足立機工 List of Products and Services

We offer the "Ultra High Temperature Furnace Circulation Fan," which enables operation in the MAX 1200°C range that was previously only possible with water cooling, now achievable with air cooling. By using air cooling, the need for equipment such as piping and pumps required for water cooling is eliminated. Additionally, there is no concern about water leaks. It also accommodates a direct coupling structure, making maintenance easier compared to belt systems. Currently under verification for hydrogen and ammonia atmospheres. 【Specifications】 ■ Operating Temperature: Max 1200°C ■ Airflow: ~300m3/min ■ Static Pressure: ~100Pa ■ Motor: ~5.5Kw ■ Rotational Speed: ~1200min-1 ■ Rotor Diameter: Φ400～φ800 *For more details, please download the PDF or feel free to contact us.

Adachi Kiko has launched a circulation fan for industrial furnaces that can withstand internal temperatures of up to 1200 degrees Celsius. By accommodating ultra-high temperature ranges that were previously difficult to use, it contributes to the high efficiency and energy saving of heat treatment. The diameter of the propeller for in-furnace stirring is less than φ800, and it is currently being tested for compatibility with hydrogen and ammonia atmospheres. *For more detailed information, please refer to the PDF document. Feel free to contact us for further inquiries.

We have developed a "furnace circulation fan" that can withstand temperatures up to 1200°C. Its main role is to promote the scorching of the furnace atmosphere (stirring and circulating the air inside the furnace). The presence or absence of a circulation fan in industrial furnaces significantly affects energy costs. In heat treatment furnaces using gas burners, installing a fan can achieve energy savings of up to 30% in gas consumption. 【Features】 ■ The fan stirs and circulates hot air within the furnace to equalize temperature distribution. ■ Installing a fan can achieve energy savings of up to 30% in gas consumption. *For more details, please download the PDF or feel free to contact us.

This product is a limit load fan that has a limitation on operating power, meaning that even if the airflow increases, the power does not rise beyond a certain point. Due to its ability to achieve a large airflow in low-pressure areas, it is widely used in plant equipment and general intake and exhaust applications. Please feel free to contact us when you need assistance. 【Features】 ■ There is a limitation on operating power, and even if the airflow increases, the power does not rise beyond a certain point. ■ A large airflow can be obtained in low-pressure areas. * For more details, please download the PDF or feel free to contact us.
