Центробежный шахтный вентилятор C-тип с регулируемой скоростью - экономичное решение от китайских поставщиков и фабрики
The pulley is mounted inside the inner bearings, which significantly reduces the axial dimensions and results in a more compact overall structure. This design is well-suited for scenarios such as small machine rooms, equipment mezzanines, and installations with limited lateral space, eliminating the need for significant additional installation areas and maximizing the use of space.
Without the need for variable frequency equipment, the impeller speed can be precisely adjusted by replacing pulleys of different diameters, adapting to changing airflow and pressure requirements. This speed adjustment operation is simple and significantly less costly than variable frequency upgrades, making it especially suitable for scenarios involving seasonal load fluctuations or requiring flexible parameter adjustment.
Transmission components such as belts and pulleys are easy to remove. No special tools are required for routine inspections, tensioning, or replacement. Wear parts (belts) have a low cost and a clearly defined replacement cycle (1–2 years). Basic maintenance can be performed by non-specialists, reducing operating costs and minimizing downtime.
The symmetrical dual-bearing support with pulleys positioned inside the bearings ensures more uniform force distribution, reducing vibration and wear caused by unilateral load. This provides reliable operational stability, extended bearing life, and a low equipment failure rate.
Compatible with various materials including steel and fiberglass-reinforced plastic (FRP), it can be adapted for use in specialized models such as corrosion-resistant (FC series) and general-purpose variants. Combined with various impeller configurations (forward/reverse), it is suitable for medium and low power applications including ventilation, small-scale exhaust gas purification, and auxiliary air supply for boilers, offering exceptional versatility.
