防油ファン・耐温ファン・耐Gファンの特長

装置の用途や性能に合わせて，ファンも特殊な環境に設置される場合があります。山洋電気はみなさまの装置が使われる環境に合わせて，特定の耐久性のあるファンをご用意しています。今回は， 防油ファン・耐温ファン・耐Gファンをご紹介します。

防油ファン

標準ファンは油がかかると内部の電気部品に悪影響を及ぼして故障してしまいますが，防油ファンは，油がかかるような環境でも使用できます。防油対策をしたファンと標準ファンとの大きな違いは2つあります。

1. The motor and circuit board, which are electrical components, are coated with resin to prevent water and oil from penetrating (Figure 1).
2. By widening the gap between the blades and the frame, the blades are prevented from locking due to oil adhesion (Figure 2).

Wide Temperature Range Fan

Many standard fans will break down or stop working properly if they exceed the operating temperature range (-20℃ to +70℃) on either the high or low side. By strengthening the temperature resistance of the fan, it can operate in environments with harsh ambient temperatures.
SANYO DENKI 's Wide Temperature Range Fan can be used in a wide range of temperature environments, from -40°C on the low side to +85°C on the high side. A wide operating temperature range has been achieved by using structures and circuits that allow components that are sensitive to both low and high temperatures to function without problems in either case.

G Proof Fan

The "G" in G-resistance stands for acceleration. Fans installed in devices such as CT scanners are subject to high centrifugal acceleration. Standard fan specifications are unable to withstand high centrifugal acceleration, and in the worst case scenario, the fan may disintegrate inside the device. G Proof Fan we have developed in recent years employs a highly rigid aluminum frame and a structure in which the blades and rotor cover are molded as a single unit, increasing the joint strength between the parts and enabling it to withstand high centrifugal acceleration.

As you can see, there are special environments in the world that standard fans cannot handle. At SANYO DENKI, we have applied the various technologies we have developed to strengthen the durability of our fans, making them durable themselves. This eliminates the need for countermeasures on the equipment side, contributing to the miniaturization of equipment and a wider range of operating environments. If you are having trouble installing a fan in a special environment, please feel free to contact SANYO DENKI.
