A WRAS approved tap, the Franke Aqua131 or Aqua135 is an attractive piece which supplies cold or premixed warm water to the user without physically touching the tap. The difference in models is a choice of battery or mains power source. A theft proof aerator with integrated flow regulator assist a low water flow rate of 6 lpm, ideal for water saving during each use. Made from brass with a solid polished chrome plated finish, it comes complete with durable, vandal resistant properties.

The Water Supply (Water Fittings) Regulations or Scottish Byelaws require that a water fitting should not cause waste, misuse, undue consumption or contamination of the water supply and must be of an appropriate standard.  The WRAS approval gained by this tap demonstrates complete compliance with this.

For peak performance the recommended water pressure used with this tap is 3 bar. However, there’s a degree of flexibility to suit a host of locations with a minimum and maximum water pressure range between 1bar and 10bar.

A hygiene flush clears out any stagnant water left in the system after a period of 24hours of non-use.  This 10 second flow can be set on or off depending upon the location’s requirements.

The sensor can be programmed to detect either a static or a moving object. This allows for specific differences in washroom locations for things like reflections from washbasins.

The tap will show information such as status of the hygiene flushing and last flush-process in hours.  Idea for facilities managers to monitor servicing requirements.

To prevent vandalism and misuse, the tap will only run for 60 seconds of continuous activation.
