Retailers and museums hide these in their primary entrances to create a thick wall of air that conserves energy and assists with climate control when the flow of foot traffic means that the door never closes.

To work with Berner Engineering on your entrance, contact either your Berner representative or Berner directly – 800-245-4455.


Energy Efficient

Used by popular retailers for entrances with non-stop foot traffic to keep conditioned indoor air separate from outdoor air, which helps keep energy costs low and recaptures as much as 90% of circulated air.

Integrates into the Entrance
  • Designed to both meet the functional needs of the application and to integrate into the architectural design of the space
  • Provides a recirculating air seal, through concealed ductwork
  • Typically installed as part of the build-out of the entrance
Automatic Cleaning

The system filters dirt and foreign particles out of the recirculating air, and the filters are then cleaned by an automatic wash system.

Reliable Operation

This is a whole new level of safety, performance and comfort — built on a 60-year tradition of excellence.
