   Light from the lamp, usually a Xenon arc lamp similar to those used in film projectors with a power between 1 kW and 7 kW, is split by colored filters into red, green and blue beams which are directed at the appropriate DMD. The 'forward' reflected beam from the three DMDs is then re-combined and focused by the lens onto the cinema screen.

   Window fans are designed to fit into open windows, and often have expandable side panels to cover the entire window opening. Most units have either one large fan, or two small fans mounted side by side. [1] Most window fans have two or three speeds, and some are electrically reversible so that the user can switch between intake and exhaust modes.

7. Variable air volume - Wikipedia

   en.wikipedia.org/wiki/Variable_air_volume

   The fan maintains a constant static pressure in the discharge duct regardless of the position of the VAV box. Therefore, as the box closes, the fan slows down or restricts the amount of air going into the supply duct. As the box opens, the fan speeds up and allows more air flow into the duct, maintaining a constant static pressure. [11]

9. Vacuum cleaner - Wikipedia

   en.wikipedia.org/wiki/Vacuum_cleaner

   Because of their large-bladed fans, and comparatively short airpaths, direct-fan cleaners create a very efficient airflow from a low amount of power, and make effective carpet cleaners. Their "above-floor" cleaning power is less efficient, since the airflow is lost when it passes through a long hose, and the fan has been optimized for airflow ...
