FAQ

Whatever the duct system requires — it is not a free choice. ROTER's published range runs from 100 Pa on the 200–1,000 m³/h fresh air ventilators up to 400 Pa on the larger ceiling-mounted units and 460 Pa on the vertical series. The long-range jet unit is the exception at 0 Pa, because it discharges a high-velocity jet rather than pressurised duct air.
