Key Features

• Vertical Air Discharge: Ensures effective upward air movement while preventing rain entry into the building.
• Robust Construction: Made with galvanized steel components with a corrosion-resistant finish for enhanced durability.
• Reliable Backdraft Prevention: Fitted with gravity air-operated backdraft shutters for effective airflow management.
• Flexible Mounting Options: Available with flanged bases for circular ducts and flues, or square bases for square upstands.
• High-Velocity Design: Optimized for high air discharge velocities to prevent rain intrusion.

Construction Details

• Backdraft Shutters:
  • Sizes 31 to 80: Constructed from aluminum.
  • Sizes 90 to 200: Made from galvanized sheet steel.
• Cowls: Fabricated from galvanized steel for strength and durability.
• Corrosion Resistance: All steel components are treated with a corrosion-resistant finish.

Applications

• Ducted Systems: Suitable for installations requiring vertical air discharge with rain prevention.
• Industrial and Commercial Ventilation: Ideal for reliable air exhaust in buildings with remote fan mounting.

Important Notes

• High-Velocity Optimization: Designed for efficient air discharge at high velocities. For applications with low discharge velocity, alternative solutions such as Alpha Relief Air Vents are recommended.
• Wind Resistance: For areas prone to high winds, the addition of magnetic latches is recommended to secure shutters.
• Installation: Ensure the shutter hinge points down the slope of the roof for optimal performance.
