A device for protecting a spraying equipment and surroundings in a paper or board machine, for applying a treatment medium onto a moving surface, comprises a protecting cover forming a single chamber having the spraying equipment located therein and which is open towards the moving surface in connection with an application zone. Two wall elements of the protecting cover extend in the cross-machine direction on either side of the application zone, and define machine-wide gaps with the moving surface. The protecting cover includes a sealing arrangement arranged in connection with the gaps to control and restrict passage of air and contaminants through the gaps; a system for a controlled supply of capture air for capturing contaminants within the space; and an evacuating system for a controlled, continuous evacuation of the capture air with contaminants from the chamber. An associated method of using such a device is also provided.
