AeroV Backdraft Damper
Series 7400V: Vertical Blade, Medium-Duty, No Linkage
The AeroV Backdraft Damper is engineered to optimize fan array performance while simplifying the installation as a vertical blade damper.
- Self-contained blades fully enclosed in the damper frame allow direct installation without offsets or sleeves.
- Linkage-free design allows each blade to respond independently to pressure and airflow changes, improving efficiency.
- The blades self-close in response to negative pressure from backdrafts or recirculating air, preventing leakage.
- AeroV self-closes when a fan in an array shuts off, preventing leakage during downtime or failures.
- All-aluminum design provides a rust-free, long-lasting operation. The Celcon bearing, linkage-free design allows smooth, maintenance-free performance without the need for grease or lubricants.
- Designed for maximum energy efficiency, the AeroV produces a pressure drop of less than 0.01″ w.g. reducing system energy use while maintaining optimal airflow.

Series 7400V Medium-Duty, Vertical Blade No Linkage Backdraft Damper:
- Fan array intakes
- Air Handling Units (AHUs)
- Wherever reverse airflow prevention is necessary.
- Retrofit or addition to an existing fan array.
Durable, low-leakage performance under high static pressures.
SW – Salt Water Resistance:
Specifically designed for environments where there is salt spray or salt content in the air. Aluminum frame, blades, and axles are clear anodized to a minimum depth of 0.7 mil (18 microns). All zinc-plated steel hardware is replaced with stainless steel hardware.
SF – Silicone-Free:
Blade seals are extruded EPDM and frame seals are extruded TPE.
