Abstract
A lavatory system includes a hand dryer with at least a first proximity sensor and a second proximity sensor to detect an object for drying. A controller is communicatively linked to the first and second proximity sensors. The controller activates a drying operation after a first delay period if the first proximity sensor first detects the object for drying and activates a drying operation after a second delay period if the second proximity sensor first detects the object for drying. A filter flow sensor may also be provided to ensure proper filtering of the dryer's air.
