    Once aftercoolers and separators have removed the bulk of the water, use these dryers to remove any remaining moisture in your air line. To reuse saturated desiccant, heat it in an oven at its reactivation temperature—you'll know it's dry when the color changes. Install these dryers after an oil filter to protect the desiccant.

    Aluminum Bowl and Steel Bowl— Dryers with a metal bowl are more durable than those with a plastic bowl, and they hold up to vapor better.
    Opaque Bowl with Sight Glass—Dryers with a clear bowl or a sight glass let you keep an eye on the contents inside.

    High-Capacity Refrigerant-Cooled Compressed Air Dryers

    Noncycling

    Air Dryers

    Remove bulk water vapor from your compressed air line by refrigerating the air. These dryers have a timer-activated drain valve that opens automatically to discharge condensate. Install them in your air line after the compressor and separator.
    Noncycling—Noncycling dryers run continuously to dry compressed air, so they’re best for applications with a constant need for dry air.

    High-Capacity Refrigerant-Cooled Compressed Air Dryers with Filters for Particle Removal

    Image of Product. Front orientation. Compressed Air Dryers. High-Capacity Refrigerant-Cooled Compressed Air Dryers with Filters for Particle Removal.
    These all-in-one dryers with filters eliminate the need for individual dryers and filters. They cool air through refrigeration to condense water vapor for removal. Because they are noncycling and run continuously, they are best for applications that need constant dry air. A float-operated drain valve opens automatically when the bowl begins to fill. After water removal, a heat exchanger raises the outlet air temperature to prevent condensation on downstream piping. The built-in display lets you monitor and adjust the dew point of the compressed air. Be sure to install in your air line after the compressor and separator.

    Chemical-Resistant Desiccant Compressed Air Dryers with Filters for Oil and Particle Removal

    With a polyurethane bowl and housing, these dryers resist synthetic compressor lubricants, solvents, acids, and other chemicals in your compressed air line. They have a clear bowl so you can monitor contents and the desiccant, which changes color when it needs to be replaced. These dryers use clay desiccant to remove moisture, oil, and particles—no need for a separate filter and dryer. Place them down the line from aftercoolers and separators, which remove most of the water first.

    NPT male dryers are installed inline. To replace the desiccant, remove the entire unit from the line.
