FUCARE Bubble-tight
Dampers are designed to provide the best tightness at extremely high pressure,
up to 20KPa differential
pressure by FC-RLD-LP 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 air filtering systems
of biotechnology labs, hardened shelters, control room of nuclear power plant,
control buildings of OGP industry.
