Smoke removal system is one of the important components of a building's fire protection system. Smoke removal systems are required in areas where high concentrations of smoke, as well as health-hazardous gases, may form in the event of a fire.

Smoke removal system is a specially designed technical system of supply and exhaust ventilation, which can be controlled automatically or manually.

Main task of the smoke removal system is to ensure safe evacuation conditions for people in case of a fire at the facility.

Installation of the smoke removal system includes a number of works such as: installation of fire dampers, fans, and main duct network assembly.

According to building regulations, SRV (Smoke Removal Systems) equipment is required for high-rise buildings (over 10 floors), underground structures, and rooms without natural ventilation.

SRV systems are usually implemented with automatic control (integrated with the facility's comprehensive safety systems, automatic fire alarm systems, and automatic fire suppression systems) or with semi-automatic control (activation is performed by on-duty personnel or building occupants after receiving fire information).

In case of fire or smoke, the fire automation opens ventilation openings and hatches, activates roof fans to forcibly remove smoke and heat from the building. Proper operation of the smoke removal system provides additional time for people to safely evacuate the building engulfed in fire.
