isolation breathing protection SCBA air supply unit on trolly
>>> Overview
Movable long-tube positive pressure air breathing apparatus is a kind of safe and reliable breathing protection equipment that is convenient to maintain and can be used for long time. This model of breathing equipment can replace any air cylinder without affecting its use and able to work continuously.
As the breathing equipment has tight structure, easy to operate, portable structure (convenient cart), operators don't carry heavy items such as back-up and air cylinder etc. It has such features as light, convenient to move, especially suitable to work at narrow places such as long time maintaining, inspection, clearing up, painting and smelting work at such places with thick smoke, poisonous gas or anoxia inside oil tank or engine room. Usually, it's used for occasions as petrochemical industry, aerospace, underground coal mining, nucleus plant, chemical plant, painting industry, metallurgical industry, fire fighting, underground pipeline and sewage and gas pipeline etc.
1. KL99-A01 full mask
A complete set contain with parts as following:
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 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.
