6.8L Marine equipment self contained breathing apparatus
Self contained air breathing apparatus (SCBA) is designed for protecting:
1)Toxic particles and aerial fog
3)The oxygen concentration is less than 17%
4)The smog caused by fire disaster
Remark:The SCBA has the function of respiratory protection and face protection.
When used in bad working environment,be sure to use auxiliary protective equipment at the same time,such as:Protective Gloves,Safety Boots,Airtight protective clothing,Safety helmets.
We also offer OEM service.
The SCBA is an assembled product,it consists of a variety of standard part,it can meet the needs of respiratory protection.
The volume of gas cylinder (2L,4.7L,6.8L,9L,12L etc) and quantity of gas cylinder (single/double).
The SCBA provides user sufficient air by equipped with one or two gas cylinder.The air is compressed to store in the gas cylinder (the pressure of the gas cylinder is 30MPa).But the air in the gas cylinder can't be breathed by user immediately.It must be decompressed twice through the related parts.First,the pressure regulator decompresses the high pressure air to 0.7MPa,and then transporting it into the medium-pressure pipelines, at last,throug the air supply valve,the air is decompressed again to the positive air which can be breathed by the user.
Because the air provided by air supply valve is positive air,the pressure inside the face mask is always higher than outside working environment.So the toxic gas and aerosol and smog can't enter into the face mask,which fully protect the safety of users.
The back-plane is designed according to the ergonomics totally.
Work pressure of the alarm whistle is 5.5±0.5MPa.
The whistle will alarm until the air exhaust.Caution:When the whistle alarms,the user must leave the working place immediately and then evacuated to safe area.
Air consumption is 5L/minute.
Sound level is 90db.
Frequency is 3800HZ.
