Application
The Taco VorTech
®
 Air Separator is 
designed to provide an enhanced 
level of air removal in hydronic 
heating, cooling or combinational 
systems. Air is quickly and effectively 
separated and vented through a 
factory installed Taco 3⁄4” Hy-Vent
®
up to a maximum pressure of 150 psi 
and a maximum temperature of 240°.
Operation
The VorTech
®
 Air Separator features a primary separation 
chamber where the process of air elimination is controlled 
and optimized. The specially designed tangential primary 
chamber creates a swirling effect, or “vortex,” similar to a 
tornado. This swirling effect forms a low-pressure area in 
the center of the chamber. Air is drawn toward this lower 
pressure, and then once there it moves freely upward and out 
through the Taco 3/4" Hy-Vent
®
. Combined with the Bubble 
Breaker Cartridge and a downward direction change in the 
flow of water before exiting, air is quickly and effectively 
removed from the system.
