Higher pressure air within a cleanroom (compared to the air outside the room) blocks contaminants from entering the cleanroom, as air naturally wants to flow out. Conversely,lower pressure air within a cleanroom can trap contaminants and prevent them from leaving a cleanroom,as the natural flo...

Positive Air Pressure Cleanrooms normally operate in an air pressure range of 0.02 in. to 0.2 in water column (H20). Positive air pressure means the cleanroom or rooms are "pumped up" with more filtered air then the surrounding space outside the cleanroom(s). There are different cascading...
Room pressures Cleanroom air pressure should be higher than that of the ante-room and the surrounding uncontrolled area. The pressure gradient between these zones should be ≥ 15 Pa. Typical values are:Cleanroom: 30 Pa positive pressure Ante-room: 15 Pa positive pressure Suitable manometers ...
An air pressure controlling damper for a clean room includes a frame(20) fixed to a wall of a clean room(100) and having an air path(24), a hollow fixing element(30) fitted in the frame in contact with an inner peripheral surface of the frame, and a blade(40) sliding with respect...
The PMDS4 clean room monitor is designed for positive and negative monitoring of differential air pressure between the inside and outside of a clean room. Due to the construction of the device it is has a very slim profile and only requires a recess or cavity depth of 44mm to be installed...

A qualified clean room environment has specific requirements for not only particle control but also temperature, humidity, pressure, and oxygen levels which are supplied and controlled by other essential systems. It includes air conditioning systems, circulating and cooling water system, vacuum system, ...
In 2018 our former 400m² was expanded by another clean room with around 800m², therefor we now have almost 1300m² total area. The clean rooms are connected by a transition. Thanks to the new space we were able to increase the machine stock to around 40 machines in total.The ...
Objectives: The purpose of this study was to examine clean room(C/R) structure, air conditioning and contamination control systems and to provide basic information for identifying a correlation between the semiconductor work environment and workers` disease. Methods: This study was conducted at 200 ...
