Blind insert made of stainless steel. The blind insert is used in place of the regular filter insert in the WISY rainwater filters. It provides direct flow of the incoming water to the sewer or infiltration. This may be necessary in winter, for example, if the rainwater tank is to remain dry, or to prevent further water inflow during maintenance work on the tank.

Blind inserts are available for the following WISY filter designs :

  • FS filter collector
  • STFS standpipe filter collector
  • RS rain collector
  • (for all three filter types: height 17.5 cm, suitable for all downpipe diameters).

  • Garden rainwater collector GRS height 10.5 cm, suitable for all downpipe diameters
  • Vortex fine filter WFF 100 height: 15.5 cm
  • Vortex fine filter WFF 150 height: 21.5 cm
  • Vortex fine filter WFF 300 height: 27.5 cm

Blind inserts for rainwater filters

The blind insert deactivates the filter function of the rainwater filter. The stainless steel blind insert is the ideal solution if the cistern or rainwater tank is to remain dry. For example, during maintenance work or in winter, all incoming rainwater is channelled directly to the sewer or infiltration system. Instead of the regular filter insert, the blind insert is simply inserted to block the flow of water to the rainwater tank or water container.
