Induction fan motor can provide voltage: 200-240V; Frequency: 50 / 60Hz; motor speed according to user requirements into a single-speed, two-speed, three-speed; sales of high-end output power induction fan, fan motor may be provided by inducing households . 2, and the frequency with ordinary wall-mounted air conditioner outdoor unit supporting the use of a fan. 3, the motor is "NSK" Rolling bearing low noise high quality induced fan design life million hours. 4, the shaft after quenching and nickel alloys, high-tensile steel chassis and by using rustproof galvanized treatment. 5, high electrical efficiency, low noise induced fan, little vibration. Induced dedicated fan volute "dual spin mute volute" technology, and a unique "CPS without resistance guiding principle, resorted wind smoother, more powerful suction fan model induction, lower noise. Is the world's most advanced The air jet fan replacement system is a special axial fans, mainly for longitudinal ventilation system of highways, railways and subway tunnels, and provide all of thrust; can also be used for semi-transverse ventilation system or transverse ventilation system sensitive parts, such as the tunnel inlet and outlet, or smoke from the induced flow effects. Jet Fan is an open inlet and outlet of special axial fans, in this condition the fan is designed to work with the highest efficiency (greater than running operating point with a certain static pressure) air force jet fans, that is commonly referred to - thrust, and fan support by force "and other large, inverted" fan model _ induction Rainbird environment (already certified. ) _ Fan Co. Linyi induced by Wu County Rainbird environmental engineering. Wu County Rainbird Environmental Engineering Co., Ltd.
