AC /Ec/DC175mm 190mm 220mm 225mm 220V Backward Centrifugal Blower Fan

Centrifugal Fan Product IntroductionThis series of centrifugal fans uses AC capacitors to operate asynchronous motors, which are divided into two categories: inner rotor and external transmitter. The fan has two modes of speed control, which is controlled by thyristor stepless speed regulation and motor winding tapping. The conventional three-speed adjustment Speed; The use of advanced technology to design the fan, with the advantages of convenient installation, reliable operation, low noise, large air volume, energy saving and high efficiency; using years of research and development technology of motor production, eliminate the AC electromagnetic noise generated during the operation of the motor, superior to similar products. ; Has the advantage of cheap high quality.Dear Sir/Madam,     Thank you for choosing Jinjiu in countless merchants and giving us the most precious thing in the world - trust. This makes us feel extremely warm and inspired, and we will do our best to make you feel comfortable and satisfied!Give Jin Jiu a chance, and we will be your best partner. I wish you good health, all the best, a happy life, and a smile!/* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
