Green fans produce more pressure with less power
An Aerco product story
Edited by the Electronicstalk editorial team Aug 21, 2008
Dual-blade design with improved aerodynamics avoids airflow separation and results in more efficient performance, saving energy while reducing operating noise levels.
New from Aerco is a range of fans from Delta that uses a highly efficient dual-blade design with improved aerodynamics that avoids air flow separation and results in a more efficient performance thus saving energy while reducing operating noise levels.
Available in 120, 92 and 80mm frame sizes, the Delta QFR green fans produce typically 70% more pressure and use 40% less power with extremely low noise at full speed.
For example the 120 x 120 x 38mm fan produces airflow of 81.7 litre/s at 5000rev/min and has a power consumption of 16W - an improvement of 33% compared with a typical conventional bladed fan of this size.
There is also an improvement in acoustic noise of 5dBA.
With a life exceeding 70kh, measured with L10 at 40C, the QFR series is RoHS compliant and will prove ideal for use in modern telecommunication and computing equipment in servers, computers and PCs.
Waterproof versions are also available.
