  • Touchless wave-on sensor: wave the sensor without touch, water flows, wave again, water stops. Water stops automatically after 1min continuously flow.
  • Automatically adjusting the sensing distance.
  • Water-saving: Water-efficient faucet reduces overall water usage without sacrificing water.
  • Energy-saving: 4AA alkaline batteries shall last approximately 3000 times/month for one year.
  • Easy installation and cleaning.
  • Outside connected battery box for a convenient changing between AC,DC and AD.
  • Healthy and Safe: with the touch-free faucet, it can prevent the spread of bacteria and germs. It’s not only time-saving but also hygienic.


The single hole touchless faucet KEG-8906-D/A/AD has a chrome surface appearance.

More excitingly, the design of most touchless faucets is stylish and elegant to fit all basins,sink or lavatory, from classic to modern.

Yes, the touchless faucet is quite reliable. The technology of the infrared sensor is stable and developed for many years. Every KEGE touchless faucets are tested by life testing, valve on/off testing, infrared sensor distance testing and salt spraying testing. Sensor lifespan:500,000 times on and off, valve lifespan:1,000,000 times opening.

In the future modern smart homes, a touchless bathroom faucet is also one core part. They’re cool, for one thing, as their motion sensors always give you some sort of smart, modern techy feelings. Plus, a touch-free faucet keeps your fixture and bathroom clean, it’s a good hygienic choice and decreases the risk of contracting viruses and diseases.

Touchless faucets use infrared sensor technology that allows you to start the flow of water without touching the faucet. Instead, just placing your hand under the spout sensor, the sensor will give the solenoid valve a signal to open, then the water will start flow; When you take your hand away, the sensor will indicate the solenoid valve to close, then water flow will stop.

The touchless faucet needs electricity for sure. Both the sensor and solenoid valve works need electricity power. Normally three choices: DC 6V: 4xAA alkaline batteries; AC: using a transformer to transfer power from 220V/380V to 6V; Both DC/AC models existed, firstly use AC power to work, if AC no power then DC start to work.

6V with 4xAA alkaline batteries shall last approximately 3000 times/month for one year.

1. Battery issue: battery no power or battery installed in the wrong direction.
2. Sensor issue: the sensor got damaged, surface not clean or the waterproof cable connection issue.
3. Solenoid valve issue: the filter in the valve blocked or the valve is damaged.
