Every time someone touches a water boiler tap, there's a chance that any germs on the user's hands could be transferred to the next user. The Buffalo hands-free tap adaptor has been designed to remove this altogether. By simply placing the adaptor on top of an existing Buffalo manual fill water boiler tap, there's absolutely no need for anyone to touch the appliance with their hands. The adaptor uses a clever levering mechanism which activates the tap by simply pushing a cup against the stainless steel adaptor. A great solution for reducing the spread of infection.
