8.Technical notes

By employing a mono-form design, the hand dryer blends into various shapes of architectural spaces.

By using an angular nozzle, the hand dryer reduces air blow back, making it more comfortable to use.

The joint of the hand insertion section has been reduced by half. It minimizes the clogging of dust in the joint, making cleaning much easier.

The hand insertion section, drain tank and drain hose are treated by an antimicrobial process, improving hygiene.
