The InLine Fan grid aluminium filter InLine 33374A is a 40×40 mm grille with an aluminium filter element designed for 4 cm (40 mm) fan diameter. Constructed from silver aluminium, the grille provides a balance of airflow and particulate capture for small ventilation and cooling fans. The product is intended for use in ventilation applications where a compact, durable air inlet or outlet filter is required.

Advantages

How to use

Install the grille over the fan opening, aligning the mounting holes with the fan or enclosure. Secure with appropriate screws or fasteners; ensure the grille sits flush to avoid vibration. Periodically inspect and clean the aluminium surface to remove accumulated dust using a soft brush or damp cloth. Replace if the grille is damaged or deformed to maintain effective airflow and protection.

Recommendations

For optimal performance, use the grille with fans specified as 40 mm diameter and check clearance inside the enclosure to avoid contact with moving fan blades. Regular cleaning prolongs service life and preserves airflow.
