Air Eliminators

Air entrapped in a piping system leads to airlock that prevents the proper filling of a piping system, corrosion, and even complete shutdown of a system. If air collected in a system is not properly vented out, this will even result in the explosion of the piping unit since air easily gets mixed with the fuel at high velocity.

Most of the liquid fuels, gasoline, LPG, diesel oil, and kerosene are likely to foam and expel out air /vapor. Air mixed with the liquid fuel disrupts accurate liquid measurement, aggravates the speed of the meter unit, causes wear, and ultimately leads to complete breakdown of the unit. Hence, it is vital to eliminate air and vapor from the liquid before they flow into the measuring unit. Even volumetric devices like positive displacement and turbine meters fail to distinguish liquid from air and vapor. Our air eliminators and combination air eliminator strainers are recommended for use in process applications involving heavy oils.

Our Air eliminators are installed on the upstream of flowmeters.They reduce the velocity of the liquid fuel thereby decreasing the intensity of air and vapor formation. The little vapor or air that rises up is collected at the top of the liquid tank, while the clean liquid is displaced through the discharge pipe. A float-operated valve opens to expel the air and vapor collected at the top of the tank. After the air is evacuated completely, the liquid fuel starts filling into the tank, closing the float-operated valve.

The back pressure at the outlet of the eliminator regulates the liquid discharge rate. We recommend for the installation of a back pressure valve, if the pressure differential fails to provide appropriate discharge rate.
