    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.

    Prevent equipment damage caused by moisture. The first step in water removal, these separators remove the water that accumulates as compressed air cools. They have a float-operated drain valve that automatically opens when the bowl begins to fill. Install in your air line after compressors and aftercoolers.
    Sight Glass—Separators with a sight glass allow you to see inside the bowl to monitor its contents.
    Feet—Separators with feet can be placed on the floor or suspended from piping without support.

    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— 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 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.

    Automatic Continuous-Use Desiccant Compressed Air Dryers with Filters for Oil and Particle Removal

    Image of Product. Front orientation. Compressed Air Dryers. Automatic Continuous-Use Desiccant Compressed Air Dryers with Filters for Oil and Particle Removal, Style C.

    Style C

    For an uninterrupted supply of clean, dry compressed air, these dryers have two desiccant towers. While desiccant in one tower absorbs moisture, the desiccant in the other is drying out, then they switch automatically. In addition to water, they also remove compressor oil and particles to extend their life and the components downstream from them. Install them after separators and aftercoolers, which remove the bulk of the moisture.
    Style C—Style C stand up to tough outdoor and harsh conditions. Install them inline along your air line for a straight-through connection. Replacement service kits for Style C (sold separately) include filters, check valves, and purge valves.

    These separators have higher flow rates compared to our other compressed air separators. Prevent equipment damage and wear caused by moisture in your compressed air supply. The first step in water removal, use one of these separators to remove the large amount of water created as compressed air cools. A float-operated drain valve automatically opens when the bowl begins to fill. Install separators in your air line after compressors and aftercoolers.

    Get dry compressed air in high-pressure systems—these dryers have a maximum pressure rating of 300 psi. Once aftercoolers and separators have removed the bulk of the water, they remove any remaining moisture in your air line. Install after an oil filter to protect the desiccant. They have a sight glass so you can see inside the bowl to monitor contents.
    Desiccants—Desiccant (sold separately) is required to remove moisture from air. To reuse saturated desiccant, heat it at its reactivation temperature until it returns to its dry color.

    SMC Modular Compressed Air Separators

    Keep moisture from damaging your equipment. These separators remove the water that accumulates in your line as compressed air cools. They connect to other SMC units of the same series with joiner clamps (sold separately), even if the pipe sizes differ slightly, so you can customize your air preparation system. They have a float-operated drain valve that automatically opens when the bowl begins to fill. Install them in your air line after compressors and aftercoolers.

    In addition to removing large amounts of water, these separators also remove particles and oil droplets. Place them after your compressor and aftercooler, or at the point of use in applications that don't require an aftercooler. They have an automatic drain to discharge the moisture.
    Aluminum Bowl—Separators with an aluminum bowl are stronger than those with a polycarbonate bowl—they won’t crack or shatter if dropped.
