Smoke vent for roofs with efficient smoke and heat exhaust ventilation
The Ventia smoke vent is designed for roofs and developed to provide efficient smoke and heat exhaust ventilation in buildings where safe evacuation of smoke and hot gases is critical. The unit is electrically operated and CE-marked, making it a reliable solution for modern residential buildings, industrial facilities, and warehouses.
With an opening angle of up to 140°, Ventia enables rapid and effective ventilation in the event of a fire. The robust construction is designed for long-term performance and can also be used for natural comfort ventilation where required.
Ventia can be supplied in any RAL colour to match the building’s roof and architecture, offering a functional solution that combines safety, design, and flexibility.

CE-marked
Always read the installation instructions supplied with your order carefully before starting installation, as they may vary depending on configuration and selected options.
Refer to the separate manual for installation and connection of the control system.
Always follow the specific operation and maintenance instructions supplied with your order, as these may vary depending on model, material, and selected options.
Operation
- The hatch is part of the building’s smoke and heat exhaust system and is activated automatically via the control system
- Can also be used for natural comfort ventilation
- Always ensure the opening area is clear of obstructions before activation
Maintenance
- Functional testing should be carried out at least once per year or in accordance with applicable regulations
- Regularly check that the hatch opens and closes correctly during testing
- Inspect actuators, hinges, and mechanical components, and keep the unit clean from dirt and corrosion
What is a smoke vent?
A smoke vent is an openable roof hatch used to remove smoke and hot gases during a fire, improving visibility and enabling safe evacuation.
What is the difference between a smoke vent and a smoke exhaust ventilator?
The terms are often used interchangeably. The technical term is NSHEV (Natural Smoke and Heat Exhaust Ventilator), but “smoke vent” is more commonly used.
What does CE marking mean for a smoke vent?
CE marking confirms that the smoke vent meets EU construction product requirements and has been tested and verified according to relevant standards.
What is EN 12101-2?
EN 12101-2 is the European standard for smoke and heat exhaust ventilators. It defines performance requirements such as aerodynamic free area, wind and snow load, reliability, and temperature resistance.
What is aerodynamic free area (Aa)?
Aerodynamic free area (Aa) is the effective ventilation area of a smoke vent, used to design smoke ventilation systems according to EN 12101-2.
What is geometric opening area?
Geometric opening area is the physical opening size (width × length). In most cases, aerodynamic free area (Aa) is used for system design.
Can a smoke vent be used for ventilation?
Yes, many smoke vents also provide natural comfort ventilation in daily operation.
Do smoke vents require maintenance?
Yes. Regular inspection is required, typically at least once per year, to ensure proper opening, closing, and system functionality.
How many smoke vents are needed?
The number depends on building size, use, and fire safety requirements. It is typically calculated by a fire engineer based on aerodynamic free area (Aa).
Where are smoke vents installed?
They are installed on roofs or at the highest point of a building, where smoke naturally accumulates.
Can a smoke vent be used as a roof access hatch?
Yes, some smoke vents are designed to also function as roof access hatches, provided they meet safety requirements.
How does a smoke vent open in case of fire?
Smoke vents open automatically via a fire alarm system or control panel and can also be activated manually.
