Request selection

Provide the equipment type, airflow, static pressure, power, speed, supply and control requirements to help the engineering team begin motor selection.

The form uploads no data; it only prepares a local email draft. Until a separate export recipient is confirmed, overseas enquiries use the confirmed China contact.

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.

K-02Contact

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.
