Patent 7334742 was granted and assigned to Airbus Deutschland GmbH on February, 2008 by the United States Patent and Trademark Office.
The present application describes a spraying device with droplet hold-back. The droplet hold-back is formed by a baffle, which collects the droplets in a defined volume. From this volume, the droplets can be suctioned by means of a suction opening and supplied to a filter system for purification. In this manner, a purified air can be supplied again to the surrounding air.
