New Cosmos Electric and Industrial University of Industry Joint Research Scientifically Verifies Heatstroke Prevention Effect of Explosion-Proof Fan-Integrated Wearable 'AIR FLOW PRO'

New Cosmos Electric Co., Ltd. (Headquarters: Yodogawa-ku, Osaka; President and CEO: Yoshinori Takahashi), which aims to "eliminate gas accidents worldwide," has conducted joint research with Yuta Sumita and Masatomo Horie from the Institute of Industrial Ecological Sciences, Department of Occupational Health Management at Industrial University of Industry, to verify the heatstroke prevention effectiveness of its explosion-proof fan-equipped wearable 'AIR FLOW PRO (Air Flow Pro).' The results were presented at the '99th Japanese Society for Occupational Health,' held on May 30, 2026.

This study newly confirmed that even under extremely severe heat stress conditions of 42°C ambient temperature and 50% relative humidity, wearing this product significantly suppresses increases in core body temperature and heart rate.

## Summary of Joint Research Results

A comparative experiment was conducted with 13 healthy adult males under an environment of 42.0°C ambient temperature and 50% relative humidity, comparing conditions with the fan 'operating' versus 'not operating.'

## Experimental Observations

- Suppression of core temperature rise: After 30 minutes of physical activity, rectal and esophageal temperatures showed significantly less increase when the fan was operating compared to when it was not (P<0.0001).
- Suppression of heart rate increase: The average rise in heart rate was reduced by approximately 21% (75 bpm without fan operation vs. 59 bpm with fan operation), confirming reduced cardiovascular strain.
- Reduced sweat production: Efficient heat dissipation (evaporative cooling) due to fan airflow resulted in a significant reduction in estimated sweat production (P=0.0405).

Even under harsh heat conditions of 42°C ambient temperature and 50% relative humidity—temperatures exceeding skin temperature—the use of explosion-proof, electric fan-equipped workwear significantly suppressed increases in core temperature, heart rate, and estimated sweat production. This garment is structurally designed to facilitate internal airflow circulation, and the research results indicate its potential to reduce heat stress for workers engaged in physical labor in explosion-proof areas such as chemical plants and gas terminals.

## Conference Presentation

## About the Explosion-Proof Fan-Integrated Wearable 'AIR FLOW PRO'

New Cosmos Electric developed the explosion-proof fan-equipped wearable 'AIR FLOW PRO' on June 24, 2025, believing that its long-standing passion for creating safe, secure, and comfortable environments—spanning over 65 years—and its explosion-proof design technology cultivated through gas detector development could contribute to heatstroke prevention in explosion-proof areas.

Immediately after launch, the product received numerous orders, with the first batch selling out. In March 2026, a new navy color, less prone to showing dirt, was added. High demand continues through pre-orders, and the company is receiving inquiries from many enterprises regarding adoption.

## Future Outlook

This academic presentation has objectively validated the effectiveness of 'AIR FLOW PRO' in protecting not only on-site 'safety' but also workers' 'health' with quantifiable data.

New Cosmos Electric will continue to contribute to the safety and health of all individuals working in harsh environments, alongside its mission of 'eliminating gas accidents worldwide.'

## About New Cosmos Electric

Since developing the world's first household gas alarm in 1964, the company has pursued its vision of 'eliminating gas accidents worldwide' by manufacturing household gas alarms, industrial gas detectors, and residential fire alarms. Its household gas alarms hold the top domestic market share, and the company is now actively expanding into overseas markets. Leveraging gas sensor technology—the core of all its products—it has developed numerous innovative products that did not previously exist.
