In cascade systems, what two components separate oil and water from breathing air?

• A. Cartridge Filtration System and a Separator
• B. Filter Housing and a Dryer
• C. Separator and Receiver
• D. Cartridge Filter and a Dryer

Answer: (A)

The idea being tested is how cascade systems remove liquids and aerosols from breathing air through two stages: filtration first, then separation. A cartridge filtration system handles particulates and many oil aerosols, protecting the downstream stage. The separator then acts on the remaining liquid droplets, coalescing oil and water so they can be drained away, effectively removing these liquids from the air you breathe. A dryer removes moisture in the form of water vapor, not liquid oil/water droplets, and a receiver mainly stores pressurized air rather than separating contaminants. So, the combination of a cartridge filtration system and a separator is the correct pairing for removing oil and water from breathing air.
