Compressed air filters

Process Filters

Process filters are high-performance filtration solutions designed for industries that require ultra-clean, contaminant-free compressed air. These filters play a crucial role in food & beverage, pharmaceuticals, electronics, and medical applications, where even microscopic impurities can compromise product quality, safety, and regulatory compliance. By removing bacteria, oil vapors, fine particulates, and moisture, process filters ensure that compressed air meets the highest purity standards for sensitive operations.

How do line process filters work?

Process filters utilize advanced filtration media to remove ultra-fine contaminants from compressed air, ensuring the highest levels of purity for sensitive applications. As compressed air passes through the filter, multiple filtration mechanisms—such as mechanical separation, adsorption, and coalescence—work together to trap particles, moisture, oil aerosols, and vapors. These filters operate at extremely fine filtration levels (as low as 0.01 microns), effectively eliminating even microscopic impurities that standard line filters cannot capture. By maintaining consistent air purity, process filters help meet strict industry regulations, such as ISO 8573-1, ensuring compliance with food, pharmaceutical, medical, and high-tech manufacturing requirements.

How to choose the right process filter?

Selecting the correct process filter depends on your industry, air quality requirements, and specific contaminants. If your application involves direct contact with food or pharmaceuticals, a sterile filter with bacterial retention capabilities is essential. For removing oil vapors and odors, an activated carbon filter is the best choice. When dealing with moisture-sensitive environments, a membrane dryer filter provides effective dehumidification. It's also critical to consider air purity standards, such as ISO 8573-1 and FDA or GMP regulations, to ensure compliance. Additionally, evaluate your system’s flow rate, pressure rating, and maintenance requirements to select a filter that balances performance, efficiency, and longevity.

Process filters maintenance

To maintain peak efficiency, regular inspection and timely filter replacement are essential. Process filters often have differential pressure indicators, signaling when the filter element is clogged and needs replacement. Sterile filters require periodic steam sterilization or autoclaving to maintain hygiene, while activated carbon filters must be changed once they reach saturation to avoid performance degradation. Following manufacturer recommendations for maintenance schedules ensures consistent air purity, prevents pressure drops, and extends the lifespan of downstream equipment.
