Embodiment Construction

[0030] A few preferred embodiments of the invention have been described for illustrative purposes, it being understood that the invention may be embodied in other ways not specifically shown in the drawings.

[0031] first go to figure 1, which shows a schematic diagram of an exemplary facility 100 having one or more clean rooms 102 therein. Clean room 102 is adjacent to space 104 and outside atmosphere 106 . Adjacent space 104 may be any one or more rooms within the same facility 100 in which clean room 102 is located and adjacent to clean room 102, such as, for example, a separate fabrication room, another clean room, a potting and packaging room ( finish and fill room), research lab or office. The clean room 102 and the adjacent space 104 are separated by a partition such as a wall.

[0032] The clean room 102 in the exemplary facility 100 can be maintained at an air pressure P higher than that of the adjacent space 104. 2 low air pressure P 1 , and the air pressure P ...

Abstract

A sampling system for quantifying the amount of contaminants in a controlled environment within a facility, the controller having a plurality of ports, each port having a timer circuit, a flow rate circuit, a flow switch, and a vacuum tube, wherein the flow rate circuit controls the flow switch and maintains a fluid flow through the vacuum tube at about 1 cfm. The system also includes a plurality of air sampling device located within the controlled environment, each connected to one of the plurality of ports by way of the vacuum tube. A touchpad input / output device is connected to a base station, wherein the base station comprises a communications device for wirelessly sending a start and stop signal from the touchpad to the controller.

Description

technical field [0001] The present invention relates to devices and methods for collecting air samples in indoor ring mirrors. In particular, the present invention relates to apparatus and methods for collecting, processing and analyzing air samples in a clean room, electrically and automatically controlling sampling equipment and calibrating said sampling equipment. Background technique [0002] Clean rooms established in manufacturing, research, and other facilities are typically divided into two categories based on the static air pressure in the room, relative to atmospheric pressure and / or the air pressure in the space adjacent to the clean room. A positive air pressure chamber is maintained at an absolute air pressure greater than atmospheric pressure, greater than the air pressure in the space adjacent to the clean room, or both. Positive air pressure in such chambers is provided by pumping filtered and / or conditioned air into the chamber and controlling the flow of a...
