Product Description

Material & Structure
Material: Made of stainless steel, featuring excellent corrosion resistance and weather resistance, ideal for outdoor installation.
Structure: Self-drooping louver design – the louvers open automatically during exhaust and close tightly when idle, enabling one-way airflow to prevent backdrafts, insects, rainwater, and debris from entering.
Appearance: Square panel that fits flush with the wall for a clean, aesthetic look, with pre-drilled screw holes for easy and secure installation.

DimensionsPanel Size: Both 5-inch and 6-inch models share the same outer frame dimensions of 185mm × 185mm, ensuring consistent mounting openings for easy replacement.
Duct Interface Difference: The key distinction lies in the rear duct interface diameter: the 5-inch model is 121mm, while the 6-inch model is 145mm, designed to match ventilation ducts of corresponding sizes.
Depth Difference: The 6-inch model has a slightly longer projection length of 75mm, compared to 70mm for the 5-inch model, to accommodate larger ducts.

Key Advantages of Square Self-Drooping Louver VentOne-Way Airflow Control: Self-closing louvers allow exhaust air to exit freely while blocking backdrafts of cold air, rain, pests, and debris.
Stainless Steel Durability: Corrosion-resistant, rust-proof, and weatherproof construction ensures long-lasting performance in outdoor or high-moisture environments.
Energy Efficiency: Prevents conditioned indoor air from escaping when the dryer is idle, reducing heating/cooling costs.
Easy Installation & Maintenance: Compact square design fits standard ducting; smooth stainless steel surface is easy to clean and resistant to lint buildup.
Quiet Operation: Precision-engineered louvers open and close smoothly with minimal noise during dryer operation.
Fire Safety: Non-combustible stainless steel material complies with building safety standards for dryer exhaust systems.
