Protect against excess vacuum and pressure in cylinders, gear boxes, enclosures, manifolds, and tanks. You can also use these breather vents to block debris from entering equipment.

Breather vents with splash guard are good for containers that are often filled and drained; they have a guard that prevents oil from splashing out of the vent hole.

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.
