- Duct - have special mounting flanges and are mounted in a prepared section of the air duct.
- Wall - installed in a wall ventilation window or panels.
The devices are selected taking into account the dimensional parameters of the installation location. An important condition is that the body of the smoke removal valve must fit tightly and hermetically to the mating surface of the wall or pipe.

The design of the smoke removal system is coordinated with departmental supervisory structures. It indicates a schematic installation location and the main technical parameters of the smoke exhaust valve:
- Air flow capacity when the flap is open.
- Opening method using an electric drive - automatic or at the command of a dispatcher.
- Fire resistance limit - for this type of equipment E90 or E120 (the numbers indicate the time the geometry is preserved at critical temperatures).
