• Plug-in structure to quick connect with demand valve.
• Leak tight mask is made of high quality flame resistant silicon rubber, oronasal cover use top silicon rubber, soft and high temperature resistant.
• Flame resistant reticulated hood and strap are easy to wear.
• Adopt high-intensity sound transmission diaphragm.
• Oronasal guard suitable for wearers, decrease the inhalation carbon dioxide content.

2.    KL99-A02 backboard

 It is designed according to ergonomics to fit different users.The main body's weight is only 0.685kg. The tortuosity can be above 90 degree. It is made from a high strength material, which is chemical, high temperature and impact resistant.

3.    KL99-A03 warning whistle and pressure gauge

• The pressure gauge is specified by scale ranged between(0-40)MPa, it is connected with the Reducer through a high pressure hose. The dial plate is made of fluorescent material, which enables user to read the figure in darkness.
• The gauge surface is made of shock resistant material, protected by rubber cover, and is waterproof, quakeproof, and dustproof. 
• The alarming device is designed on the high pressure hose close to the pressure indicator. When cylinder pressure is below(5.5+ 0.5)MPa, the alarming whistle will sound alarming at above 90d B(A). 

4.    KL99-A04 backpack

Back plate assembly consists of back plate, shoulder strap, waist belt, buckle, pressure reducer holder and cylinder fastener. Back plate is designed according to ergonomics, complying with the back shape of human body, making wearer more comfortable with a larger interface. It is injection moulded by flame resistant engineering plastics and carbon fiber, it is of high intensity and shock-resistance to protect from being damaged, while weight is only 0.68kg. Shoulder straps and belt are made of Nomex or KEVLAR, tear-resistant and flame-retardant. And they together distribute the weight of the apparatus effectively. Pressure reducer which is fixed by drift bolt on back plate can be replaced easily.

5.    KL99-A05 air supply valve

• Demand valve, with small size, can be inserted mask in 360o promptly. Gas supply is above 500L/min.
• Streamlined and elegant design, do not obstruct view
• Manuel close valve has small resistance for opening
• Small breathing resistance to make respiration comfortable
• Easy operation and use
• Ensure safe air supply by using manual force air supply button
• Outer shell uses flame resistance high intensity engineering plastics

6.    KL99-A06 decompressor

The pressure reducer core adopts advanced technology with a design life of 15 years. The unique maximum gas supply is above 1000L/min, ensuring the user's enough respiratory volume.

The main parts that connected with the reducer:

• Single or double cylinder
• The medium pressure hose whose function is to supply air to the demand valve
• The high pressure hose connected with the pressure indicator

7.    Gas cylinder and cylinder valve

Y shape design, with safe self lock device to prevent inadvertent close due to hard knock or incorrect operation.Unscrew the switch handwheel by rotating in the counterclockwise direction, it is regarded as the open condition and close vice versa. There is safety diaphragm set in cylinder valve, with explosion pressure at (37-45)MPa to prevent the deformation and explosion of cylinder due to inner high pressure.

8.    Mulfunctional fast join valve

Stainless steel, strong and durable. Traceless design, safe and reliable.
 

9.    The configuration can be 2L/3L/4.7L/6.8L/9L

Carbon fibre cylinder has the advantages of high strength, light weight, corrosion-resistant and anti-shocking.

Carbon fibre composite cylinder, inter layer is made of high intensity aluminum alloy

fully wrapped with carbon fiber composite. The glass fiber surface screw is M18*1.5.
