On July 22, 2026, LONGWELL opened an engineering project to update an existing cross flow fan configuration. The revised requirement specified a 48V DC operating voltage with an updated nominal speed of 2900 RPM. In response, LONGWELL engineering reviewed the configuration and prepared the revised technical drawing and specification under model number LWCD-45190HN-07-00 on July 23, 2026.
