HTF-I-(A) fire and smoke exhaust fan products have passed the inspection by the Certification Center of the Fire Products Qualification Center of the Ministry of Public Security. They are certified with 3C, and can provide fire safety reports as well as shipping certificates.
Production workshop footage:
The fire suppression fans can provide inspection reports and 3C certificates!
For buildings with fire protection requirements, such as subways, tunnels, sports venues, high-rise buildings, underground shopping centers, workshops, ovens, etc., for fire suppression and ventilation, dual-speed motors are commonly used. Normally, they operate at a low speed for ventilation purposes. In case of a fire, they automatically switch to high speed through an electronic control system, quickly removing smoke within half an hour to enable personnel to evacuate safely and protect the country’s and people’s property and lives. The air delivered is non-flammable, non-corrosive to steel, and does not contain sticky substances. The dust and hard particles in the gas must not exceed 150 mg/m³. When used for ventilation, the inlet temperature must not exceed 80°C; when used for fire protection, the smoke temperature can continue to operate continuously for more than 30 minutes at 280°C.
