FAQ

Q1: What types of transformers are your low noise cooling fans suitable for?
A:
Our low noise cooling fans are widely used for oil-immersed power transformers, dry type transformers, wind/solar power station transformers, box-type substations, and various industrial transformer cooling systems.

Q2: What is the noise level of your cooling fan?
A:
The noise level of our fans is typically ≤70 dB(A), depending on the model and size. We also offer ultra-low noise models with noise levels as low as 63-65 dB(A), suitable for urban and residential substations.

Q3: What is the typical air flow capacity?
A:
Our fans offer air flow from 3000 m³/h up to 30,000 m³/h depending on the fan diameter (commonly 700mm, 900mm, 1000mm, and 1200mm models).

Q4: Can the fan work in outdoor or harsh environments?
A:
Yes. Our fans are designed for outdoor use with IP55/IP56/IP65 protection grades. The anti-corrosion coating ensures long service life even in high humidity, salt spray, or industrial chemical atmospheres.
