Midori Anzen's “COOLFAN” is an innovative workwear equipped with dual battery-powered fans on both sides of the waist area. These fans enable sweat evaporation by drawing in outside air and channeling it throughout the garment, thereby creating a constant airflow within the garment itself. This process can enhance efficient heat dissipation which results in comfortable cooling sensation for users.

COOLFAN also provides protection from heat-related hazards including heat stroke, and enhances personnel work efficiency in high-temperature environment, particularly at construction sites, manufacturing facilities, and outdoor work locations where air-conditioning is difficult.
Among the COOLFAN product offerings is an industry-first in Japan, the COOLFAN EP – a body-cooling solution for environment where product explosion-proof requirement is mandatory.
