The NA-E-100 range of axial fans incorporates 10 models. The fans have been specifically designed to ventilate small rooms such as toilets, bathrooms and utility rooms and are ideal for wall, ceiling or panel installations. The units extract directly to the outside or through a short length of ducting, making installation quick and cost-effective. Used alone, the NA-E-100 fan will help reduce humidity levels in moisture-producing rooms, helping to maintain good indoor air quality in the home. It can also be used support a whole home Positive Input Ventilation (PIV) system such as the DRI-ECO-HC model where it is used to ventilate wet rooms not accessed from the central hallway or landing. This combination meets current building regulations.
