Breather Vents
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.

Washdown Weather-Resistant Breather Vents
These breather vents are rated NEMA 6 to withstand periodic submersion in water. Install them in enclosures to stop the buildup of pressure and vacuum and to prevent debris from entering equipment. Breather vents can be used with enclosures that are rated NEMA 4, 12, and 13 for washdown environments and splashing oil and coolant.
Vents with barbed connections fit unthreaded openings and are held in place by friction.

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.

Hazardous Location Drain Vents
Safe for use around hazardous gasses and dust, these vents maintain steady pressure and prevent moisture buildup from temperature changes inside enclosures. They allow air to flow through the enclosures while protecting the contents from washdowns, dirt, and weather. Install these vents at the lowest point on an enclosure, so moisture can drip out.
Increased-safety drains keep sparks, high temperatures, or current creepage inside an enclosure, so they won’t ignite flammable gasses and dust.
Glass-filled nylon drains are lightweight yet durable. They’re good for most areas.
