The 2200 Series are substantial-overall performance, minimal-leakage Regulate dampers designed with a thermally broken concept to minimize thermal transfer and decrease condensation. The 2200TB model functions thermally broken blades, although the 2200TBF model contains equally thermally broken blades and frame for Increased Electrical power performance. 1210SS Collection dampers are ... https://heavydutystainlesssteelda00112.digitollblog.com/36870197/dampers-for-industrial-sector-no-further-a-mystery
