Fan protective guards are designed to prevent people or things from getting caught in industrial fans' spinning blades. They also help reduce noise and improve airflow. Several types of metal wire form fan guards in a variety of shapes and layouts. They can be mounted through a hole secured with a screw or bolt or snapped on directly. A guard can also be a complete assembly that includes filter media to reduce the passage of dust particles into enclosures.
A fan guard is usually made of metal, but some are also made of plastic or other materials. They are typically installed on top of a fan and can be found in residential, commercial, and industrial settings. They can be used in any type of fan, including ones in electronics, motorized equipment, and ventilation systems. They are commonly used in manufacturing or processing plants to prevent objects from falling into the fan and damaging it.
The primary function of a fan guard is to provide a physical barrier around the moving blades to protect people and prevent accidental injury. They also can maximize fan performance, increase energy efficiency, and reduce noise. A fan guard may be used in any type of environment, but they are most often seen in industrial environments where there are a lot of fans. These include duct fans, exhaust fans, cooling towers, refrigeration unit fans, and electronic devices with fans.
One of the most common types of fan guards is a wire mesh guard that is welded to the blades. This can be made of a variety of materials, but the most common is stainless steel. Welded stainless steel wire mesh is resistant to corrosion and can withstand a variety of temperatures and conditions. It can be finished with a variety of coatings and finishes, depending on the needs of the application.
Other types of fan guards are metal or plastic covers that fit over the blades. These are generally easier to install, but they do not block the airflow as well as a welded wire mesh guard. They can be installed with screws or velcro, and they are typically attached to the fan frame. Some have built-in hinges that allow them to fold up and down when not in use.
Whether you're looking for a metal wire or plastic fan guard, it is important to check the openings regularly for compliance with ANSI standards and safety codes. This is a great tool to have on hand for checking the safety of any fan guard, as it will help ensure that the blade openings are not too big or too small. The size of the openings is critical to ensuring that workers are not exposed to hazardous blades. This is especially important if you work in an environment where the fan guards are positioned close to employees.
