RainSystem AF 400 is an automatic rainwater utilisation system with run-down tank container and 2 non-self-priming pumps.

It is used for commercial and industrial rainwater utilisation applications to conserve potable water as a hybrid system in conjunction with rainwater storage tanks or vessels.

400L nominal capacity replenishment reservoir (hybrid tank).

Supplied as a compact, connection-ready module mounted on a vibration-insulated baseplate.

Key features / advantages

  • Low-noise due to standard multistage centrifugal pumps
  • All parts that come in contact with fluid are corrosion-free
  • Highest operational reliability thanks to fully-electronic Rain-Control Hybrid controller
  • High economic efficiency due to needs-based fresh water replenishment
  • High reliability thanks to flow- and noise-optimised overall concept
  • Automatic control of the feeding pump
  • System / level control in the low-volt range
  • Approved according to the quality specifications of the RAL quality standard GZ 994
