Dayton Compact Axial Fan Guard: Fits Square Fan Shape, 4 11/16 in Radiator Connection, 7/32 in Dp

Axial fan guards are grilles or grates that mount to a fan housing to allow airflow while providing a protective barrier for the blades. They help prevent damage to the blades by enclosing them to deflect debris and keep objects from being inserted into the blades. These guards also reduce the risk of injuries by preventing accidental contact with spinning blades. They're commonly used to cover fan blades in busy, accessible areas.

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.
