The basic design concept for all LCN power operator systems is door control of both the opening and closing motion of the door. Our designs allow the system to be easily retrofitted into existing doors and frames as well as new construction. A basic LCN electrohydraulic/pneumatic system consists of a power operator based on a heavy duty LCN 4040 Series door closer and peripheral actuators. Our electromechanical automatic operators utilize a motor gearbox and a control box to perform the opening and closing function. LCN offers a choice of either electrohydraulic, electromechanical or pneumatic low energy automatic operators.

The 4810 Auto Equalizer™ is LCN’s pneumatically powered MULTIDOOR solution. This low-energy automatic operator provides easy access for people with disabilities, or the elderly. Designed primarily for manual opening applications that occasionally require automatic opening.

  • Multi-Door Solution
  • Utilizes a 10,000,000 Cycle Heavy Duty Door Closer
  • Quiet, Efficient & Reliable
  • Requires ACC Controller using auxiliary air supply (compressor) - See example ACC1
  • Safety Products - Dictated by traffic profile
  • All Weather Fluid - Performs without variation:
        Manual Closers - between -35° to +49°C
        Electronic HO Closers & Automatic Operators - between +2° to +49°C
        At approx. +75°C the fluid will begin to leak from the mechanism. The flash point is approx. 110°C
