Balanced Personnel Door – BPD

The Zacon Balanced Personnel Door utilizes the same patented "Balanced System" found in our larger Balanced Ventilation Doors. By dividing the door into two halves that swing in opposite directions, static air pressures and ramp slopes are disregarded.

The force exerted on one section of the door when opening against air pressure is counteracted by the opposing section moving with the air flow. As a result, our personnel doors can be effortlessly opened even in high-pressure environments.



  • The patented balanced system ignores static air pressure and ramp slopes.

  • From 0 to 9” W.C

  • Economical low power draw.  All components are designed for absolute minimal/no maintenance and upkeep.

  • Door systems are quick and easy to install.

  • Push buttons, pull cords, cap lamp sensors, remote control (in motion), motion sensors, and manual operation.

  • Custom programming.


Safety is paramount, which is why our doors are equipped with a self-closing operator as a standard feature. This ensures the door remains closed when not in use, and the closing force can be adjusted to meet your specific requirements.

To enhance safety further and prevent pinch areas, our Balanced Personnel Doors are accessible with a stretcher. The standard door clearance of 3 feet wide by 7 feet high, open to ground level, minimizes tripping hazards. Custom sizes are also available upon request, eliminating the need for squeezing through tight spaces.
