Fan guard / grill 140mm by Ohne hersteller, model FGR-140S, silver protective fan cover

140mm fan guard (grill) by Ohne hersteller, model FGR-140S in silver finish is a metal protective cover designed to fit standard 140 mm axial fans. It provides a physical barrier that prevents accidental contact with spinning blades and reduces the risk of foreign objects entering the fan assembly. The guard mounts over the fan frame and is intended for use in PC cases, server racks, electrical enclosures and other cooling installations where a sturdy metal cover is required.

Advantages

The silver metal construction offers mechanical protection and improved durability compared with plastic alternatives. Its form factor matches standard 140 mm fan frames for straightforward installation. The open grill design ensures minimal airflow obstruction while still shielding internal components and fingers from the fan blades. The neutral finish integrates with a range of equipment interiors and rack-mounted systems.

• Protecting 140 mm axial fans in PC cases and gaming rigs
• Use in server racks and data center enclosures
• Industrial and laboratory cooling installations with exposed fans
• Equipment cabinets and electrical enclosures requiring blade protection

Key specifications

How to use

Place the guard over the 140 mm fan frame so that mounting holes align with the fan or chassis screw points.

Verify clearance and rotation after installation to confirm unobstructed airflow and safe operation.

Recommendations

For best results, use corrosion-resistant screws in environments with elevated humidity and periodically inspect the guard for deformation or debris buildup. When installing in high-vibration applications, check fasteners regularly and retighten as needed to maintain a secure fit.
