The Dor-O-Matic 2900 Series Compact Automatic Sliding Door Operator combines understated elegance with robust functionality.  The innovative design brings together a slimline modular system for accurate installation with advanced componentry to provide enhanced control of the operating modes.

The operator is a self contained electro-mechanical drive unit for surface applied applications on new or replacement doors.

With an overall height of just 10.5cm and depth of 13cm the 2900 series is designed to aesthetically fit onto existing profiles.

The 2900 Series installation process facilitates fast and accurate assembly of an automatic door operator using an integrated modular interlocking system.




  Features of the 2900 Series include:

  • Drive components assembled onto the chassis which easily fits into the main body extrusion.
  • Maintenance free self contained motor gear box drive unit with positional encoder.
  • Robust secure slide fit cover clip which allows easy access for routine maintenance and repair.
  • Self monitoring battery pack to drive the door to the open/closed position in the event of power failure.
  • Microprocessor controlling the positional sense of the door at all times and controls the operation of the door following the settings from the user interface (UI).
  • Kevlar material drive belt that gives low friction and high resistance to wear and tear.
  • Switched mode Power Supply Unit (PSU) which transforms, rectifies and regulates the supply voltage of 240 volts to 24 volts DC. Intrinsic within the PSU is a thermal and current overload protection with automatic reset.

High density rollers ensure smooth and quiet operation utilising an anti riser roller to prevent perpendicular movement.
