The TNC cooling fan is meant for special cooling requirements. Designed for quiet and rapid heat dissipation, the TNC fan uses the TEK airfoil blower wheel to provide silent and efficient cooling, the company said. The TEK wheel is a molded, aerodynamically refined backward-curved impeller with non-overloading power characteristics. TNC cooling fans have high-pressure capability and are available in nine sizes that can produce airflows to 5,000 cfm. Custom mounting arms and special designs are available to accommodate most applications. The fans can be connected to independent control systems.
