It is a multi-functional SCBA that is protected from oxygen deficiency and toxic gases generated 

at a fire suppression site(approximately 45 min.)The fire-fighting Self-contained Breathing Apparatus(KD-F45) 

used for fire suppression and rescue activities is a multifunctional that maximizes convenience and stability 

with electronic pressure gauges (PASS), fast charging devices, and height-adjustable moving.

* Electronic pressure gauge with built-in personal alert sound system(PASS)

* Excess flow valve function
* One-touch cobra buckle
* A two-stage regulator
* FBO of demand valve
* Wide full-face facepiece
* A flashlight of backplate
* Coummunication KIT with face conduction coummunication system
* Backplate that can adjust the height and adjust the movement
* Type 4 composite cylinder with weight reduction of 20% or more
* A quick-fill system

⦁ The supply valve shall have a BY-PASS device, which is an emergency valve 

   that can receive air in the container through a separate air pipeline in case of an emergency, 

   and a PURGE device for supplying air or removing residual pressure.

⦁ When the face is removed, a RESET button is installed to block the air without locking the container valve.

⦁ The backplate must be a moving structure that can move in three dimensions 

   according to the wearer's movement, and also a structure that can adjust the height of the wearer.

⦁ The backplate is equipped with a flashing device to identify the location of the air respirator wearer 

   and guide the rescuer in a dark place. If the residual pressure in the cylinder is less than 75 bar, 

   the flashing light will turn red and it will be easy to check the shortage of pressure between workers.

⦁ The electronic pressure gauge can intuitively check information such as residual pressure, 

   ambient temperature, and usable time of the container, and also has a flashlight function and 

   personal alert sound system(PASS) function that sounds alarms (visual and auditory) 

   when the user is not moving.

⦁ The Self-Contained Breathing Apparatus shall consist of a facepiece, a backplate, a regulator, a cylinder, etc.

⦁ The cylinder valve shall have an Excess Flow Valve function to prevent rapid air leakage 

   due to damage, etc. and to prevent the risk of the cylinder flying on its own.

⦁ A quick-fill system must be installed to rapidly charge high-pressure air to fellow members 

   while wearing Self-Contained Breathing Apparatus(SCBA).

⦁ The composite cylinder must be a material that prevents foreign substances from occurring 

   with a plastic (PET) liner.

⦁ It must be a type approved product by the Korea Fire Institute (KFI).
