Ultimate Leakage Protection

Total Isolation Damper (TID)

To supplement our existing range of dampers, Wozair has added the new Total Isolation Damper (TID).

The TID is suited for extreme applications where there is a need to maintain zero 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.
