Unlike mesh screens, metal fan guards are not limited to small openings

Electrical Fan Guard protects the spinning blades of cooling fans from accidental contact with objects and fingers. They are constructed from a variety of materials including metal wire or plastic. They come in many different shapes and sizes to accommodate the needs of specific applications. They can also be coated, polished, and anodized in various ways to enhance performance and/or aesthetics. The majority of manufacturers offer custom fan guards and accessories that are designed to meet individual customer requirements.
Unlike mesh screens, metal fan guards are not limited to small openings and can offer more control over airflow. They can promote better heat dissipation and are particularly useful in electronic devices where dust and foreign objects can greatly shorten their lifespan. They can also help to eliminate noise by reducing vibration.
The design of these industrial & office fan guards allows them to fit over existing fans and provide a physical barrier that keeps objects away from the blades. They are often used in conjunction with a fan filter to reduce the passage of dust particles into enclosures, and they can be equipped with safety latches to prevent accidental engagement with rotating fan blades.
Injection molding is a common fabrication technique for producing plastic fan guards, with materials such as polybutylene terephthalate (PBT), acrylonitrile butadiene styrene (ABS), or polycarbonate often used. They can be designed to meet UL94V-0 and other fire resistance standards.
Depending on the application, these flat-type fan guards can be zinc-plated or chrome-plated and powder-coated against corrosion. They are usually used in the manufacture of computer case fans and can be fitted with a clamp or screws to secure them to the fan. They are also ideal for protecting security lights, fluorescent tube lights, and cameras. They can be designed with a wide range of hole sizes to prevent workers' fingers from getting hurt and to improve energy efficiency. They can be supplied in black, nickel chrome, or other colors to match the color of the fan or for aesthetic purposes.
