Honeywell positive pressure air respirator supplier

Honeywell C900 Pro Positive Pressure Air Breather 6.8L Carbon Fiber Gas Cylinder Air Breather SCBA105KP

1. PANO Classic Yellow Full Face Cover

Suitable for Asian face shape, comfortable to wear

Wide field of view, higher safety

Equipped with a five point headband, it is fast, easy, and stable to wear

Reduce the CO2 content exhaled from the mask

The internal airflow of the face mask automatically flushes the screen design, which can efficiently avoid the generation of fog

The interior of the screen also has an anti fog coating to further prevent the generation of fog

Can withstand high temperatures of 950 degrees Celsius

The screen meets EN136 Class 3 rating (capable of withstanding high-speed particle impacts at 190 meters per second)

2. Gas supply valve

The gas supply valve is equipped with an automatic positive pressure mechanism, which is convenient to connect with the mask, has a reasonable structure, and is not easy to separate from the mask

Lightweight and compact in structure, quickly connected to the face mask through spring buttons

Can be connected to the mask at any angle of 360 degrees, without the need for any tools, and can be operated with one hand or bare hands

After inserting the mask, the air supply valve automatically supplies air without the need for negative pressure activation, making it convenient for users who lack experience in using respirators

When disconnected from the mask, the air supply valve automatically stops supplying air, reducing air loss

The gas supply valve has a static positive pressure automatic adjustment function of 3 millibars inside the mask

When the user experiences breathing difficulties, the gas supply valve will automatically increase the gas supply to 450 liters per minute (rapid gas supply)

Press the yellow button on the gas supply valve to obtain a constant gas supply of 500 liters per minute

3. Pressure reducing valve

Made of nickel plated brass with high pressure resistance, equipped with an automatic compensating balance piston to maintain the medium pressure at 8 ± 2 bar

When the pressure exceeds 13 bar, the safety valve automatically opens to ensure user safety

4. Alarm whistle

Retaining the traditional mechanical alarm whistle, it can also provide an alarm sound greater than or equal to 90db

For safety reasons, the mechanical alarm whistle cannot be stopped by the user after being triggered. The alarm whistle will always sound until the air in the cylinder is exhausted

5. Fully wrapped carbon fiber composite gas cylinder

High strength integrated aluminum alloy inner liner, middle layer wrapped with high-strength carbon fiber, and outermost layer wrapped with glass fiber

The gas cylinder is equipped with a rubber backing and protective ring to protect the surface of the cylinder from damage

Each gas cylinder has been appraised by a qualified pressure vessel appraisal agency and labeled with an inspection label

Chinese identification (selling unit, working pressure, hydrostatic test pressure, service life, serial number, thread size, etc.)

The fluorescent label is sealed inside the surface of the bottle, making it easy to quickly confirm the user's position in the dark and further enhancing safety

Inflatable medium: Compressed air

Domestic ordinary gas cylinder

Technical performance of C900 self-contained open circuit compressed air respirator

6. Gas cylinder valve

Adopting a right-handed handwheel design, it is convenient for users to open

The opening direction is counterclockwise

7. Back frame and strap components

The back frame is made of high-strength nylon and fiberglass

Designed ergonomically with a large opening on the back frame, it is lightweight and sweat wicking

The gas cylinder strap can be adjusted freely and can be used with various types of gas cylinders. The strap buckle is convenient for quick locking or opening

The back frame, straps, and related straps are all made of anti-corrosion and flame-retardant materials, with a usage temperature of -40 ° C to+140 ° C and a flame retardant combustion test of up to 800 ± 50 ° C

Strap straps with easy to maintain design, convenient for use and maintenance

Both the shoulder strap and waist belt have luminous warning strips for easy use at night and in dark places

The back frame assembly is suitable for 4.7L, 6L, 6.8L, and 9L

The high and medium pressure pipes are hidden in the backboard pipeline groove to reduce the risk of tripping during operation

8. High pressure and medium pressure pipes

The high-pressure pipeline was tested according to the method specified in GB16556. The high-pressure pipeline was subjected to 1.5 times the rated working pressure of water pressure for 2 minutes without any leakage or abnormal deformation

The medium pressure tube is tightly attached to the body trunk when the respirator is in the carrying state, which does not affect the user's work and free movement of the head

The medium pressure airway material is made of high-strength odorless synthetic rubber, which will not cause ventilation obstacles when the wearer's movements cause the airway to bend or deform

The burst pressure of the medium pressure airway shall be at least 5 times the output working pressure of the pressure reducer

The appearance quality of the airway shall be manufactured in accordance with the provisions of GB 1189
