The Imperial Manufacturing VT0072 4-inch fresh air intake hood provides a durable and weather-resistant solution for managing exterior ventilation termination points. Engineered from heavy-duty galvanized steel with a clean silver finish, this surface-mounted wall cap allows fresh ambient outdoor air to enter residential or commercial ventilation structures smoothly and continuously.
This robust intake hood incorporates a fixed louver design optimized to facilitate maximal airflow while deflecting wind-driven rain and snow away from the duct entrance. Additionally, the hood comes equipped with a built-in plastic pest guard screen that reliably stops birds, insects, and small rodents from accessing or nesting inside the home's ductwork.
This 4-inch collar fitting is suitable for mounting on brick, concrete, or exterior siding surfaces, making it highly versatile for diverse building envelopes. When completing a new heat recovery ventilator or bathroom fan layout, verify that this 4-inch diameter matching sleeve aligns with your interior vent pipe sizes to establish an airtight, code-compliant connection.
