Shielded Equipment-Cooling Fan Guards
Made of conductive metal, these guards cover fans to block EMI (electromagnetic interference) and RFI (radio frequency interference). The screen also helps keep large debris out of your enclosure and protects fingers from spinning fans.
Mesh fan guards work for general purpose shielding.
Honeycomb fan guards shield sensitive parts, such as precision measuring equipment. They have high interference reduction at frequency, also known as attenuation, so they block most interference. The beryllium copper gasket seals gaps between the fan guard and your enclosure for additional protection. Do not use in direct contact with acetylene.

Fan Shroud Air Filters
These filters fit over fans with round guards to trap dust and debris, keeping contaminants out of the air and off of your fan. An elastic band holds them securely in place.
Front-mount filters fit over the entire front of fans, blocking dust that has entered the fan from blowing back out into the air. Back-mount filters have a center hole, and secure around a fan’s motor housing with a hook and loop closure. They filter air as it enters the fan, protecting the blades and bearings from wear and damage while also reducing the amount of dust the fan will blow out.
Polyester filters are disposable—replace them when they’re dirty. Polypropylene filters have an electrostatic charge that attracts particles, and can be washed and reused.
Dirt and dust stands out on white filters, so it’s easy to see when they need to be cleaned or replaced.

EMI/RFI-Shielding 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.
Also known as attenuation, interference reduction at frequency measures how much interference is blocked. These vents have high attenuation and work for most applications.
