Air-handling parameters of NVH radial fans provide wide range adaptability. In average air-transmission the equipment can provide high pressure. They are excellent in air-delivery of industrial processes, in serving technological processes. Due to wide range utility, fans are manufactured with different technical solutions: from corrosion-proof steel to deliver hot and corrosive medium. When transmitting hot medium, they are manufactured with water-cooling or air-cooling. NVH type fans, with 0,09-16 m3/s air-transmission, are able to produce 230-9.500 Pa pressure increase in case of 1,2 kg/m3 clean atmospheric air. Fan efficiency - subject to operating point - is between 60 - 72 %. Fans are manufactured with bearing-bracket, block pulley armed with section steel-sheets.
