DDO 500
Direct Drive Motors are used for installations that do not require anti fall back devices. These are typically industrial roller doors and grilles, non-counter balanced and vertical lift doors.
The DDO motors 500 & 750 are equipped with a choice of mechanical or digital limits and a low-level haul chain to be used in the event of a power failure to open or close a door.
Both motors operate at 12rpm. DDO 500 has a 40mm bore while the DDO650 has a 55mm hollow bore..
