On June 27, 2026, LONGWELL opened an engineering project to develop a dual-speed AC cross flow fan specification under part number LWCA-110820SN-06-12. The customer requested a low-speed option based on the 110820 frame platform to establish a noticeable distinction in air volume for film set wind effect applications.
