RainSystem AF 150 is an automatic rainwater utilisation system complete with a run-down tank and two self-priming pumps.

It is used in conjunction with cisterns or tanks for utilising rainwater and saving potable water in multi-family houses and small commercial applications.

It is supplied as a connection-ready module with compact construction, electrical and hydraulic connections already in place, mounted on vibration-insulated painted steel pipe frame.

The replenishment reservoir (hybrid tank) is 150L nominal capacity.

Key features / advantages

  • Low-noise due to multistage centrifugal pumps
  • IE2-IEC three-phase AC motor (≥ 0.75 kW)
  • All parts that come in contact with the fluid are corrosion-free
  • Maximum operational safety due to fully electronic RainControl Professional controller
  • High economic efficiency due to fresh water replenishment according to requirements
  • High reliability due to DVGW-certified, flow- and noise-optimised replenishment reservoir
  • Systems with three to six pressure boosting pumps on request or see chapter Wilo pressure boosting systems. Control of a single-phase cistern pump on request.
