Rectangular air damper TID

The Total Isolation Damper (TID) is suited for extreme applications where there is a need to maintain ultra tight leakage rates while operating within high ductwork pressures. It is designed in accordance with BNG/BNFL and AWE specification NF0155/1 and DSD/A/S/2051/001. The TID also meets BNFL/BNG ductwork specification NF0154/3. In order to achieve this, a unique blade design has been developed in line with NF0155/1 and DSD1/A/S/2051/001.
