trap for installation in front of the rainwater storage tank. Equipped with a sliding plastic shaft. This allows the telescopic extension to be easily adapted to the height conditions during installation on site. If required, the telescopic extension can also be shortened. It is also possible to stack several extensions on top of each other. The stainless steel dirt collection basket is mounted in the housing so that it can be easily removed using the removal rod.

The 3P retention and infiltration filter is ideal for systems that use the cleaned rainwater for the toilet, washing machine and garden irrigation and where the excess water must be infiltrated on the property because no sewer connection is possible to drain off excess rainwater or the excess water may only be discharged into the sewer via a retention throttle.
