The Falex Air Jet Erosion Test System controls a repeated impact erosion approach involving a small nozzle delivering a stream of gas containing abrasive particles which impact the surface of a test specimen. The amount of weight loss per unit of time represents the erosion or wear rate, providing laboratory scale erosion measurements under a range of conditions. The Test System may be used to rank the erosion resistance of materials, coatings, platings, epoxies, weldments, sprays, paints, and similar products under the controlled conditions of the test.

The test system uses dry air (100 psi max) and a nozzle tube to control particle velocity and an adjustable media feed nozzle to control the particle feed rate of the abrasive impacting the test sample. An adjustable test sample holder controls the angle of incidence from 15° to 90°.

The test system accommodates standard or user selected abrasive media. The distance from the nozzle to the flat specimen surface is adjustable and is controlled with a micrometer. The test system includes a Start/Stop time controller and a mechanical jet flow shutter, and an exhaust vent (exhaust system not included).
