Compressed Air Filters

Compressed Air Filters

John Henry Foster offers a wide range of compressed air filters designed to remove contaminants such as dust, oil, water, and particulates from the air supply. These filters improve air quality, protect equipment, and enhance system performance. Available filters include coalescing filters (for removing oil and water), particulate filters (for trapping solid particles), and activated carbon filters (for oil vapor and odor removal). With various sizes and filtration levels, JHF can help you select the right filter for your specific application to ensure clean, reliable compressed air for your operations.

Coalescing Filters (For Oil and Water Removal)
Coalescing filters are designed to remove oil aerosols, water droplets, and fine liquid mist from compressed air. As the air passes through the filter media, tiny droplets coalesce into larger ones, which are then drained away. These filters are essential for protecting sensitive equipment and ensuring clean, dry air downstream, particularly in systems that require low oil content.

  • Filtration Rating: Typically 0.01 - 1 micron.
  • Max Pressure: Up to 250 psig (varies by model).
  • Temperature Range: 35°F to 180°F (1.6°C to 82°C).
  • Applications: Pharmaceuticals, food processing, and electronics.
Particulate Filters (For Solid Particles Removal)
Particulate filters target solid contaminants like dust, dirt, rust, and pipe scale that can enter the compressed air system. They use fine filter media to trap these particles before they reach equipment or end-use points. Ideal for pre-filtration or general-purpose protection, particulate filters help extend the life of downstream components, reduce wear, and maintain system efficiency.

  • Filtration Rating: 1 - 40 microns.
  • Max Pressure: 150 psig (varies by model).
  • Temperature Range: 35°F to 180°F (1.6°C to 82°C).
  • Applications: Ideal for protecting pneumatic tools and sensitive equipment from solid contamination.
Activated Carbon Filters (For Oil Vapor and Odor Removal)
Activated carbon filters are used to remove oil vapors, hydrocarbons, and odors from compressed air. These filters rely on a highly porous carbon material that adsorbs gaseous contaminants, making them ideal for applications where air purity and smell control are critical. They are typically used as a final filtration stage after coalescing and particulate filters. 

  • Filtration Rating: Typically 0.003 - 0.01 micron for vapor removal.
  • Max Pressure: 150 psig (varies by model).
  • Temperature Range: 35°F to 180°F (1.6°C to 82°C).
  • Applications: Used in applications requiring clean air for sensitive processes, including food and beverage packaging, electronics, and medical equipment.
