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.
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.
Desiccant Compressed Air Dryers with Filters for Oil and Particle Removal
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. 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 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.

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 non-cycling 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.

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 feet can be placed on the floor or suspended from piping without support.

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.
