In every high-rise building, hotel, or shopping mall, peoples' lives are safer with a good SHEVS (Smoke & Heat Exhaust Ventilation System). A jet fan ventilation system is for normal ventilation and to extract smoke in case of emergencies.
Building Regulations specify what is required to maintain safe conditions in a car park. Smoke control systems are a requirement, but the technology and fire engineering may appear complex at first glance.
The system should limit the concentration of CO within the car park to below 30ppm (averaged over eight hours). Fire protection consultants only consider extracting up to 10 air changes per hour for smoke clearance. It refers to the number of times the volume within the car park changes within one hour.
Extract fans should be fire-rated at 300°C for one hour. Jet fans replace ductwork and drive fumes or smoke towards extract fans – keeping pollution within acceptable levels and clearing smoke. Here are the advantages of using a jet fan ventilation system in your building.
- Space Saving – Jet fan systems are more discrete and take up significantly less space than ducted systems.
- Saves Energy - The fans are frequently integrated with CO detection to commence CO management. You can control the fans to dilute pollutants without operating needlessly.
- Low Noise – They produce less noise. The primary extract fans are smaller and run at lower speeds than standard systems.
- Cost-Friendly – Jet fan ventilation systems are less expensive than ducted systems, and they are easier to install and maintain.
