Product Overview
Although the Building Code of New Zealand sets out minimum ventilation requirement for industrial and commercial premises, this can be less than adequate according to the building use. It is generally recognised that workplace efficiency is improved when ventilation matches the interior conditions. Extracting oppressively hot air and fumes minimises worker lethargy, loss of concentration, and consequent loss of productivity. Even in colder weather, effective air circulation improves the workplace environment, so your investment works all year.
Install Ampelair turbo ventilators and you'll probably retire before they do. They are very well engineered and constructed requiring very little maintenance even after years of service. A feature of the 500 and 600 are their low profile design and aluminium construction. There is a two part shaft system comprising of an anti corrosive steel axle fully sealed in a fire resistant nylon casing. Ampelair ventilators are designed to give optimum efficiency through the angle of the vane and the enlarged surface area. Even in cross winds the wave shape will retain its rotational strength. |
