Cooling
Fans Generate Extreme Air Pressure
Jaro
Thermal
has added two new sizes to its ultra-high-static
pressure Revolution series of brushless dc fans. The new sizes
specifically address the market's increasing demand for maximum
performance, capability, lower power consumption, and
specific size. The 140-mm x 140-mm x 51-mm tops out at 316
CFM with 0.83 inches of static pressure and the
120-mm x 120-mm x 38-mm delivers 262 CFM
with 1.2 inches of static pressure.
When
tested at 3600 rpm over a 0- to 300-CFM range of airflow, the 140-mm
x 140-mm x 51-mm Jaro fan achieved equal or greater static pressure
than a comparable competitor’s unit. The performance advantage
for Jaro was mainly in the 200- to 300-CFM range where the Jaro fan
exhibited roughly 5 mm of greater pressure than the competitor’s
model. Similarly, when tested at 6000 RPM over a similar range
of airflow, the 120-mm x 120-mm x 38-mm Jaro fan
achieved equal or greater static pressure than a competitor’s
model. In this case, the Jaro fan’s performance advantage
appeared over the 100- to 275-CFM range and amounted to roughly 0 to
5 mm of higher pressure.

Revolution series fans combine a superior fixed-blade design
with a
slick air-guiding frame to maximize static pressure while also
optimizing air flow.
