Pipe grille for spiral ducts

SR pipe grilles are ventilation grilles punched from galvanized sheet steel for direct installation in pipes, in par-ticular in spiral ducts. The direction of the airflow outlet can be adjusted with the horizontally or vertically arranged air blades. The hit-and-miss damper, which is firmly connected to the front frame and equipped with vertical bars, optimally restricts the air flow with its relatively large, free cross-section; it also enables volume flow regulation and supports horizontal jet control. A sufficiently even distribution of outgoing supply air is ensured. The galvanized surface of the pipe grille is the same as the pipe surface, necessary on-site painting is not a problem.
