Robur Gas Air Barrier:
Industrial doors must be allowed to open and close as long as it is required to let people and transport in and out. This is sufficient to lower the internal temperature by several degrees and to increase the amount of time the heating system is running. In order to prevent heat loss, energy waste and subsequently to avoid thermal changes which can affect personnel and result in higher running costs, Robur has created the R4 Air Barrier which greatly reduces heat loss through the door openings.

The R4 operation is as simple as it is ingenious. It consists of a powerful fan, which can be set to operate each time the door is opened. It takes air from the upper area and blows it down over the door opening at high speeds through its long thin nozzle.

The installation of a Robur R4 air barrier is easy. The powerful centrifugal fan requires a single-phase (230V) electrical supply. The multi-positional wall fixing bracket allows for different nozzle angles to suit the characteristics of the door it is covering. By installing several R4 air barriers all door widths can be catered for. The R4 air barrier is fitted with a three speed regulator (fig.1) allowing the airflow duty to be altered depending on the units mounting height. The lower the door opening then the lower the airflow duty and thus, the lower the energy consumption.

For high doors the special Robur R4S air barrier has been developed: it has an higher air flow duty and thus a better airthrow which allows for a higher installation height (fig. 2 shows an installation up to 4.5 m high). In addition due to the special configuration, this R4S air barrier can be installed with an horizontal air throw for special applications.
