Abstract
A fluid diffuser and a method for diffusing fluid are provided. In one preferred embodiment, the diffuser comprises a frame adapted to be connected to the end of fluid supply duct. Mounted within the frame is a pore-containing web. The web redirects fluid passing through the pores by changing the direction of the fluid upon exiting the web. Prescribed portions of the web can be blocked to expel fluid preferentially in one direction and expel fluid less in other directions. Other means for controlling the direction and flow of fluid upon exiting the web are provided, including changing the angle of fluid supply to the web, and placing a vane at the entrance to the web.
