Air Respirator Specifications and Usage Guide
(A) Single-Bottle Air Respirator
1. Structural Composition: The single-bottle air respirator consists of several key components, including the back frame, gas cylinder, gas valve, pressure relief valve, face mask, pressure gauge, shoulder straps, and waist belt. These parts work together to provide a safe and efficient breathing system in hazardous environments.
2. Performance Characteristics: This model weighs 8.7 kg, with a cylinder volume of 6.8 liters and operates at a working pressure of 30 MPa. It can store up to 1,857 liters of breathable air, providing approximately 60 minutes of use under normal conditions. The air supply rate is 300 liters per minute, and the alarm activates when the pressure drops between 4 and 6 MPa.
(B) Bao Bao Single-Bottle Air Respirator
1. Structural Composition: Similar to the standard single-bottle model, the Bao Bao version includes a back frame, gas cylinder, gas valve, pressure relief valve, face mask, pressure gauge, shoulder straps, and waist belt.
2. Performance Characteristics: This unit has a slightly higher weight of 11.8 kg, with a larger cylinder volume of 9 liters. It also operates at 30 MPa, storing 2,460 liters of air, which allows for up to 90 minutes of continuous use. The alarm activates when the pressure falls between 4 and 6 MPa.
(C) Double-Bottle Air Respirator
1. Structural Composition: The double-bottle model includes the same essential components as the single-bottle versions, such as the back frame, two gas cylinders, gas valves, pressure relief valves, face mask, pressure gauge, shoulder straps, and waist belt.
2. Performance Characteristics: This unit weighs 18 kg and features two 6.8-liter cylinders, operating at a working pressure of 30 MPa. It provides approximately 136 minutes of use, with an air supply rate of 300 liters per minute. The alarm triggers when the pressure reaches 4–6 MPa.
3. Application: This type of respirator is primarily used in fire scenarios involving toxic gases and smoke, offering extended protection for emergency responders.
4. How to Use:
- First, check that the respirator is complete and in good condition, ensuring the pressure is at least 25 MPa.
- Adjust the shoulder straps and waist belt for a secure and comfortable fit.
- Connect the air supply valve to the mask and turn it clockwise until you hear a click, indicating a proper connection.
- Fully open the gas valve while monitoring the pressure gauge to ensure consistent airflow.
5. Important Notes:
- Ensure there are no facial hairs or beards that could interfere with the mask's seal.
- Always verify that the cylinder pressure is above 25 MPa before use.
- When the pressure drops to 4–6 MPa, the alarm will sound immediately, signaling the need to exit the area.
- Store the respirator in a room with a temperature of 5–30°C and humidity between 40–80%. Avoid areas with corrosive gases.
- If not in use for an extended period, keep the full-face mask in its natural state. Apply talcum powder to rubber parts to prevent deterioration and prolong the product’s lifespan.
