    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.
