40,50,80,120mm Dustproof Cooler Fan Case Cover – Dust Filter – Dust Shield

This dustproof fan cover is a plastic mesh filter frame that slides over 40mm, 50mm, 80mm, or 120mm fans to block dust and debris, keeping your components clean without significantly restricting airflow. Available with or without an integrated dust shield, this dustproof fan cover gives you two layers of protection. The frame alone acts as a low-profile dust filter at 3.5–5 mm deep, while the with-shield version adds a removable foam pad for finer particle capture. As a result, it suits both intake fans where dust build-up is a real concern and exhaust positions where a clean appearance matters. Made in black plastic to blend with most cases and enclosures.
