Pneumatic Filters

Pneumatic filters ensure the proper functioning of pneumatic systems by eliminating contaminants such as water and oil vapor from compressed air. Some filters use a 'media' to capture particles while allowing air to pass through, whereas others utilize membranes that permit only air to flow. These filters are commonly paired with pneumatic air lubricators.

Pneumatic filters are essential components that help prevent the failure of pneumatic equipment. The frequency of maintenance depends on the volume of debris filtered. A noticeable pressure drop often indicates that the filter requires cleaning. However, certain parts like the service indicator and the automatic or manual drain should not be serviced.

Pneumatic Resources offers a wide selection of pneumatic equipment, including filtration products designed to remove contaminants. Our inventory includes filters in various configurations, with different filtration sizes, port connections, and drain types (automatic and manual) to suit a range of filtration needs.

What are pneumatic filters used for?

Pneumatic filters are employed across diverse industries and environments such as healthcare, analytical instrumentation, food processing, marine and aviation sectors, manufacturing, and food and beverage packaging. To ensure pneumatic systems operate efficiently, compressed air must be clean and free from water and particulates. Pneumatic filters help by removing contaminants and extending the life of components.

Primary filters

Primary filters safeguard pneumatic equipment from damage caused by contaminants like dirt particles, tiny water droplets, or aerosols. They can filter out particles as small as five micrometers.

Secondary filters

Secondary filters are capable of trapping particles as small as 50 nanometers, effectively removing fumes, odors, moisture, oils, and other extremely fine particles from the air stream.

What types of pneumatic filters are available?

• Pneumatic Water Separators – designed to remove water
• Pneumatic Particulate Filters – capture dirt and particles
• Pneumatic Coalescing Filters – eliminate water, rust, and oil from compressed air
• Absorbing Filters – remove oil from compressed air streams
