ROBUR R4S - Воздушная завеса

The R4S air barrier is used in factories or workshops where frequently opened doors cause cold air to enter, thereby lowering the internal temperature and increasing heat loss.‎ The air barrier R4S, with increased fan-size and pressure head, is supplied as standard with a speed fan.‎ Advantages - One barrier, two advantages.‎ The R4S 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.‎ This action promotes two fundamental effects.‎ It helps to eliminate heated internal air from escaping to outside and also re-uses the hotter air from the higher area by blowing it back down to the lower working level where it is needed.‎ - Simple installation – maximum versatility.‎ The installation of a R4S Robur air barrier is easy.‎ The powerful centrifugal fan requires a single-phase (230 V) electrical supply.‎ The multipositional wall-fixing bracket allows for different nozzle angles to suit the characteristics of the door it is covering.‎ By installing several R4S air barriers all door widths can be catered for.‎ The R4S air barrier is fitted with a speed regulator 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.‎ The Classic range has marked the evolution of heating, a historical line par excellence, which has become synonymous with hot air generators fuelled by natural gas and LPG and a wide range of solutions to meet the heating and cooling needs of environments.‎ A complete range of hot air generators, combined boiler and unit heater systems, destratifiers, coolers, radiators and air curtains, ideal for heating and cooling industrial, public and commercial buildings.‎ Further info from manufacturer on R4S ROBUR
