Desiccant Compressed Air Dryers

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

High-Pressure Desiccant Compressed Air Dryers

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.
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.
Norgren Modular Desiccant Compressed Air Dryers

For use with Norgren modular compressed air systems, once aftercoolers and separators have removed the bulk of the water, use one of these desiccant-filled dryers to remove any remaining moisture in your air line. Install after an oil filter to protect the desiccant. They have a clear bowl so you can see inside to monitor contents. To reuse saturated desiccant, heat it at its reactivation temperature until it returns to its dry color.
Use a joiner clamp (sold separately) to connect your dryer to another Norgren modular component.
End block sets (sold separately) allow you to swap out filter/regulator/lubricator components without unthreading your air line connections. The blocks remain connected to your pipe while you replace components between them.

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


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 A are compact and quiet, making them ideal for point-of-use drying on shop floors. A display shows real-time drying data and alerts you for maintenance.
Style B have multiple inlets and outlets for mounting versatility—install them horizontally or vertically. They’re often used in industrial automation and manufacturing. Replacement filter elements help remove oil and particles and extend equipment life. Replacement service kits include desiccant cartridges, O-rings, and washers.

Compressed Air Separators
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.
Separators with a sight glass allow you to see inside the bowl to monitor its contents.

Compressed Air Separators for Oil Removal
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.
Separators with an aluminum bowl are stronger than those with a polycarbonate plastic bowl—they won’t crack or shatter if dropped.
