0 a device that removes mist (= a thin layer of water drops) from a car window, usually by blowing air on it
Partial evaporation is achieved, and the vapour passes through a demister before reaching the condenser section.
The cleaned gases are normally passed through a mist eliminator (demister pads) to remove water droplets from the gas stream.
The compressor centrifuges the pure water vapor after it is drawn through a demister (removing residual impurities) causing it to compress against tubes in the collection chamber.
Some changes to basic equipment level included a fresh air heater/demister, duo-tone paint in various new plain and pastel colours, brighter interiors and a windscreen washer.
This is the role of the demister.
