Pneumatic Inline Air Filter for Pressure & Vacuum 4 6 8 10mm OD Tubing | BD-AF Series BODENFLO

The BD-AF Pneumatic Inline Air Filter Series is designed for particle filtration in both positive-pressure and vacuum pneumatic systems. Featuring a 5 μm filtration rating with 95% particle capture efficiency, these inline filters help reduce contamination in air and nitrogen pipelines, protecting pumps, valves, and other pneumatic components.

Available in four tube connection sizes—4 mm, 6 mm, 8 mm, and 10 mm OD—the BD-AF pressure/vacuum filter series supports different pneumatic connection requirements. Each filter features a polycarbonate housing, two connection ports, and an operating pressure range of –100 kPa to +1.0 MPa at 20°C, making it suitable for compatible OEM pump systems and industrial pneumatic equipment.

Pneumatic Inline Air Filter Features

• 5 Micron Filtration: Helps capture particles from air and nitrogen pipelines with a specified 5 μm filtration rating and 95% particle capture efficiency.
• Positive Pressure & Vacuum Compatibility: Designed for both positive-pressure and vacuum pneumatic systems within the specified operating limits.
• Pneumatic Component Protection: Helps reduce contamination entering pumps, valves, and other connected pneumatic components.
• Four Connection Sizes: Available for 4 mm, 6 mm, 8 mm, and 10 mm OD tubing to support different pneumatic system requirements.
• Compact Polycarbonate Housing: Provides a compact filter enclosure for installation in OEM equipment and industrial pneumatic pipelines.
• Inline Connection Design: Two tubing connection ports support integration into pneumatic pipelines.

Size Selection & Installation Guidelines

• Tube Size Selection: Choose the filter model according to the outer diameter of the tubing used in the pneumatic system.
• Tubing Compatibility: Use compatible nylon, soft nylon, or polyurethane tubing.
• Model Selection: Select one of the four available tube connection sizes. Each model has a fixed connection diameter.
• Filter Installation: Install the filter in the appropriate section of the positive-pressure or vacuum pipeline to help protect downstream pneumatic components.
• Connection Security: Ensure both tubing connections are properly seated and sealed to prevent air leakage or pressure loss.
• Installation Space: Confirm the selected filter's external dimensions and available mounting space before installation.

Important Notes

• Operating Pressure: The specified –100 kPa to +1.0 MPa operating range applies at 20°C. Maximum allowable positive pressure decreases as operating temperature increases above 20°C.
• Pressure vs. Temperature: Refer to the maximum operating pressure versus temperature chart in the product specifications when evaluating higher-temperature applications.
• Proof Pressure: The specified 1.5 MPa proof pressure at 20°C is not a continuous operating pressure rating.
• Operating Temperature: Use within the specified 0–60°C temperature range under non-freezing conditions.
• Filtration Rating: The 5 μm filtration rating and 95% particle capture efficiency should be considered when evaluating application-specific filtration requirements.
• Working Fluid: Designed for air and nitrogen. Confirm compatibility before using other gases or fluids.
• Tubing Selection: Ensure the tubing outer diameter matches the selected filter connection size.
• Filter Maintenance: Inspect the filter periodically and replace it when contamination or blockage causes excessive flow restriction or reduced system performance.
• Pump Compatibility: Recommended BODENFLO pump series vary by filter model. Confirm tubing connections and operating conditions before ordering.
