On May 11, 2026, LONGWELL opened a request for industrial air curtains LWAC-BG4510S-01 and LWAC-BG4515S-01. The customer requested pricing for nine units of each model.
Door-switch requirement and project limit
The customer later requested a magnetic door switch. The project record states that the requested addition could not be supported because of the units’ high power. This is the constraint recorded for these configurations; it is not a general claim that magnetic door control is impossible for every industrial air curtain.
The technical-review milestone was completed on May 12, 2026. The case documents a configuration assessment and its limitation, rather than an implemented door-switch solution.
