Product Description

Rainus Downpipe Filter - 3P Technik


Rainwater filter for installation in the lower section of the downpipe. It is easy to monitor due to its installation position in the downpipe. No need to lift heavy lids or to climb down into storage tanks, as required when filters are installed underground. This downpipe filter allows the cleaned rainwater to flow out down the filter pipe. Manufactured by 3P Technik.



Connection Capacity for roof areas up to 70m²


Max. Flow rate sieve insert approx. 0.6 l/sec = approx. 2m³ cleaned water per hour.


How it works:

1. The falling rainwater's energy is attenuated by baffles in the upper filter housing

2. Rainwater is then calmed in a small sump.

3. Water then weirs over the sump lip, and is distributed evenly across the primary cascade, the first cleaning step.

4. The primary cascade filters out any large or coarse particles, such as leaves and moss.

5. Below and behind the primary cascade is a finer secondary filter.

6. Fine and coarse particles are ejected from the front of the filter.

7. Cleaned rainwater flows out of the filter outlet to a storage tank or to the point of use or disposal system.
