Noiseblocker already have the largest range of fans aiming to be the quietest on the market. Noiseblocker eLoop fans are designed to reduce as much frame vibration as possible to avoid resonation being transferred into the chassis.The most striking feature of the Noiseblocker eLoop fan is a completely new wing design that makes noise levels in the air stream even quieter. This allows the use of a directed air flow with less wasted air flow.The new fans are based on the research findings of Dr. Rudolf Bannasch Bionikers, who has developed his research with the basic principles of the rotor loop. The new technology has been in development for the past two years, then brought to the development laboratory at Noiseblocker.Specification:- Dimensions: 120 x 120 x 25 mm- Speed: max. 400-1500 U / min- Airflow: max. 98.7 m / h- Starting voltage: 6 V- Power consumption: 0.95 W- Connector: 4-pin- Life Expectancy: 140,000 hours- Warranty: 6 Years
