The JK-Y790 residual pressure monitor is a wind pressure measurement system specifically designed for the accurate measurement and control of positive pressure values in the front rooms (including independent front rooms, shared front rooms, and shared front rooms) and stairwells of buildings, as well as in the positive pressure supply systems (i.e. smoke prevention systems in buildings). It ensures that the residual pressure values in the front rooms and stairwells relative to the evacuation corridors are within the range required by national regulations, thereby ensuring that the smoke prevention systems in buildings can function normally without affecting the normal evacuation of personnel.

When a building is hit by a fire, smoke proof staircases, front rooms, and refuge floors are life passages for personnel evacuation and passages for firefighters to extinguish fires, and must ensure high requirements for their smoke proof performance.
Ensure that the residual pressure in the evacuation route is effectively controlled during a fire, in order to prevent the spread of smoke and make it easier for survivors to open the fire prevention measures.
