Compressed air is available in almost every industrial setting. It can therefore be manipulated by a Fox Mini-Eductor to create vacuum that can be used to pump, sample, or mix other gasses or to evacuate a small volume.
Because mini-eductors have no moving parts, they offer the maintenance-free way to sample or exhaust corrosive, explosive, dust-laden, or high-temperature gases. Three standard Mini-Eductors are stocked that, although they resemble each other externally, have very different internal geometries. The motive nozzle orifice sizes are .015", .030" and .060", - with similarly proportioned internals. Motive air consumption varies, therefore, by a factor of four with each eductor size change, enabling users to choose a Mini-eductor that minimizes their consumption of compressed air, GN2, or other gas.
