[Cools at -15°C Below Ambient Temperature] Siroca to Launch Handy Fan with 'Cooling Plate' for Direct Skin Cooling!

Siroca Co., Ltd. (Chiyoda-ku, Tokyo) will launch a handy fan on May 25, 2026, equipped with a cooling plate that allows you to cool down by applying it directly to your skin.

With 'extremely hot days' where the temperature is almost the same as body temperature continuing, and summers getting hotter every year. As summer arrives earlier and the heat lingers into early autumn, heat countermeasures are essential. Handy fans are an item that can be easily carried outdoors, but on 'extremely hot days' with temperatures over 35 degrees Celsius, just blowing air can turn it into hot air, which can be counterproductive.

Siroca is newly launching a handy fan equipped with a 'cooling plate' that is also useful for heatstroke prevention by directly cooling areas with large blood vessels, such as the nape of the neck. This product allows you to take measures against the heat by using it in different ways: in the hot outdoors, cool your skin directly with the cooling plate in addition to the airflow, and in moving trains or on your desk indoors, you can cool off with the airflow.

The air volume has a total of 4 levels: low, medium, high, and turbo. By optimizing the blades, guard, and motor, the wind speed has increased by about 1.45 times compared to our company's previous models, achieving a powerful air volume. In addition, due to improved battery performance, the continuous use time when used at a comparable wind speed is 4 hours longer*1 than the previous model. You can use a more powerful wind for a longer time. The main body is designed to be folded 180 degrees for compact storage, so it does not take up space in your bag when moving.

This summer, why not take measures against the heat with Siroca's handy fan with a cooling plate?

Product Features 1. **Cooling Plate for a Lasting Cool Sensation** 2. **Powerful Airflow for Solid Cooling** 3. **Folds 180 Degrees for Compactness. Convenient on a Desk too** 4. **Designed for Safe and Long-Lasting Use**

### 1. Cooling Plate for a Lasting Cool Sensation

Equipped with a metal 'cooling plate' that becomes cool to the touch, about 15°C below the ambient temperature*2. It helps prevent heatstroke by cooling large blood vessels, such as those in the nape of the neck.

The cooling plate (Peltier type) has the characteristic that when the surface cools, the back surface generates heat. To prevent the surface temperature of the cooling plate from rising, we have adopted a unique structure for heat dissipation, maintaining a cool sensation of about 15°C below the ambient temperature*2 for a long time.

### 2. Powerful Airflow for Solid Cooling

The air volume has a total of 4 levels: low, medium, high, and turbo.

Utilizing the 'Fuwa-Vroom Technology' that Siroca has cultivated in its fan series so far, the blades, guard, and motor have been optimized. The wind speed has increased by about 1.45 times compared to our company's previous models, realizing an even more powerful wind.

Continuous use is possible for about 10.5 hours on low air volume and about 2.2 hours on maximum air volume (turbo).

*When the air volume is on turbo, the cooling plate cannot be used. If you press the cooling button when the air volume is on turbo, the air volume will automatically switch to high.

### 3. Folds 180 Degrees for Compactness. Convenient on a Desk too

A compact design where the head can be folded 180 degrees. It does not take up space in your bag when carrying it. If you bend and fix the head at your desired angle, it can also be used as a desk fan.

(Handheld, Neck-strap, as a Desk Fan)

### 4. Designed for Safe and Long-Lasting Use

**◆ Safe design to prevent battery temperature rise & malfunction** The main body uses a lithium-ion battery. A temperature sensor prevents abnormal temperature rises in the battery. If the battery becomes hot during use, the power is temporarily cut off to control the temperature rise. Furthermore, since the power is turned ON/OFF by long-pressing the button, it prevents unintended operations such as the power button being pressed in a bag and the power turning on by itself.

**◆ Long battery life** Equipped with overcharge and over-discharge prevention circuits. Suppresses battery deterioration.

*1 Comparison of continuous use time when the previous model (SF-H631) and the new model (SF-H751) are used at a comparable wind speed (SF-H631: Turbo / SF-H751: Medium). *2 [Measurement method] In a 35°C room, operated with low air volume and cooling button ON, and the difference between the room temperature and the surface temperature of the cooling plate was measured (in-house research).
