AirTAC Compressed Air Preparation Units on Applied Automation

General Guide & Overview

Compressed air is a widely used form of energy in various industries, powering pneumatic systems and equipment. However, the air leaving the compressor is often not suitable for direct use due to impurities and incorrect pressure levels. That's where air preparation units, also known as FRL units (Filter, Regulator, Lubricator), play a crucial role.

Air preparation units are designed to condition the compressed air, ensuring optimal performance and efficiency. The FRL unit consists of three separate units that carry out different phases of conditioning: filtration, regulation, and lubrication.

Filtration is the first step, where contaminants such as dust, water, and oil are removed from the compressed air. This ensures that downstream equipment remains protected and operates at its best. Regulation is the second phase, controlling the pressure of the compressed air in the system to match the requirements of the application. Lastly, lubrication introduces controlled amounts of oil into the flow of compressed air, reducing friction and increasing the lifespan of air-driven equipment.

Proper selection of the filter size, pressure rating, port size, and lubricator type is essential to meet the specific requirements of each application. By investing in high-quality compressed air preparation units, you can ensure the longevity of your pneumatic equipment and optimize its performance.

So, whether you are in manufacturing, automotive, or any other industry that relies on compressed air, understanding the importance of air preparation units is vital for efficient and reliable operation.

Importance of Air Preparation in Pneumatic Systems

Air preparation plays a vital role in pneumatic systems, ensuring the cleanliness, pressure, and lubrication of compressed air. In order to maintain optimal performance and reliability, it is crucial to address the presence of contaminants such as particles, water, and oil that can impair the operation of pneumatic components. Proper filtration is necessary to remove dirt, dust, and other particles from the compressed air and minimize the risk of damage to downstream equipment.

Moisture and oil, which can negatively impact the performance of pneumatic systems, are effectively eliminated through the use of coalescing filters. The level of air purity required will vary depending on the specific application, and different industry segments may have additional requirements to ensure the proper functioning of their equipment. Therefore, it is essential to select and implement the appropriate air preparation measures.

In addition to addressing contaminants, the flow rate of compressed air must be adequate to achieve the desired cylinder piston travel speeds. Furthermore, the operating pressure of the system needs to be carefully matched to the requirements of the application for optimal performance. By paying attention to these factors and implementing proper air preparation techniques, businesses can improve the process reliability, machine availability, and service life of their pneumatic components.

Tips for Designing and Specifying Air Preparation Systems

When designing or specifying air preparation subsystems, engineers need to consider several key factors to ensure optimal performance and minimize maintenance costs. One crucial aspect is properly matching the port sizes and operating pressure ranges of pneumatic components. This ensures efficient operation and prevents issues such as pressure drops or excessive pressure that can lead to equipment damage or downtime.

Another important consideration is the inclusion of disconnect components, such as manual shut-off relief valves and isolation/lockout valves. These components provide a means to isolate downstream equipment from the compressed air source, allowing for safe maintenance procedures and preventing inadvertent re-energization. This not only enhances safety but also reduces the risk of equipment breakdown and associated maintenance costs.

Air filtration is a critical aspect of air preparation systems, as it eliminates contaminants that could affect the performance and lifespan of pneumatic equipment. Various passive filters, such as centrifugal and coalescing filters, effectively remove particles, water, and oil from the compressed air, ensuring clean and reliable operation. Additionally, implementing appropriate drain systems, such as manual, semi-automatic, or automatic drains, helps to remove accumulated moisture from the filter bowl, further enhancing the efficiency and longevity of the system.

Finally, maintaining proper downstream air pressure is of utmost importance. This can be achieved through the installation of air pressure regulators. These regulators ensure that the compressed air delivered to the equipment operates at the correct pressure, preventing potential damage or inefficiencies caused by excessive or insufficient pressure. By following these tips and incorporating the right components, engineers can design and specify air preparation systems that optimize the performance and longevity of pneumatic equipment, ultimately reducing maintenance costs and downtime.
