UltraFlo Technology

You have probably heard that Attic Breeze products move more air than any other solar attic fan on the market and perhaps you have wondered, "What makes Attic Breeze so special"?  We call it UltraFlo® technology and it's what puts the performance in Attic Breeze fans.  UltraFlo is a combination of airflow physics, fan design, and engineering, which together allows our fans to offer the highest conversion efficiency (cfm/watt) of any solar powered ventilation product available.  In simple terms, Ultraflo allows our proprietary fan blade design to operate at its optimum efficiency point, producing most airflow possible for least amount of energy consumption.

Ultraflo technology puts the performance in Attic Breeze solar attic fans!

The physics behind UltraFlo technology involves utilizing basic venturi airflow mechanics.  It is well known that with any venturi design, a pressure differential will develop based on the flow of air or fluid through the venturi.  The faster the flow through the venturi, the greater the pressure differential.  A great example of this venturi effect can be seen with the nozzle on your garden hose.  When applied to the design of attic fans, this venturi effect can be used to increase the performance of the fan by taking advantage of the resulting increase in air density.  The result can be an increase in airflow performance by as much as 10% versus straight cylinder type fan housing designs.  However, utilizing the venturi effect properly is completely dependent on having the correct fan design, blade pitch, nozzle to blade diameter ratio, and many more factors, and that's what Ultraflo is all about.

Ultraflo in Action

As hot attic air is drawn into the solar attic fan, the airflow stream is squeezed through the venturi style fan housing.  This venturi effect produces in an increase in airflow density at the fan blade, maximizing conversion efficiency.  The higher the airflow, the more efficient our fans operate.  And higher efficiency means more airflow production per watt, allowing Attic Breeze to lead the industry in ventilation performance.
