Product Description

 

En137 Approved Self-Contained Open-Circuit Positive Pressure Air Breathing Apparatus (SCBA)

The self-contained positive pressure air breathing apparatus of KL99 series, which is a kind of isolated protective breathing equipment, provides respiratory protection for users working in oxygen-deficient environment or the environment with toxic and harmful gas. Under normal conditions, the pressure in the respirator mask is a little higher than the pressure in external environment, which can effectively prevent external toxic and harmful gas from intruding into the mask, and guarantee the safety of users.

The product can widely apply to such industries as fire fighting, petroleum, chemistry, metallurgy, power, shipping, , public security, etc.
The air cylinder can be 3L/4.7L/6.8L/9L/12L-carbon fiber composite air cylinder or 3L/6L/6.8L/12L-steel cylinder (for ship use).

A complete set contain with parts as following:

1. KL99-A03 Back plate assembly

Lightweight, easy to use, comfortable. Lumbar pad for added back support. No tools required for easy maintenance.

Backplate 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.
