Fan Guard Ohne hersteller FGR-92B — metal 92 mm protective grill for cooling fans

Protective fan guard Ohne hersteller FGR-92B is a metal 92 mm protective grill designed to fit standard axial cooling fans. It offers a compact and durable barrier that covers fan blades to reduce the risk of accidental contact, protect the fan from foreign objects, and help maintain airflow integrity in small cooling assemblies. The grill is suitable for installations in PC cases, power supplies, ventilation units and other equipment where a 92 mm guard is required.

Advantages

The metal construction provides mechanical strength and resistance to deformation while maintaining low profile dimensions. The guard's geometry allows unhindered airflow with minimal additional turbulence, preserving cooling performance. As a simple, passive safety component, it reduces the chance of damage to fan blades and prevents fingers or tools from reaching the rotating impeller during maintenance.

Suitable for

• 92 mm axial cooling fans in desktop PC cases
• Internal fans in power supplies and small ventilation modules
• Cooling assemblies in consumer electronics and small industrial equipment
• Enclosures where finger protection and foreign object prevention are required

Key specifications

• Size: compatible with 92 mm axial fan mounting
• Material: metal grill for mechanical durability
• Finish: protective coating to resist corrosion and wear
• Mounting: standard screw-mount pattern for 92 mm fans
• Profile: low-profile design to minimize obstruction of airflow

How to use

Position the fan guard over the fan so that the mounting holes align with the fan or chassis screw points. Secure the guard using appropriate screws of the correct length to avoid contacting the fan blades or motor housing. Verify that the guard is firmly attached and that the fan spins freely without contact. For maintenance, power down the device, disconnect from mains or power source, and remove the guard if necessary following the same mounting steps in reverse.

Recommendations

Choose screws that match the thickness of the guard and the mounting surface; avoid long screws that could reach the fan motor. Regularly inspect the guard for deformation or buildup of dust and clean with a dry brush or compressed air to maintain airflow and cooling efficiency.
