VF1

SPEL volume filter vf1 banner

A two step cleaning system, with high level of filtering efficiency, independent of flow rate.

Features

SPEL Volume filter VF1
  • Frost resistant.
  • Self cleaning. Low maintenance intervals, filter insert is easily removed for cleaning and does not have to be changed.
  • Optional dirt retention basket can be supplied.
  • Connection capacity according to DIN 1986 for roof areas up to 350 m².
  • Max. Flow Rate Sieve insert 1,5 l/sec = 5,4 m³ cleaned water per hour.
  • Height difference between inlet and outlet just 300 mm.
  • The filter has to be cleaned depending on the contamination 1 - 2 times during the year.

How it works

  1. As water arrives the level builds up and is equally distributed across the cascade.
  2. Pre cleaning through the cascades. Largest 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 0,65 mm). Due to the special mesh structure of the sieve, any dirt washes directly into the sewer which means the filter is self cleaning, with very low maintenance.
  4. Cleaned water flows to the cistern.
  5. Dirt goes to the sewer.

Twin Filter

SPEL Twin Filter banner

The SPEL Twin Filter can be installed in a pilot shaft or in frost-protected regions directly on the wall. Normally standard concrete shafts are used (Ø 1000 mm). The filter can be delivered to the site pre-installed in the shaft.

Features

  • Connection capacity for roof areas up to 700 m².
  • Max. Flow Rate Sieve insert 3.0/sec = 10,8 m³ cleaned water per hour.
  • Rainwater inlet: 2 x DN 100/ DN 150
  • Tank inlet: 2 x DN 100/DN 150
  • Outlet into sewer: 2 x DN 100/ DN 150

How it works

SPEL Twin Filter how it works
  1. As water arrives the level builds up and is equally distributed across the two cascades.
  2. Pre cleaning through the cascades. Largest 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 0.65 mm). Due to the special mesh structure of the sieve, any dirt washes directly into the sewer.
  4. The cleaned water is being absorbed in the middle tank and directed through one or the two connections into the storage.
  5. Dirt goes to the sewer through the shaft.

VF2

SPEL Volumefilter VF2

Features

  1. Rainwater filter for bigger roof areas. Filter for installation in a concrete ring (Ø 1000 mm). Normally standard concrete shafts are used. The filter can be delivered to the site yet pre-assembled in the shaft.
  2. Relative connection capacity according to DIN 1986 for roof areas up to 850 m². Because of a Bypass-Installation a bigger area can be connected.
  3. Max. Flow Rate Sieve insert 3.0/sec = 10.8 m³ cleaned water per hour.
  4. Inlet rainwater DN 200
    Outlet into tank DN 150
    Outlet into sewer DN 200
    Height difference between inlet and outlet 320 mm.

How it works

  1. As water arrives the level builds up and overtops the filter lip, so ensuring it is distributed evenly across the whole width of the filter cascade.
  2. Pre cleaning through the cascades. Largest 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 0.4 x 1 mm). Due to the special mesh structure of the sieve, any dirt falls directly down onto the bottom of the shaft. In case of heavy rainfalls, the filter has more loss, as the water washes away the filtered dirt into the sewer.
  4. The cleaned water is being absorbed in the lower tank and directed through a tube DN 150 into the storage.
  5. Dirt goes to the sewer through the shaft.

VF12

SPEL Volumefilter VF12

Features

  1. Rainwater filter for bigger roof areas. Filter for installation in a concrete ring (Ø 2000 or Ø 2500 mm). The filter can be delivered directly to site, or pre-fitted off-site.
  2. Connection capacity according to DIN 18481: 3933 m² roof area at rainfall intensity of 300 l/(sxha).
  3. Maximum flow rate of filter sieve: 18 l/sec = 64,8 m³ clean water per hour.
  4. Inlet rainwater DN 300
    Outlet into tank DN 250
    Outlet into sewer DN 300

How it works

  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
