Air Ejectors, N2 Ejectors, Natural Gas Ejectors, Hydrogen and Fuel Cell Ejectors

Air ejectors use compressed air or other gasses to create vacuum that can exhaust, vent, or evacuate.
Air Ejectors


Liquid Eductors

Liquid eductors, or jet pumps, use water or other liquids to create vacuum that can be used to suck in other liquids for mixing, diluting or creating solutions: to exhaust gasses.
Liquid Eductors


Slurry Eductors

Slurry Eductors are used to introduce solids into liquids with no moving parts. They are an ideal way to continuously produce solutions or well blended slurries and are commonly used in chemical, food, power, pharmaceutical, and waste water applications..

Mini-Eductors

Mini-eductors are 1/4" eductors used for small sampling, vacuum-generation, evacuating, and mixing applications. They can use very low flow rates of compressed air or water to create significant vacuum.
