The explosion-proof performance of the YBF3 axial flow fan motor complies with GB3836.2 "Electrical equipment for explosive gas atmospheres - Part 2: Flameproof 'd'", and is designed and manufactured to incorporate the advantages of similar international products. It features the ability to prevent internal explosions from transmitting outward. Additionally, it boasts small size, high efficiency, large temperature rise margin, low noise, and excellent start-up and operational performance. The explosion-proof markings are dI, dIIAT4, dIIBT4, and dIICT4, which are suitable for coal mine underground and factory environments where flammable gases or vapors of IIA, IIB, IIC classification and temperature groups T1 to T4 form explosive mixtures with air. ExdⅡBT4 is suitable for environments with explosive gas mixtures.
This series of electric motors is compatible with the T35 series explosion-proof axial fans.
Protection Rating: Main Shell IP44, Terminal Box IP54
Cooling Method: IC0141 Insulation Class: B
The YBF3 Axial Flow Fan Motor is our company's upgraded explosion-proof motor replacing the original YBF series motors. It is designed and manufactured to match explosion-proof general-purpose fans. This series of electric motors conforms to the power ratings and installation dimensions of the International Electrotechnical Commission (IEC) standards, with the corresponding relationship identical to the German DIN42673 standard, facilitating the matching of export equipment and the procurement of spare parts for imported equipment.
Features: Higher efficiency (exceeding GB18613-2006 Level 3 standard) compared to the original series of motors, compact size, lightweight, attractive appearance, safe and reliable operation, long lifespan, excellent performance, easy installation, use, and maintenance. ExdI is suitable for underground coal mine environments where explosive mixtures of coal dust or other combustible gases are present, excluding mining areas.
This series of electric motors is compatible with the T35 series explosion-proof axial fans.
