The brushless motor at the heart of a Diamond Dryer makes it extremely durable. Brushless motors are also incredibly energy efficient, so hands are dried faster and cheaper. Another benefit of a brushless motor is there is less noise when in operation, which can be a problem with other high-speed hand driers.
The only maintenance a Diamond Dryer needs is a wipe with a soft cloth to keep it clean. There are no filters to change, no motor brushes to replace and drip trays to empty. Diamond Dryers simply work and they look great too.
