FC-RLD-HP Heavy-duty Plus Bubble-tight(Zero leakage) Air Tight Dampers

FC-RLD-HP Bubble-tight Air Tight Dampers are designed to provide high level tightness at extremely high pressure, up to 100KPa differential pressure and can stand pressure difference up to 180KPa without permanent deformation which may affect its tightness performance. Therefore, this product is capable to tackle the most critical situations for key buildings or systems such as NBC filtering system of hardened shelters, control room of nuclear power plant and control buildings of OGP industry.
