A trompe is a water-powered air compressor, commonly used before the advent of the electric-powered compressor. A trompe is somewhat like an airlift pump working in reverse.

Trompes were used to provide compressed air for bloomery furnaces in Catalonia^[1] and the USA.^[2] The presence of a trompe is a signature attribute of a Catalan forge, a type of bloomery furnace.

Trompes can be enormous. At Canadian Hydro Developers' Ragged Chute facility in New Liskeard, Ontario, water falls down a shaft 351 feet (107 m) deep and 9 ft (2.7 m) across to generate compressed air for mining equipment and ventilation.^[3]
