Natural Smoke Ventilation
Passive smoke extraction systems that use natural airflow principles to safely remove smoke and heat during emergencies.
Reliable Passive Smoke Control
Natural smoke ventilation systems harness the principles of buoyancy and wind pressure to remove smoke and heat from buildings without requiring mechanical power or complex control systems.
These systems are cost-effective, energy-efficient, and highly reliable, making them ideal for warehouses, retail spaces, and industrial buildings where large-scale smoke clearance is essential.
System Benefits
- ✓No power consumption or ongoing energy costs
- ✓Minimal maintenance requirements
- ✓Operates independently of building power supply
- ✓Cost-effective installation and operation
- ✓Compliant with BS EN 12101-2 standards
- ✓Weather-resistant design for long-term durability
How Natural Smoke Ventilation Works
Heat & Smoke Rise
Hot smoke rises naturally due to buoyancy, creating pressure at ceiling level
Automatic Opening
Temperature-activated vents open automatically when preset temperatures are reached
Natural Extraction
Smoke and heat escape through roof vents, drawing fresh air in at low level
Key Operating Principles
Stack Effect
Hot smoke creates pressure differences that drive natural airflow upward and out of the building.
Wind Pressure
External wind conditions enhance the ventilation effect by creating additional pressure differentials.
