Request selection
Provide the equipment type, airflow, static pressure, power, speed, supply and control requirements to help the engineering team begin motor selection.
Submit duty information for selection support
Why we ask these
Airflow and static pressure
The motor load on the same fan at 0 Pa and at 100 Pa are not remotely the same. Without static pressure, a power figure means little.
Lowest operating speed
Confirm the cooling-air source, fan drive, minimum continuous speed and thermal limits; the TEFC name alone is not enough.
Control method
It sets the integration effort. RS485 and 0–10 V differ considerably in cost to integrate.
Confirmed business contact details
The export contact is not yet factory-confirmed, so it is neither published nor used for routing. The confirmed contact is used for now, with the production address stated on the ISO 9001 certificate.

Company address
Floor 4, Building B, Dongao Xingu, 56 Fenglin Road, Zhonglou District, Changzhou, Jiangsu, China
The same address as the production site on the ISO 9001 certificate. The legacy English footer carried a second address in Niutang, Wujin District; until its role is confirmed it is not published alongside this one — two factory addresses in different districts read to an overseas buyer as a trading company. Its handling is explained on the Facility page.
The dedicated export recipient, response time and after-sales owner still require written factory confirmation. No automatic split or response-time promise is made until then.
Information to prepare before selection
- 01Equipment and sizeFan type, impeller diameter or unit model
- 02Operating pointTarget airflow and static pressure, ideally the usual working range
- 03Speed requirementMaximum and minimum speed, and how much time is spent at the low end
- 04SupplyPhases, voltage, frequency, and whether voltage fluctuates
- 05Control interfaceWhat protocol the supervisory system uses, and whether feedback is needed
- 06Mounting and environmentMounting form, space limits, humidity, dust and ambient temperature
