This 8-inch to 12-inch Vano Expo-Proof Fan has a high-performance, strong, and long-lasting design, making them suitable for process vessels, ventilating tanks, tank cars, manholes and other narrow areas. They provide superior static pressure due to the straightening vanes. Ducting is accepted both on inlet as well as outlet ends. They are available with explosion-proof (EP) or totally enclosed (TE) motors and compatible switch. A 15-foot power cord is supplied with all single-phase models. The ventilators are made of heavy-gauge, powder-coated steel and cast aluminum. The fan blades are spark-resistant.
