A rainwater filter for rough cleaning

The rainwater filter of a cistern is generally referred to as the first effective coarse filter. Above all, it serves to ward off the intrusion of small animals, leaves and plant parts. Downstream filter units ensure a finer postfiltering. The placement of the filters varies and can be done both in the cistern and on the supply lines.

Filter types and placements

As an ideal combination, you can work with a flow filter and a whirl filter. Together with a calm water inlet, these two filter units are enough to make rainwater suitable for use with utility water.
