On July 18, 2026, LONGWELL opened a request to review a customer-supplied metal axial impeller sample. The customer specified an eight-blade impeller and said the previous drawing did not match the sample.

Requested drawing correction and tooling assessment
The requested sequence was clear: prepare a matching drawing from the physical sample, then assess the tooling cost, minimum order quantity and unit price for the resulting design. The source photograph shows the reference impeller and its surrounding frame.
The project record includes model-assignment and packaging milestones dated July 25, 2026. It does not include a completed technical drawing or a finished technical-review milestone for this request. The recorded case therefore remains a sample-based drawing and tooling evaluation, without a claim that corrected tooling or a matching production impeller was delivered.

Discuss a similar requirement
Send clear sample photographs, blade count, impeller and shaft dimensions, rotation direction, operating speed and expected order volume through the LONGWELL contact page. These details define what must be matched before drawing and tooling work can be evaluated.
Choose the right fan impeller
Longwell manufactures 10 fan impellers in-house. Send airflow, static pressure and voltage — an engineer replies with a matching model, performance curve and price within one working day.
