Access Doors
The regular cleaning of ventilation ducts has become an undisputed necessity as it helps maintaining both the air quality and the efficiency of the distribution network.
The large number of dimensions as well as the various available versions of the METU access doors facilitate access to a large variety of ducts (simple, insulated high-temperature, double-wall, fire-rated, made of PVC, PE, PP or PPs). No Ex / ATEX certifications.
