SFN-DBL Series – Dual-Stage Centrifugal Special Fan

The SFN-DBL is a dual-stage centrifugal fan engineered for high-pressure industrial processes. Designed with two backward-curved impellers arranged in series, it delivers enhanced pressure capabilities while maintaining high efficiency and low noise levels. Its compact structure makes it suitable for space-constrained installations, while the rugged steel frame ensures durability in continuous-duty environments. Ideal for systems with high resistance or multiple filtration stages.
