Certification status, customer case references, and several sustainability and traceability controls are not provided or remain unknown. Financial records are referenced for 2021–2023, but no non-monetary evidence in the slices establishes financial strength.

Product Q&A
Q:How powerful are duct fans?
A:
Duct fans range in power from less than 100W to more than 1,000W. A 1,000-watt fan is suitable for residential use, while 1,000W to 2,000W is suitable for industrial settings.
Q:Do duct fans increase static pressure?
A:
Yes, duct fans can increase static pressure, which is essential to enable air to move through the duct system, especially when there is friction resistance and external factors that may impede airflow.
Q:Can duct fans reduce static pressure?
A:
While primarily used to increase static pressure, they can also reduce it when set to a lower speed, when not sized properly for the system, or if there is a leak within the duct system.
Q:How noisy are duct fans?
A:
The sound level typically ranges between 3.6 and 7.0 sound levels. 3.6 is comparable to a refrigerator, while 7.0 is similar to background noise in a busy office. Installed fans do not cause interference.
Q:How do you maintain long-term business relationships?
A:
We maintain good quality and competitive prices to ensure customer benefits. We respect every customer, regard them as friends, and sincerely conduct business.
