HTF-type axial fire smoke exhaust fan‌ can operate continuously for more than 30 minutes under medium temperature conditions of 280°C and for 20 hours per cycle at 100°C without damage, serving both ventilation and smoke exhaust purposes.

The fan is classified by speed control methods into ‌single-speed, dual-speed, and variable-frequency‌ (with a variable-frequency motor and controller for adjustable speed, recommended frequency range: 25Hz–50Hz to adapt to different operational needs)‌.

Product Parameters

When a fire breaks out in a building, whether residential or industrial, it is necessary to extract smoke from the fire area to evacuate people and possible victims, protect the building structure and facilitate access for fire-fighting equipment. 

Applications

In car parks, ventilation can be natural or mechanical. In the latter case, Jet Fans must be installed to properly move the air and maintain the required conditions of safety and comfort under normal conditions, as well as in the event of a fire.

These ventilation systems extract the hot gases generated at the start of a fire and create smoke-free zones underneath the floating smoke layers, thereby improving evacuation conditions and facilitating firefighting. They also prevent secondary fires and control the temperature of the smoke to prevent a building from collapsing.

Pressurisation control systems protect evacuation routes in the event of fire by preventing the entry of smoke through air overpressure. If the doors are opened or in the event of air leaks, the system reacts by increasing the flow rate. This guarantees that the escape routes are always free of smoke in an emergency situation.

The reliability of the tunnel ventilation system is essential to ensure the safety of users over time. Tunnel ventilation can be natural or forced. In the last case, fans should be installed to generate adequate air movement to maintain safe conditions both in comfort mode and in case of emergency.
