1. KL99-A01 Full mask

Three-dimension spherical visor. The visual field could reach 91% with great optics. The lens has been rigidified and anti-fog processed thus can be without fog on surface for long time.

Fit for people's face, comfortable donning and good leak tightness.
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 Audible warning device 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, quake-proof, and dust-proof.

The alarming device is designed on the high pressure hose close to the pressure indicator. When cylinder pressure is below(5.5±0.5)M Pa, the alarming whistle will sound alarming at above 90d B(A).

3. KL99-A03 Back plate assembly

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 0.68 kg. 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.

4. KL99-A04 Demand valve

Demand valve, with small size, can be inserted mask in 360⁰ 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

5. KL99-A05 Pressure reducer

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

6. Cylinder valve

Y-shape design, with safe self lock device to prevent inadvertent close due to hard knock or incorrect operation.Unscrew the switch hand-wheel 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.

7. Mulfunctional quick-release buckle

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

8. Composite cylinder will be 2L/3L/4.7L/6.8L/9L

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

11. HBCS skull communication system

It comprises microphone, horn, loudspeaker, talk-listen button, connecting wire and receiver
The sending/receiving communication system and horn are installed inside the helmet; the transceiver is installed at the top of the helmet and the horn is installed at ear position.

When it is used, the head will have small vibration when talking. The requirements of interphone dialog for loudness can be met through amplification and filtration, and the communication effect can be guaranteed even under a complex environment Flame retardant and high temperature resistant ally material is used, which ensure good impact resistance and that it can be used safely under various sever environments.
It can be used with intercoms of different types. The operation is simple and it is unnecessary for training.
