HOW A KA FIXTURE WORKS

Approach

An infrared sensor reads a hand. There is no handle, tap head or flush button to touch.

Activate

A faucet delivers a controlled flow. A flush plate signals the concealed valve for a set volume.

Stop

Flow ends when the hand leaves, or when the flush volume is complete — water is not left running.

Sensor faucets

Three series. Deck cylinders, an arc spout, and a wall-mounted sensor spout.

Sensor flush systems

Four sensor plates for concealed flushing, including a marked 6L / 3L water-closet plate.

THE FAUCET RANGE

Three automatic taps.

Series B arc faucet, front view with sensor window and aerator

B · DECK FAUCET

Arc deck faucet

A squared arc spout with the sensor window on the front of the body and an aerated outlet. The clearest read of a public sensor faucet.

C · WALL SPOUT

Wall sensor spout

A tubular wall spout on a circular escutcheon. The sensor and black aerator sit together at the outlet, leaving the deck clear.

WHY KA / 優勢

Specified for rooms that stay open.

01
Zero-touch hygiene
Advanced touchless sensors enable completely hands-free activation of faucets and flushing systems. Eliminating contact with the fixture reduces germ and virus transmission in public restrooms.
02
Water and cost saving
Infrared sensors run water and flushes only when needed. KA states that systems can reduce water consumption by up to 70% compared with traditional fixtures.
03
Durable for high traffic
Robust, vandal-resistant materials and industrial-grade components are specified for continuous use in malls, universities and hospitals.
04
Easy maintenance
Modular layouts simplify routine cleaning, battery replacement and troubleshooting, so teams can service a busy restroom with less downtime.
05
Compliant in Hong Kong
Solutions are specified for Hong Kong WSD requirements, including WELS Grade 1 and GA certification, and for relevant mainland China standards — suited to public tenders and cross-boundary projects.
