The word 'airer' is derived from 'air' (from Old French *air*, meaning the invisible gaseous substance surrounding the earth) and the suffix '-er' (meaning a person who). An 'airer' refers to a person who deals with or is associated with air, often in contexts like air quality or aerodynamics.
Think of someone who is connected to 'air' — the suffix '-er' indicates a person, so an 'airer' is someone who works with or relates to air.
