Customize your air preparation system with dryers, filters, and other purifying parts.
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.

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.

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.
