Inline Filters - Air Logic

Inline filters protect systems and equipment from damage by removing harmful particles, contaminants, and debris from the media that passes through them. Ideal for applications that require a compact filter size and direct flow capabilities, these filters maintain the purity of liquid and have varying filtration levels for application-specific needs.

With competitive price and timely delivery, NAILI sincerely hope to be your supplier and partner.

Inline Air Filters

No matter the application, clean air is important to maintain safe and efficient processes. Though inline air filters are available in sizes ranging from miniature to extra large, at Air Logic, we specialize in miniature and small filters. As contaminants like pollen, dust, machining chips, and Teflon tape enter the system, they are captured by the inline filter, and clean air can be used in the system.

Our filters are suitable for use within devices or in single-use applications, particularly those requiring direct flow through the filter or compact filter sizes. For critical device components, inline filters can be used in conjunction with larger filters, providing finer debris filtration to protect important components.

Benefits of an Inline Air Filter

Air Logic inline filters offer safety, efficiency, and convenience to applications in a range of industries. Our filters don’t require mounting, allowing for quick, simple installation.

They also provide the following additional benefits:

  • Improved product quality: For manufacturing processes that require consistently clean air, inline air filters make this possible. Specifically, these filters protect against certain fine particles and debris that might otherwise damage systems such as semiconductors or contaminate medical devices or life science systems.
  • Removal of airborne leftovers: Certain airborne leftovers produced during manufacturing processes may cause harm to critical system components, processes, employees, and operations. Inline air filters can remove these leftovers to create a safer environment, a more reliable device, and reduce premature product failure.
  • Protection for tools: Dirty air has the potential to cause damage to critical equipment, resulting in delayed production times and customer dissatisfaction. Air filters help maintain compressed air tools, ensuring they stay in good working condition by protecting them from potential contaminants that could otherwise cause damage to tools.

Complete Guide to Inline Filtration for Compressed Air

Compressed air is the lifeblood of many industrial processes, powering everything from paint guns to pneumatic drills. This is a widely used source of power in different sectors including manufacturing and healthcare. But compressed air isn’t always pristine. It can contain contaminants like dust, moisture, and oil aerosols, which can wreak havoc on your equipment and impact the quality of your end product. Here’s where compressed air filters come in.

What is a Compressed Air Filter and Why Do You Need One?

A compressed air filter is a device installed directly into your compressed air system’s pipelines. As the name suggests, it works “inline” to remove impurities before the air reaches its point of use.  These contaminants can originate from the ambient air or even from the compressor itself.  You can ensure clean, dry air by installing an air filter that protects your equipment, improves product quality, and extends the lifespan of your entire compressed air system.

Types of Compressed Air Filters

There are different types of air filters, each designed to target specific contaminants. Choosing the right one depends on the needs of your application. Here’s a breakdown of the most common types:

Dry Particulate Filters: These filters, often featuring a pleated filter cartridge,  remove dry particles like dust, rust, and pipe scale. They’re ideal for applications where moisture and oil aren’t a concern, such as powering pneumatic tools.

Coalescing Filters:  These compressed air filters address both particulate and aerosols. They use a pleated filter cartridge with a special media that allows air to pass through while trapping liquid droplets like water and oil mist.  The coalescing process merges these tiny droplets into larger ones that fall to the bottom of the filter housing, where they can be drained automatically or manually.  Coalescing filters are a must-have if your compressed air system uses a lubricated compressor.

Adsorption (Activated Carbon) Filters:  These filters target gaseous contaminants like oil vapors and odors. They use activated carbon, a material with a vast surface area that attracts and traps these unwanted molecules.  Adsorption filters are often used in conjunction with other filtration stages to achieve extremely high air quality for sensitive applications in industries like food and beverage, electronics, and pharmaceuticals.

The Importance of Inline Filtration

Inline filtration for compressed air is crucial because even small amounts of contaminants can cause significant damage to pneumatic equipment and compromise product quality. For instance, oil and water contamination can lead to malfunctioning valves, clogged orifices, and reduced efficiency in air-powered tools and machinery. Moreover, in industries such as food and beverage, pharmaceuticals, and electronics manufacturing, maintaining clean compressed air is essential to prevent product contamination and ensure compliance with industry regulations.

Benefits of Pleated Filter Cartridges

Pleated filter cartridges are a popular choice for inline filtration in compressed air systems due to their high efficiency and long service life. These cartridges consist of a pleated filter media enclosed within a cylindrical or rectangular housing, providing a large surface area for trapping contaminants while maintaining low-pressure drop. The pleated design allows for maximum filtration capacity and minimal maintenance, making them ideal for demanding applications.

Choosing the Right Compressed Air Filter:

Contaminants: Identify the specific contaminants you need to remove from your compressed air.

Air Quality Requirements: Different applications have varying air quality demands.  For instance, painting requires cleaner air than operating a drill.  Determine the required micron rating of your filter, which indicates the smallest particle size it can remove.

Flow Rate: Choose a filter with a capacity that can handle the airflow of your compressed air system.

Pressure Rating: Ensure the filter’s pressure rating is compatible with your system’s operating pressure.

Conclusion

Compressed air filters play a critical role in maintaining the quality and efficiency of pneumatic systems across various industries. By removing contaminants such as oil, water, and particulates, inline filtration ensures the smooth operation of air-powered equipment. Pleated filter cartridges offer a reliable and cost-effective solution for achieving clean compressed air and should be chosen based on the specific requirements of your application.
