Shop Pneumatic (Air) Filters

Pneumatic (Air) Filters are essential components in compressed air systems, designed to improve air quality by removing contaminants before they reach equipment or products. We offer three types of filters based on the level of air purity required: general purpose, oil removal, and oil vapor removal. General purpose filters are ideal for removing liquid water, dust, and dirt particles from air lines, making them the most commonly used filter type. Coalescing filters are designed to remove oil droplets from air lines and are commonly used in applications where oil contamination could affect product quality, such as paper manufacturing or food processing. Oil vapor filters are used when the highest air quality is needed, ensuring no odor or oil vapor remains, and should always be used after an oil removal filter. Pneumatic filters are available in modular and inline styles, as well as in specialty materials like stainless steel, to suit different system requirements.


Ideal for removing liquid water, dust, and dirt particles from your air lines. This is the most common filter used.


  • Filtration at 5 or 40 microns

  • Cost effective

  • Less frequent element changes

  • Mechanical Indicator available


Ideal for removing oil droplets from air lines. Used in applications where oil could contaminate a product, like paper manufacturing and food processes. 

  • Design forces air turbulence which coalesces oil droplets together to fall to bottom
  • More expensive than General Purpose Filters

  • Filtration down to 0.01 micron

  • Mechanical Indicator available


Only required when highest air quality and no odor is allowed in a pneumatic application. You MUST use an oil removal element inline before a vapor element.

  • Activated carbon filter element

  • Most expensive filter style

  • Fixed length service life based on operating hours.

  • Element changes color when saturated with oil
