1. Introduction In recent years, much longer life and environment-
(1) High air flow (2) Long life (3) PWM control function
conscious product are required while market of information/communication device and recyclable energy
As for new models, high air flow and long life have been
are increasingly expanded. At the same time, in line with
achieved maintaining compatibility with the fan size and
demand for products to have higher performance and be
mounting hole positions of conventional models.
more compact, there is also requirement for equipment to be higher-density and have more efficient internal cooling. Moreover, there is growing demand for fans installed in these products to be maintenance-free and have high air flow by having even longer life. Here we introduce features and abilities of three kinds of high air flow and long life fans “San Ace 60L”, “San Ace 80L” and “San Ace 92L” 9LG, developed in response to this kind of market demand.

2. Background of the Development Sanyo Denki has produced and sold long life fan, L-type so far. However, as already mentioned, according to the longer life of communication devices, reusable energy devices and environmental business devices, the higher equipment impedance due to high density equipment and the greater heat generation, a demand has emerged for replaceable parts such as the cooling fan to have much
Fig. 2 Profile of new“San Ace 80L”model
longer life and higher air flow in order to enable the maintenance-free of long-term use devices. However, it was impossible to increase air flow of the conventional long life fans in order to respond to these demands, therefore Sanyo Denki developed the three kinds of new 9LG fans which achieve both long life and high air flow.
3. Product Features Fig. 1, 2, and 3 show photographs of three new models. The features of these new models are as follows:

7. Conclusion Here we introduced some features and performances of three newly developed high air flow, long life fans “San Ace 60L”, “San Ace 80L”, and “San Ace 92L”. The new models have achieved significantly higher air flow and longer life while maintaining mounting compatibility with conventional model (L type). This means that, although less number of fans and less equipment space

1. Introduction In recent years, much longer life and environment-
(1) High air flow (2) Long life (3) PWM control function
conscious product are required while market of information/communication device and recyclable energy
As for new models, high air flow and long life have been
are increasingly expanded. At the same time, in line with

demand for products to have higher performance and be
mounting hole positions of conventional models.
more compact, there is also requirement for equipment to be higher-density and have more efficient internal cooling. Moreover, there is growing demand for fans installed in these products to be maintenance-free and have high air flow by having even longer life. Here we introduce features and abilities of three kinds of high air flow and long life fans “San Ace 60L”, “San Ace 80L” and “San Ace 92L” 9LG, developed in response to this kind of market demand.

2. Background of the Development Sanyo Denki has produced and sold long life fan, L-type so far. However, as already mentioned, according to the longer life of communication devices, reusable energy devices and environmental business devices, the higher equipment impedance due to high density equipment and the greater heat generation, a demand has emerged for replaceable parts such as the cooling fan to have much
Fig. 2 Profile of new“San Ace 80L”model
longer life and higher air flow in order to enable the maintenance-free of long-term use devices. However, it was impossible to increase air flow of the conventional long life fans in order to respond to these demands, therefore Sanyo Denki developed the three kinds of new 9LG fans which achieve both long life and high air flow.
3. Product Features Fig. 1, 2, and 3 show photographs of three new models. The features of these new models are as follows:

7. Conclusion Here we introduced some features and performances of three newly developed high air flow, long life fans “San Ace 60L”, “San Ace 80L”, and “San Ace 92L”. The new models have achieved significantly higher air flow and longer life while maintaining mounting compatibility with conventional model (L type). This means that, although less number of fans and less equipment space
