Here, There, Everywhere: Pall in the Airport

Whether you’re traveling by air for business or pleasure, you may not realize it, but you’re surrounded by Pall technology. Continuing our popular series, here are a few examples of how Pall contributions are evident throughout your airport experience and when you’re airborne.

Your mobile boarding pass: Forget those pesky paper boarding passes. Millions of travelers use the mobile variety to save time and boost convenience while boarding their planes. Of course, they wouldn’t be possible without smartphones, which are powered by microchips that rely on Pall filtration technology during production.

Flight displays and wayfinding signage: Microchips produced with Pall filtration are used in airport flight displays and digital signage, enabling seamless navigation through the terminals-especially vital for first-time travelers and tight connection scenarios.

While you wait: Many travelers relax before a flight with a meal, drink or snack at airport restaurants and concession stands.

• Your glass of wine: It may have been may be filtered through Pall’s Oenoflow™ PRO crossflow filter systems, our sheet-based SUPRA products or cartridge solutions.
• That cold beer: Raise your glass to Pall solutions, which remove contaminants like particles, colloids, bacteria and yeast—things that can ruin a beer’s taste, flavor and freshness.
• A refreshing soda: Pall products, like the Ultipleat® High Flow filters, may have been used for water and concentrate filtration to ensure the product consistency you’ve come to expect.
• A plant-based meal: That meatless burger may have been produced with the help of Pall filtration, which helps manufacturers extract and clarify plant proteins to produce the highest quality product.

After takeoff:

• Clean cabin air: Pall filters are installed in thousands of airplanes, helping to purify cabin air and reduce the spread of germs and viruses in the closed environment.
• Contamination-free aircraft controls: The hydraulic systems that power flight control surfaces, flaps and slats, and many other airplane components, must be free from dirt, water and air to work properly and help keep these systems working reliably.
• High-purity fuel: Airplane engines use specifically developed, high-performance aviation jet fuel with high energy content. Pall filters are engineered to help keep the fuel to high purity standards by curbing contamination that can inhibit a system's primary functions. To lower greenhouse gas (GHG) emissions from flight, Pall also plays a dual role in supporting the shift to sustainable aviation fuels.

Back on the ground:

• Portable oil purifiers that connect directly to aircraft hydraulic systems: Aircraft hydraulic fluids are susceptible to contamination by water, solid particles, chlorinated solvents and air. With the Pall HSPA purifier, contamination can be practically eliminated within a few hours. It significantly reduces the cost of storing and replacing hydraulic fluid and lessens the impact of waste on the environment.
• Ground vehicles: More and more airports are acquiring zero-emission airport vehicles, including electric shuttle buses. Pall solutions are used during EV battery production to ensure the highest cleanliness of battery components and electrolyte fluids.

AI for the future: As artificial intelligence continues to gain traction, it will play a bigger role in your airport experience—forecasting passenger movement, crowd flow, optimizing security and estimating wait time. Pall MicroE solutions are behind today’s latest chips that are powering AI and Generative AI with large language models by helping to eliminate defects due to metals, particles and organics that can cause premature chip/device failure.
