Electrical Enclosure Vents


Style A	Style B	Style C	Style D

Attach these vents to the top or side of sealed enclosures, so air can flow through to equalize internal and external temperature and pressure.

Style A

Style A vents have an angled outlet, which helps keep rain, snow, and debris from entering the vent and the enclosure.

EMI/RFI Shielding Electrical Enclosure Vents

These conductive aluminum screens block electromagnetic interference (EMI) and radio frequency interference (RFI) to prevent electrical problems such as radio static and faulty signals. Made of mesh, they let air flow through, so the pressure in your enclosure stays constant as temperatures fluctuate.

Screw through the vent frame to mount on the surface of your enclosure. A shielded foam gasket fills the gap between the enclosure and the vent.

Interference Reduction @ Frequency—Also known as attenuation, interference reduction at frequency measures how much interference is blocked. These vents have high attenuation and work for most applications.

Floor Sink Liners

Place these liners on top of an old or damaged floor sink. Made of 304 stainless steel, they’re durable and resist corrosion from liquids draining through. Their smooth surface also makes them easy to clean. A rubber gasket seals these liners to the existing drain and secures it in place. The grate prevents large debris from entering the liner. For another level of protection, a dome strainer sits at the bottom of these liners to stop small debris from entering the plumbing system.

Self-Draining Breather Vents

Minimize moisture buildup in enclosures. Also known as drain plugs, these breather vents have a small outlet that allows condensation to drain. They have a silicone O-ring above the threads for a tight seal. Install them at the lowest point of the enclosure. Breather vents meet IP66 for protection in washdown environments. Use them to prevent excess vacuum and pressure in cylinders, gear boxes, and tanks and to block debris from entering equipment.

Moisture Absorbing 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.

Steel Body—NPT Male


	Repair Kits

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.

Repair Kits—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.
