A split air conditioner has a cabinet with a fan and evaporator for mounting within a structure. The cabinet includes one or more movable dampers or movable filters positioned in the flow path between the air inlet and the outlet for selectively filtering contaminants from the air to provide a greater or lesser degree of filtration of the air. The movable filters include sliding and/or pivot mounting structure which may accommodate stacking multiple filters with different filtering characteristics. The system may operate in a filtering only mode with no cooling, a cooling only mode with no filtering, or a combination of cooling and selective filtering.

A particle control method configured prevent an extremely small quantity of particles descending on a stream of a laminar flow in a clean zone through which the laminar flow flows (as in a RABS or isolator device) from descending to a specific position or to guide the particles so as to have them descend to a specific position by controlling movement of the particles. [Solution] A particle descent position is separated away from a board surface of the oscillation board by using an acoustic radiation pressure generated by prompting ultrasonic vibration of the oscillation board disposed with a board surface substantially in parallel with a flow direction of the laminar flow. Moreover, by using a node of a standing wave field generated by prompting the ultrasonic vibration of two oscillation boards disposed with the board surfaces faced with each other, the particle is guided to a direction of a node of a standing wave field. Moreover, by using a focal point of the ultrasonic wave generated by prompting the ultrasonic wave of four oscillation boards, that is, two pairs disposed with the board surfaces faced with each other, the particle is guided to the focal point of the ultrasonic wave.
