Dayton Aluminum Fan Filter Guard Assembly, 1 EA,For Fan Size (In.) 4-11/16

Shielded axial fan guards are tightly woven metal mesh guards that mount to a fan housing to protect the fan blades, filter out contaminants, and shield against electromagnetic and radio frequency interference. They allow airflow while enclosing the blades to prevent damage or accidental contact. Their tight-weave construction acts as a filter to remove debris and contaminants before they enter the fan and the enclosure. They're made of materials that provide EMI-RFI shielding, so they're often used on enclosures that contain computer equipment and other sensitive electronic components.

Compact axial fan guards and filters are fan attachments that block out debris to reduce the risk of damage to fans and enclosure components. They are sized to fit compact axial fans. Fan guards enclose the blades of a compact axial fan to help shield them from airborne debris or accidental contact. Fan filters fit behind a guard to help prevent dust and debris from building up on the fan blades and entering the enclosure, where it could damage components.
