Model SX40 Silent Fan
The SX40 model fans provide the quietest cooling solution for it’s size. Recommended where quiet cooling is required. The
SX40 fans provide 6 CFM of airflow while running at a whisper quiet 14 dBA. When combined on the one rack space panels,
airflow adds up to 36 CFM on the 6 fan model SX640 and SP640X. The special blade design creates more airflow with less
noise than ball bearing type fans while running at very low noise levels.

Operation:
Mount in desired location for optimal cooling. Intakes are best positioned lower or adjacent to equipment.
Exhausts are best positioned at the top or above equipment. Connect power.
Maintenance:
Cleaning the fan is the best preventative maintenance. Cleaning frequency would depend on the environment. It
is recommended that the blade be cleaned to prevent any buildup of dust. Canned air works well.
Blade Removal:
For cleaning and maintenance, the blade prop can be removed.
Grasp the blade prop and pull straight out of the fan body. Inspect the shaft and lubricate if needed. Any oil will
work; light grease works best. Clean blade as needed with a dry cloth. Soap and water can be used if needed, but
should be thoroughly rinsed and dried before use. Reinstall the blade; when properly installed the blade will snap
into place. Cleaning and inspection of the blade shaft should be done annually for best performance.
Warranty:
2 Years from the date of purchase.
