CMT has developed into a single source vendor for air handling equipment across many industrial applications. Our capabilities allow complete fabrication, inspection, assembly and testing at one facility. Vibration and exposure to the elements can degrade equipment and affect bearings and structure. This tunnel fan is designed to provide fresh air and remove pollutants and smoke and provide mass quantities of air flow. Tunnel fans can be found in applications involving turnpikes, railways, subway tunnels and research labs.
