SCBA (Self Contained Breathing Apparatus)

 

1. The main purpose and scope of application

1.1 The main purpose

RHZKF series of positive-pressure air breathing apparatus is an open-air self-contained breathing apparatus. This series of products are widely used in fire fighting, chemical industry, shipbuilding, petroleum, metallurgy, electricity, warehouses, laboratories, mines and other departments, for firefighters or emergency rescue personnel in smoke, gas, steam and oxygen and other conditions can be safe and effective conduct of fire fighting, disaster relief and rescue work, firefighters, and rescue and ambulance personnel to the ideal of personal respiratory protection equipment.

1.2 Scope

 A. smoke hypoxia and there is gas, smoke, steam pollution, atmospheric environment;

 B. -30 ° C ~ +60 ° C, relative humidity 0 ~ 100%, atmospheric pressure 70Kpa ~ 125Kpa of the atmospheric  

environment.

2. The main technical parameters

2.1 The technical parameters

RHZK-6/30	6	30	1800	300	5~6	60	≤14	77×30×48
RHZKF-2/30	2	30	600	300	5~6	20	≤4	77×30×48
RHZKF-3/30	3	30	900	300	5~6	30	≤4.5	77×30×48
RHZKF-6.8/30	6.8	30	2040	300	5~6	60	≤8.5	77×30×48
RHZKF-6.8X2/30	13.6	30	4080	300	5~6	120	≤14.5	77×30×48
RHZKF-9/30	9	30	2700	300	5~6	90	≤11.5	77×30×48

2.2 The use of time is calculated (taking an approximation, 1MPa ≈ 10KG)

Maximum working hours (Min) ≈ cylinder pressure (Mpa) × cylinder capacity (L)

0.098 (Mpa) × air consumption per minute (L / Min)

Note: Consumption per minute according to co-moderate labor intensity of the lung approximately 30L/min.

Special Note: product inspection and delivery of inspection, the cylinder gas storage pressure should be greater than 27MPa.
