SheeChung RV Furnace Vent Screen 7.5″x4.1″ Bug Screen

The SheeChung RV Furnace Vent Screen is engineered to fit most Duo‑Therm, Atwood, and Suburban furnace vents, measuring 7.5″ L × 4.1″ W × 1.3″ H. Its 0.2mm precision grids form an impenetrable barrier against flies, bees, mice, and other pests, preventing wasps from nesting and protecting your fan motor from costly damage.

Designed with an arched profile, the screen maximizes airflow while evenly distributing wind pressure during high‑speed travel, ensuring the screen stays securely attached. A rubber gasket creates a flush seal against the vehicle surface, eliminating metal‑to‑trailer contact scratches. Installation is straightforward: use the included spring clip and tool to attach the screen to the furnace vent.

Constructed from heavy‑duty stainless steel, this bug screen resists deformation, corrosion, and high furnace temperatures, delivering reliable performance in all outdoor conditions. Whether you’re on the road or parked, the SheeChung screen keeps your HVAC system free from pests and debris, extending the life of your RV’s ventilation system.
