Axial fans are promoting the use of natural natural wind speed rotation of the turbine fan, and the indoor and outdoor air convection principle, parallel to the air flow in any direction, and into a bottom vertical acceleration of the air flow, in order to improve indoor ventilation change An apparatus for gas effect. The fan no electricity, no impatient tone, long-term operation. Based on air flow and air flow principles of natural law, is set at the top of the roof of rationalization can quickly exhaust gas indoor hot and dirty, improve the indoor environment. Is the use of natural wind turbine fan and indoor and outdoor temperature difference caused by air convection, rotation of the turbine and thus promote the use of centrifugal force and negative effects of the indoor stale hot air out. Axial fans a special energy efficiency, curved blades is the result of the best results of scientific computing, to strictly ensure working condition will never let rainwater intrusion. High efficiency exhaust ventilation without power much money, as long as not less than 0.2 meters in the breeze or indoor and outdoor temperature difference exceeds 0.5 ℃, can be lightweight, efficient operation. 2, the central axis has a fine level, so that the high-speed operation of the turbine blades never deformation, which greatly improves the fan's life. 3, variable angle neck design allows the fan installed in 0-22.5 degrees bevel under arbitrary. Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. Should consider installing roof ventilators wind areas, roof ventilators in the typhoon-prone areas and strong winds should be used with good anti-typhoon performance without power roof ventilation fan specifications, its center of gravity should be as low as possible to reduce the use of streamlined structure drag, wind rain umbrella hat performance very unsatisfactory, minimize the use of the structure. The advent of strong winds is non-normal conditions, rain hat design can stop the situation into account. Roof fan in the typhoon-prone areas and strong winds may also consider using the automatic installation of the aileron, even in strong winds, weather, due to the installation of automatic aileron will reduce a lot of wind and rain to enter. Ailerons will return to in situ by a spring mechanism, but also can play a role in reducing the aileron air resistance taped without power ventilators, roof ventilators achieve increased amount of wind effects. No power fan bearing temperature abnormally elevated main reasons can be attributed to improper installation, poor lubrication, cooling is not enough, bearing exception. Axial fan is to promote the use of nature's natural wind speed fan rotation of the turbine, and the use of indoor and outdoor air convection principle of centrifugal force without ventilation, the air flow in any direction parallel to speed and into the vertical air flow from the bottom up to improve indoor ventilation effect of a device. The fan no electricity, no impatient tone, long-term operation. Based on air flow and air flow principles of natural law, is set at the top of the roof of rationalization can quickly exhaust gas indoor hot and dirty, improve the indoor environment. No power ventilation specifications, Guangyuan no power ventilation, ventilation by Flextronics Flextronics Liaocheng ventilation equipment Limited. Liaocheng Flextronics Ventilation Equipment Co. (www.lcwctf.com) (www.lcwctf.com) strong, credible, Shandong Liaocheng fan, ventilation equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Flextronics ventilators and you hand into the brilliant, for a better future!
