Air breathing apparatus RHZKF6.8/A

Main technical parameters

Serial number	Inspection items		Standard requirements
1	Wear quality (kg)		≤18
2	Airtight performance of the whole machine		After the air tightness test, the pressure indicator value of the pressure gauge drops less than 2MPa within 1min.
3	Dynamic respiratory resistancePa	Cylinder pressure 30MPa ~ 2MPa, breathing volume 40 * 2.5L / min	Positive pressure is always maintained in the mask.
			The inspiratory resistance is less than 500Pa.
			Expiratory resistance less than 1000Pa
		Cylinder pressure 2MPa ~ 1MPa, breathing volume 25 * 2L / min	Positive pressure should still be maintained in the mask.
			The inspiratory resistance is less than 500Pa.
			Expiratory resistance less than 700Pa
4	High temperature resistance (Pa)		After high temperature test, all parts should be free from abnormal deformation, adhesion and degumming..
			Respiratory pressure should be maintained at 40 times / min and respiratory volume 100L / min. Positive pressure should be maintained inside the mask.
			Exhalation resistance≤1000Pa
5	Static pressure (Pa)		Static pressure≤500Pa
			And should not be greater than the opening pressure of the exhaust valve.
6	Low temperature resistance (Pa)		Respiratory pressure should be maintained at 25 times / min and respiratory volume 50L / min. Positive pressure should be maintained inside the mask.
			Expiratory resistance less than 1000Pa
			After the low temperature test, all parts should be free from cracking, shrinkage and brittle.
7	Medium pressure gas conduit		The medium pressure air duct does not interfere with the wearer's work and free movement of the head, and does not interfere with the connection between the air supply valve and the mask. When the movement of the wearer causes the bending deformation of the mid pressure trachea, there should be no ventilation disturbance.
8	All non-metallic parts have flame retardancy standards.

Through wireless transmission, the fighters can read the residual pressure information in real time through the state of the barometric indicator lamp, completely liberate their hands, and greatly increase the self-safety protection ability of the fighters in disaster rescue.

In the mask, under the eyes, flat with the nose and mouth, showing the location of the lamp on the right side. The green light is always on when the cylinder pressure is 10-30 Mpa, the yellow light is on when the cylinder pressure is 6-10 Mpa, and the red light is always on when the cylinder pressure is less than 6 Mpa, which reminds firefighters that the compressed air in the cylinder is about to run out. The fireman can observe the pressure condition of the cylinder at any time without looking at the pressure gauge.

After completing the wireless communication connection, the device converts the received barometric information into the color of the LED lamp to display.

Characteristic:

Wireless connection, real-time display of pressure margin information.

1 pairs of 1 exclusive pairs, and can be repaired at any time.

Low pressure alarm lamp and partner lamp reminder at the same time.

Intelligent lighting, automatically adjust the brightness of light.

Battery replacement is convenient, low power consumption and durable.
