Positive Pressure Compressed-air Breathing Apparatus

Provides breathing protection for users in the environment filled with poisonous air or lacking in oxygen.

WE-ZYS01 Positive Pressure Compressed-air Breathing Apparatus is a kind of isolated breathing protection apparatus. It provides breathing protection for users in the environment filled with poisonous air or lacking in oxygen. When it is used normally, the pressure inside the veil is always higher than the outside environment. It prevents the poisonous air from entering the veil, so as to protect the users. This product can be used in fire fighting, petroleum, chemical, metallurgy and electric power industry and so on. Standard: according with GA124-2004 Positive Pressure Compressed-air Breathing Apparatusstandard.

SABR-D Silicon Rubber Veil:

1. Designed according to the Asians face profile; unique double-antifog function; eyeclass adopting antifog technique; the fog can be disposed through the breathing airs scour toward the veil.

2. The external surface of the eyeclass adopting the most advanced rigidification technique in abroad.

3. Made by special aviation material.

4. Fillet with meshy structure.

5. Spherical Wide View: ≥95%;

6. German type interface port.

DV-D PLUS Air Feed Valve:

1. Valve quickly linking with veil by 360 degree, operating quickly.

2. Small volume, providing broad eyesight for the users.

3. Air feed according to demand; the biggest amount of air feed is beyond 550 litre per minute; users can breath comfortably and easily under intense movement.

Gas cylinder and gas cylinder valve:

1. Carbon fiber made gas cylinder, high intensity, light weight.

2. Aluminium alloys internal tank; corrosion-proof; excellent in cushion effect.

3. Y-type auto-locking structure, in order to avoid opening the gas cylinder valve because of the misoperation.

4. Robber cover to protect the cylinder;

5. Screw Thread of the mouth: M18*1.5, comply to the standard:

    HSE-AL-FW1, HSE-AL-FW2, prEN 12245;

6. The standard configuration is 6.8L; can choose 4.7 L or 9L; can choose 4.7*2 and 7.8*2 double-cylinder according to the demand.

8. According with America DOT-CFFC-2000 standard.

9. According with Chinese GA124-2004 standard.

BP-ASIA Backboard:

1. Designed according to Asians bodily form; according with human engineering pricinple, national design patent;

2 . Having good joint attribute; can bend along with bodys movement;

3 . So far, the lightest backboard in the world; the weight of main part is only 0.685kg;

4 . Aiguillette and girdle adopting Nomex flame-retardant materials.

PG-S Pressure meter & Annunciator:

1. Putting the annunciator and pressure meter in front of chest, so that the user can read pressure the easily hear the alarm sound;

2. The noctilucent function of pressure meter helps users to read the pressure data in the sombrous light;

3. When the pressure in the valve is lower than 5.5±0.5Mpa, the annunciator will alarm automatically. The alarm sound can last 8 to 10 minutes with 6.8L valve.

PR-1100 Relief Valve:

1. Fouction: reducing the high pressure air in the cylinder to middle pressure with about 7bar and then sending it to the air feed valve through the middle pressure pipe;

2. Small and delicate structure; safety valve adopting high-tech nanotechnology;

3. Adopting German technique; life-span is beyond 15years; highly realiability and stability;

4. Having Safety Relief Valve; preventing the high pressure air from entering the middle pressure system accidentally; when the middle pressure is higher than 1.1 -1.7Mpa, pressure can be relieved automatically to ensure the users safety;

5. The biggest amount of air feed is beyond 1000L per minute; making an assurance of users breathing;

6. Having other interface for the other user to breathe.
