Mine Ventilation
Design and maintenance of ventilation systems for mining operations.
Metal-Air is committed to the design, development, fabrication, and installation of high-performance steel ventilation ducting products for underground mining and tunneling, and industrial applications. Our combination of expertise, experience and commitment is demonstrated through our ventilation products and our services to the underground world. We understand that underground mine ventilation is an extremely important area of focus for all mining professionals as mines must be adequately ventilated to ensure a cleaner and safer workplace.
Metal-Air can provide all mine sites with the fast and reliable production of heavy duty manufactured spiral steel ducts, of any length, any size, and any diameter. It is durable enough to sustain any normal mining conditions. Ducts are easily connected using flanges and v-locks, or simply made with a plain end connected by a 12” wide drawband. Either way, the installation in your typical mining ramps and headings is quick, effective, and straightforward. Ducts can be manufactured at the underground site which saves time therefore reduces cost.
