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.

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-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.

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.

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.

Desiccant Compressed Air Dryers


Style D	Style E

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.

Style D

The desiccant in Styles D and E comes in a sleeve, so they're easier to maintain than dryers with loose beads. Reheat the entire sleeve to reuse the desiccant. To make sure they drain properly, install these dryers on vertical segments of your air line.

Clear Bowl—Dryers with a clear bowl or a sight glass let you keep an eye on the contents inside.

High-Flow Compressed Air Separators

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.

Desiccant Compressed Air Dryers with Filters for Oil and Particle Removal

Style E

Prevent damage to air-powered tools and equipment—these dryers remove water, compressor oil, and particles from your air supply. The dryer and oil filter share the same cartridge to save space and reduce downtime when changing them. No need to mess with desiccant beads. Install them after separators and aftercoolers, which remove the bulk of the moisture.

When selecting a dryer, keep in mind that the larger the desiccant capacity, the longer they last between cartridge changes.

Clear Bowl—Dryers with a clear bowl are visible from all angles. They have a silica gel desiccant that changes from blue to pink, making it easy to know when to replace the cartridge. Disassembly is required to access the desiccant.

Style E—Style E filter fine particles in the same cartridge as the dryer and oil filter. Install them vertically in your compressed air line so any water vapor collecting drains properly.

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 female dryers make replacing desiccant easy—simply remove the bowl. When you replace the desiccant, service or replace the filter element to extend its life.

Compressed Air Separators for Oil Removal

Opaque Bowl

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.
