High Capacity Ambient Air Barrier for Wide Industrial Door Openings

The Powrmatic BAR4/22A Baratherm Ambient Industrial Door Curtain is a high-capacity air barrier system engineered for large commercial and industrial doorways. Designed to create a powerful unheated air stream, the unit prevents uncontrolled air movement between internal and external environments, reducing heat loss and improving overall energy efficiency.

With an average outlet velocity of 15.3 m/s and high-speed airflow of 10,800m³/h, the BAR4/22A delivers strong environmental separation across wider openings. The system is optimised for mounting heights between 2.5m and 5.0m, making it particularly suitable for loading bays, distribution centres and high-traffic warehouse entrances.

The unit operates on a 230V~50Hz single-phase supply and incorporates four internal fans to ensure balanced airflow distribution across the full 2,250mm module length. By limiting cold air ingress, dust, fumes and insect penetration, the BAR4/22A supports improved comfort levels while helping reduce heating energy consumption when used alongside warm air systems.
