sanyo denki developed and produced long-life fan, l type (hereinafter“conventional model”) as high reliable fan in 1991 being pioneered in the market. ever since, we have built a strong track record for two decades or move. the first developed product was 120 mm sq., 38 mm thick fan size and we have enriched lineup to 8 sizes from 40 mm sq., 28 mm thick to 172 mm, 51 mm thick at present. 2.5 to 5 times longer life than general fans particularly satisfies needs of customers who require their equipment to be long-life and high reliability and those customers use the long-life fans in a variety of applications.  the trend in recent year s for information and communications devices to have high performance and down - sizing has resulted in higher - density devices. this has created a demand for cooling fans to achieve higher cooling performance (air flow - static pressure characteristics) without changing in size.  here we introduce technologies to improve fan reliability and ones mainly adopted for high air flow and long-life “san ace 60l, 80l, 92l” 9lg type (hereinafter “new model” ) that newly developed as cooling fan that increases cooling performance and has high reliability and long-life comparing to conventional model.  click here to read the full free engineering article in pdf.
