Product Q&A

Q:Can this SDF fan realize both unidirectional air supply and bidirectional reversible ventilation?

Yes. It supports single-way fixed air feeding and bidirectional reversible operation. Forward and reverse rotation can be rapidly switched, reverse air volume nearly equals forward flow, suitable for construction air supply and fire smoke exhaust simultaneously

Q:How does the noise reduction structure work for subway pipeline ventilation?

Equipped with multi-layer muffling sections at air inlet and outlet plus internal sound absorption cotton, running noise is greatly lowered. It satisfies strict noise requirements for urban subway buried pipelines and nearby residential areas

Q:Is customized size, power and connecting flange available?

Full customization is supported. Multiple power grades, fan diameters and mounting brackets are optional; matched ventilation ducts and pipeline connection fittings can be supplied as project requirements
