Moisture-Eliminating Breather Vents
Keep moisture, dirt, and debris from entering your oil reservoirs. The silica gel inside these breather vents absorbs moisture from the air, preventing rust from forming inside your tanks. The gel changes from blue to pink as it becomes saturated, letting you know it needs to be replaced. A second filter blocks dust and other particles from getting inside. These breather vents allow air to flow in and out of your lubrication system, keeping excess vacuum or pressure from building up in cylinders, gear boxes, and tanks.
Breather vents with a plastic body are clear, so a quick glance will tell you if the gel is saturated. Unlike steel versions, which can be rebuilt, the entire unit must be replaced when fresh gel is needed. For washdown environments, select breather vents with check valves. These valves allow air to flow in and out, but close when liquids try to enter.
For an extended service life, use breather vents with a steel body. They are stronger than breather vents with plastic bodies and hold up better when exposed to chemicals. A window lets you check the color of the gel. No need to replace the entire unit when the gel is saturated—use rebuild kits to add fresh gel and to replace the window, filters, and gaskets.

Disposable Desiccant Compressed Air Dryer/Filters for Oil and Particle Removal

Use these dryer/filters to protect air-powered tools from water, oil, oil vapor, and particles, then throw them away when you're done. They have a polyurethane housing that has excellent resistance to synthetic compressor lubricants, solvents, acids, and chemicals. The bowl is clear so you can monitor the desiccant. When it becomes saturated, it changes color to indicate the dryer/filter should be replaced. Install in your air line just before the tool you wish to protect.

Desiccant Compressed Air Dryer/Filters for Oil and Particle Removal



These dryer/filters have a clay desiccant that removes moisture, oil, and particles, so there’s no need to install a separate filter and dryer. Once aftercoolers and separators have removed the bulk of the water, they remove any remaining moisture in your air line. Dryer/filters have a clear bowl or sight glass that allow you to see inside to monitor the contents. When the desiccant becomes saturated, it changes color to indicate that it should be replaced.
Dryer/filters with an aluminum bowl stand up to synthetic compressor lubricants and solvents better than dyers with an acrylic plastic bowl can.

Easy-View Desiccant Compressed Air Dryer/Filters for Oil and Particle Removal



With a clear polycarbonate bowl that’s visible from all angles and silica gel desiccant that changes from blue to pink, it’s easy to see when it’s time to change the cartridge on these dryer/filters and dryer/filter/regulators. In addition to water, they remove compressor oil and particles, preventing damage to air-powered tools and equipment. Unlike some desiccant dryers, they don't require a filter to protect the desiccant. Both the dryer and filter are in the same cartridge, saving space and reducing downtime when they need to be changed. Install them after aftercoolers and separators, which remove the bulk of the moisture.
Dryer/filters and dryer/filter/regulators with a shut-off valve can stop the flow of air when the units are not in use to extend the life of the desiccant.
Dryer/filter/regulators have a regulator to monitor and adjust the flow of air.

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 at its reactivation temperature until it returns to its dry desiccant color. Install after an oil filter to protect the desiccant.
Dryers with a clear bowl and dryers with a sight glass allow you to see inside to monitor contents.
Dryers with a metal bowl are more durable and stand up to vapor better than dryers with a plastic bowl.
