The Delfield 3516178 Freezer Fan Guard covers the fan area in compatible commercial freezer equipment. Made from clear plastic and measuring 6-7/8 inches in diameter, it provides a barrier around the fan while allowing the assembly to remain visible. Its position helps reduce unintended contact with moving fan components without unnecessarily blocking airflow. https://partsfe.com/fan-guard-6-78diameter-for-delfield-part-3516178
