RKALM 1000x500 .01

RKALM aluminium regulating dampers are designed for air without abrasive, chemical and adhesive impurities. The RKALM four-sided dampers are designed for environments protected against weather conditions with the 3K5 classification of climatic conditions, without condensation, icing, ice formation, without water even from sources other than rain and with a temperature limit of -15 to 80 °C. The damper frame and blades are made of aluminium EN AW 6060 T6, the blade pins are plastic, the control pins are made of galvanized steel. The gears are made of polypropylene. Depending on the internal components used, the required technical characteristics of the dampers can be achieved. The maximum air flow speed is 8 m/s. The maximum overpressure on the damper is 1200 Pa.

VARIANTS
