Product Q&A
Q:How powerful are your EC duct fans?
A:
Our EC duct fans come in a wide power range from 50W to 1,000W+, suitable for different ventilation systems. 100-300W: Home & small commercial spaces 300-800W: General duct ventilation / equipment cooling 800W+: Industrial high-airflow applications EC motors deliver higher efficiency at lower power consumption.
Q:Do EC duct fans increase static pressure?
A:
Yes. EC duct fans are designed to boost static pressure effectively, ensuring strong airflow even in long ducts or systems with high resistance. Their high-efficiency EC motors provide stable and reliable pressure performance.
Q:Can an EC duct fan reduce static pressure?
A:
Static pressure may decrease if: The fan speed is set too low The fan size is not properly matched to the duct system There is air leakage or blockage in the duct Correct sizing + EC motor speed control ensures optimal static pressure.
Q:How noisy are EC duct fans?
A:
EC duct fans operate very quietly, typically within 25-60 dB: 25-35 dB: Similar to a quiet refrigerator 40-55 dB: Similar to office ambient noise As they are installed inside ducts, noise transmission is further reduced. If noise increases, check for leaks, blockage, or loose installation.
Q:How do you ensure long-term cooperation?
A:
We offer stable quality, high-efficiency EC technology, and competitive prices. We value every customer, provide professional service, and aim for long-term win-win partnerships.
