RKT control flaps

A control flap is a device used in air-conditioning systems to control air flow. They serve adjustment of volume and direction of air flow in various portions of the system. The flaps may be controlled manually or automatically using servo actuators. Opening or closing of the flaps may be controlled according to various requirements. The air-conditioning control flaps are used in the air-conditioning systems of buildings, in air-conditioning units, canals and duct works. Their use may achieve optimum air distribution and efficient operation of the system as a whole.
