Rainwater filter for larger roof areas. Filter for installation in concrete ring or other structural chamber (Ø 2000 or Ø 2500 mm). The filter can be delivered directly to site, or pre-fitted off-site. The proven 3P two-step Volume Filter cleaning system gives a high level of filtering efficiency, independent of flow rate. Due to the steep inclination of the two step filter cartridge, the filtered out debris is continuously washed away to sewer. The sewer outlet is installed within the chamber wall. The filtered out material falls to the base of the chamber and is washed away during the next intense rainfall event.

Connection capacity according to DIN 18481:
3933 m² roof area at rainfall intensity of 300 l/(sxha).

A larger area can be connected using a bypass-installation.

Maximum flow rate of filter sieve:
18 l/sec = 64,8 m³ clean water per hour.

Inlet rainwater: DN 300
Outlet to storage: DN 250
Outlet to sewer: DN 300

Height difference between inlet and outlet: 600 mm, DN 300 KG elbows are supplied for mounting in concrete ring.

The filter should be cleaned depending on the contamination loading 1 - 2 times during the year.

1. The incoming rainwater is backed up and is then equally distributed across the cascades = principle of overflow

2. Pre cleaning through the cascades, coarse dirt particles are led across the primary filter cascades directly to the sewer

3. Pre-filtered water then flows over the secondary filter sieve (Mesh size 0,390 x 0,980 mm), due to the special mesh structure of the sieve, any dirt is led directly into the sewer, therefore low maintenance intervals

4. Cleaned water is led into the cistern

5. Dirt goes to the sewer
