Why air filtration in food production?

Air quality plays an important role in the safe production of food. The ambient air in production halls must meet certain requirements in terms of temperature, humidity and particle concentration. Certain amounts of fresh outside air are needed for comfort and safety in the workplace. It is also essential to prevent the spread of germs during food production. Controlling the particle content in the air minimizes the risk for product contamination.

Individual air filtration: F7 Filter, F9 Filter or HEPA Filter?

Air quality control and monitoring is critical to minimize contamination and contribute to safe food manufacturing. Airborne contaminants are removed from the air by filtration, and the desired filtration efficiency depends on the acceptable contamination risks. Laminar airflow units are used in high-risk zones. Whether F7, F9 or HEPA filters, selecting the best system requires a detailed risk analysis and knowledge of ventilation systems. The design, construction, installation and commissioning also play an important role in the microbiological safety and durability of the products.

What should be taken into account in air filtration in food production?

In some cases, RLT systems provide good growth conditions for microorganisms. Even if fibers become detached from the filter materials, germs have an easy time of it. It is therefore essential to avoid filters themselves becoming a source of contamination. The risk of germs spreading can be reduced by specifically controlling the relative humidity. In addition, inert filter media should be used that do not provide a breeding ground for fungi or bacteria. Proper design and installation of the filter frame is also important. Closed-cell seals remain intact throughout the life of the filter element. Frames should be sealed to prevent air bypass. Filter elements that can withstand mechanical stresses during operation should be used. They must remain airtight and leak-free even in turbulent conditions. Correct installation of the filters is essential in this respect.
