When working underwater, choosing the right breathing apparatus is crucial, because it directly relates to the safety of the diver's life. For PAPR (Powered Air Purifying Respirator) respirators, while they are typically used for air purification in terrestrial environments, special considerations are required for use in underwater environments.
Special requirements for underwater work
The underwater working environment is very different from the land environment, so the requirements for breathing apparatus are also different. When working underwater, the respirator needs to be able to resist water pressure, prevent water from entering the system, and maintain a good seal. In addition, the underwater breathing apparatus also needs to be able to provide an adequate oxygen supply and be able to remove exhaled carbon dioxide.
PAPR respirator features for underwater work
Waterproof performance: The housing and components of the respirator must be able to withstand a certain depth of water pressure to prevent water infiltration.
Tightness: All connections and interfaces must be tightly sealed to prevent water from entering.
Oxygen supply: The respirator should be equipped with a reliable oxygen source and be able to supply oxygen continuously and steadily underwater.
Carbon dioxide removal: Breathing apparatus should effectively remove exhaled carbon dioxide and maintain air quality.
Pressure resistance: The respirator should be able to withstand high-pressure underwater environments and will not be damaged by pressure changes.
