Product details

SR Grilles for Pipes are ventilation grilles made of stamped galvanized steel for direct installation in pipes, especially spiral pipes. The direction of the outflowing air can be adjusted using the horizontally or vertically arranged air blades. Due to its relatively large free cross-section, the hit and miss damper – which is fixed to the front frame and equipped with vertical links – optimally throttles the air flow. This also enables volume flow regulation and supports horizontal air stream deflection. Sufficiently uniform distribution of the outflowing supply air is ensured. The galvanized surface of the pipe grille is consistent with the pipe surface. Any required on-site finishing can be performed without difficulty.

Sizes (W x H): 425 mm x 75 mm to 825 mm x 225 mm (resp. 1025 mm x 125 mm)
