4 Inch Metal Cooling Fan Grill Guard (120mm)

Description

The 4 Inch Metal Cooling Fan Grill Guard is a simple yet crucial safety component for any project utilizing exposed cooling fans. Designed to perfectly fit standard 120mm (4-inch) AC or DC cooling fans, this metal guard acts as a physical barrier to prevent fingers, stray wires, or loose debris from coming into contact with high-speed rotating fan blades.

Available at Tomson Electronics, this fan grill is constructed from sturdy steel wire with a corrosion-resistant plated finish. Unlike dense plastic mesh filters or stamped metal covers, the concentric wire ring design offers maximum safety while presenting virtually zero restriction to airflow, ensuring your power supplies, 3D printers, or amplifiers stay properly cooled without generating excess wind noise.

Frequently Asked Questions (FAQ)

Q: Will this fit my standard 120mm PC case fan?
A: Yes! In the electronics and PC industry, a "4-inch" fan grill is the exact standard size used to cover a 120x120mm cooling fan. The mounting holes will align perfectly.

Q: Does this grill include mounting screws?
A: No, this listing is for the metal grill only. You will need to use standard fan mounting screws (or standard M4/M5 bolts depending on your enclosure) to attach it to your fan.

Q: Does this filter out dust?
A: No. This is a wire finger guard designed for physical safety and maximum airflow. If you need to keep dust out of your enclosure, you should look for a 120mm mesh dust filter instead.
