Aeolus Series
• Blade Structure: Double-layered, aerodynamically arranged for maximum water diversion
• Material: Extruded aluminum (lightweight and corrosion-resistant)
• Drainage System: Internal rainwater collection and outward directional discharge
• Installation: Flush with rooftop or raised installation, rectangular or drum-shaped profiles available
• Blade Heights: 300mm (Aeolus300) / 500mm (Aeolus500)
Product Overview
The Aeolus Series from Togen features a line of labyrinth-style natural ventilators designed for industrial roofs. Available in Aeolus300 and Aeolus500, these horizontal louver systems operate without external power, utilizing pressure and temperature differences to achieve continuous natural ventilation. With 100% rain protection and exceptional wind resistance, Aeolus louvers are a high-efficiency solution for ventilation louvers in metal buildings and industrial facilities.
Key Features
• Zero-Energy Natural Ventilation powered by stack effect and thermal uplift• 100% Rainproof at 2.5 m³/s airflow (per BSRIA 13030 standard)
• Wind resistance up to 80 m/s and snow load up to 500 kg/m²
• Horizontal louvers with double-blade waterproofing
• Noise attenuation inserts for cooling tower and loud industrial zones
• Free area: 51% (Aeolus300) / 60% (Aeolus500)
Noise Control Performance
Each blade can be fitted with a noise attenuation panel (150mm–1000mm height), ideal for:• Cooling tower top noise reduction
• Simultaneous ventilation and sound suppression
• Industrial sites with stringent decibel limits
Noise-reducing inserts are parallel to the blades and preserve airflow effectiveness.
Optional Motorized Models – Aeolus300D / Aeolus500D
• Integrated motorized roof opening units atop the Aeolus louvers• Supports electric or pneumatic actuators, linkage with fire systems
• Closable via control box when passive ventilation is not needed
• Maximum single unit size: 2.2m × 10m; site-assembled units up to 2.5m × 10m
