    摘要: An air current controlling device for a clean room having a high efficiency particle filter, a housing cap for the filter, and an air current directional controller provided between the filter and the housing cap. The controller has a shaft extending therefrom, which extends through a central opening in the bottom of the housing cap. The controller includes a plurality of extendable and retractable blades, each being connected to a square plate that is in turn connected to the shaft. A clean room having the above air current controlling device installed in each air inlet is capable of widely distributing the clean air in the clean room. The wide air distribution reduces the temperature difference in the clean room, while optimizing the relative humidity and thereby reducing the electrostatic level of the clean room.

    摘要: A particle counter for counting a number of particles in an air sample includes a sampling probe connected to a counter body with an intake section of the sampling probe having an adjustable area. The intake section is constructed of a plurality of telescopically interconnected shaped pieces that slide within one another to permit lengthening and shortening. The degree of lengthening or shortening determines the adjustable area of the sampling probe, which corresponds to an air speed of the air sample to provide precise particle measurements.
