Description
AE1800 & AE1800R Series — Stainless Steel Air Eliminators
The AE1800 & AE1800R Series Stainless Steel Air Eliminators are engineered for the efficient removal of air and gases from liquid systems without allowing liquid to escape. By using a stainless steel float mechanism, these units automatically vent air from piping systems, process lines, or vessels whenever air accumulates. When liquid enters the body of the eliminator, the float rises and closes the valve, preventing any fluid loss. Designed for high durability and corrosion resistance, these air eliminators are suitable for industrial fluid systems requiring dependable automatic air removal.
Constructed with a stainless steel body and internals, the AE1800 (non-repairable) and AE1800R (repairable) models offer long service life in demanding environments. Available in orifice sizes ranging from 0.078" to 0.125" and threaded NPT connections, they support operating pressures up to 400 PSIG, making them ideal for a wide range of liquid piping applications.

Operating Principles
The AE1800 Series Air Eliminators function by allowing trapped air or gases to rise within the unit’s body, where a stainless steel float mechanism controls the venting process. When air is present, the float drops and opens the valve, allowing gases to escape. When liquid enters, the float rises and closes the valve to prevent fluid discharge. This automatic action ensures consistent system efficiency and prevents issues such as pump cavitation, flow interruption, and air binding.
These eliminators are ideal for liquid processing lines, pressure vessels, cooling systems, pump systems, and any application where trapped air negatively affects performance.
