Ningbo OULING OMJ-101A 2 Panel Center Opening VVVF Door Operator – Smooth, Precise, and Built for High Performance

The OMJ-101A is a center-opening elevator door operator designed for passenger lifts. It uses advanced VVVF (variable voltage variable frequency) control to ensure precise speed regulation and smooth acceleration. The result is quieter operation, better alignment, and longer component life.
