Dayton Compact Axial Fan Filter and Guard Assembly, For Fan Size 3-1/8", Polyurethane Foam

Axial fan guards with filters combine a protective barrier for fan blades and filtering media for cleaning air as it's pulled into the fan. The guards are grilles or grates that mount to the fan housing to allow airflow while enclosing the blades to prevent damage or accidental contact. The filters are sheets of replaceable media that fit behind the guards to keep debris and contaminants from entering the fan and the enclosure. Fan guards with filters are typically used on fans operating in busy, dusty 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.
