SX and SXT series fans.
fans have the highest airflow to nise ratio than any
other fans in its class. The spacially designed blade
reduces air noise keeping the overall operating noise
below an audible level. Max noise is rated at 14dBA
while delivering 32 CFM of airflow. Most fans running
with low noise levels only produce about half of the
SX and SXT models feature a removable blade prop.
This allows for easy cleaning and re-lubrication.
When properly maintained these fans will run for many
years providing more airflow with less noise.
SXT fans have a thermistor probe which varies the speed
of the fan based on temperature. When cool the fan will
run at about 1200 rpm. As heat increases the fan speed
will increase gradually up to 2400 rpm.
SX series fans are a fixed speed at 1600 rpm also producing
32 CFM of airflow. Rated at only 14 dBA it is virtually
silent. Perfect for home theater applications.
