The pipe system developed by Hailo with nominal diameters DN100 and Thanks to its plug connections, DN150 offers a comfortable solution for many ventilation applications in shaft constructions. The system is protected against aggressive media by the high-strength stainless steel 1.4404. Start component is the standard cap with cap. This is fixed with anti-theft screws and contains an insect-proof perforated plate. This can be removed for cleaning if necessary. Individual design is possible by different lengths of standard tubes and plug-in extensions, as are 90 ° bows. For mounting, displaceable flanges and wall brackets with different distances in the range of 50 - 200mm. The outer diameters are matched to those of KG pipes, so that a combination with them is possible without problems.
