Navigating Health and Comfort in Airports

In the expansive world of modern travel, airports serve as dynamic hubs connecting people across the globe. However, amid the seamless connectivity and operational efficiency, there exists a nuanced concern—the potential health implications associated with prolonged stays in these bustling environments. From temporary discomforts to potential long-term health risks, both passengers and airport employees may encounter various challenges unique to airport spaces.  

Although the COVID-19 pandemic brought concerns about the impact of the built environment on health out of the proverbial “back room,” experts have been mulling over solutions to these problems for decades. Airports are of particularly high concern as they act as something of a mini city. Jet fuel, exhaust, and other chemicals have a large environmental impact on the outdoor air quality, while carbon dioxide and volatile organic compounds (VOCs), like formaldehyde, can greatly impact the health and indoor air quality (IAQ) of airport occupants.  Continue reading “Navigating Health and Comfort in Airports”

Semiconductor Tool Parameter Monitoring Solutions

A semiconductor transistor is a part with specific electronic properties that allow it to serve as a component in microchips and modern electronics like phones, laptops, and more. As these components are small and require precise manufacturing methods, there are facilities dedicated to their manufacture.

These facilities consist of several levels including air handlers and scrubbers for exhaust, HEPA room, fab cleanroom, and subfab areas. The control of pressure, flow, and temperature within the facility is essential.

Semiconductor process tools are used for the production of microchips and other microelectronic components. These process tools are highly engineered and have a multitude of applications such as pneumatics, electrical, electronics, fume exhaust, chemical & gas distribution, radio frequency (RF) generation, and ultra-high vacuum. Dwyer products help to ensure that process tools are being monitored and controlled to the system owner’s designated parameters.  Continue reading “Semiconductor Tool Parameter Monitoring Solutions”

A semiconductor transistor is a part with specific electronic properties that allow it to serve as a component in microchips and modern electronics like phones, laptops, and more. As these components are small and require precise manufacturing methods, there are facilities dedicated to their manufacture.

These facilities consist of several levels including air handlers and scrubbers for exhaust, HEPA room, fab cleanroom, and subfab areas. The control of differential pressure within the facility is essential for the safety of both equipment and personnel.

The HEPA/ULPA rooms are found in the space above a semiconductor cleanroom. This area has filtration equipment that removes particulates from the outside environment. A HEPA (high efficiency particulate air) filter and/or an ULPA (ultra low particulate air) filter is used to trap small contaminants and prevent them from entering the fab cleanroom area. The fab cleanroom has to be free of particulates, as it is where semiconductor devices such as microscopic transistors are manufactured. Something as small as a molecule from a fragrance can destroy one of these transistors, making proper filtration an essential part of the semiconductor fabrication process.  Continue reading “Monitoring Solutions for Semiconductor HEPA/ULPA Rooms”
