[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - Fan] trends: forecasting general ventilation fan from the main areas of demand structure (typically for small and medium centrifugal and axial flow fan) the most widely used HTFC row smoke wind chassis, the most in demand, manufacturers are up. Overall speaking, this kind of product oversupply. Special purpose fans (including anti-corrosion fan, heat fan, wear fan, exhaust fan fire, etc.) demand, while not great, but the special operating environment, require separate treatment, because the main material requirements more special. Roots blower is the most important feature within the allowable range when the pressure regulator, the flow rate has changed little, a wide pressure range of options, with forced gas transmission characteristics, the main drawback is noisy. [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - a roof fan] roof fan, roof fan base shall be installed above the roof surface should be smooth to prevent leakage of water seepage and shall be well embedded foot bolts. 2, padded base layer between the fan base and 5mm rubber sheet, to reduce vibration DWX wind chassis, anchor bolts should be fitted with a spring washer 9-19 fan parameters, prevent the use of loosening. 3, roof fan outlet diameter only larger, not smaller, the last outlet to install insect nets, tend to be increased when the rain cap on the wind; in case of winter snow, frost date, must often start, to prevent snow blower outlet blockage. 4, roof fan and duct using a hose (flexible material without burning) connection, the length of not less than 200mm, the same as the diameter of the roof fan and export size. To ensure the hose in the system during operation does not appear distorted, you should install the appropriate degree. For the suction side of the fan mounted on the roof of canvas hose, install a little more tight, to prevent the roof fan operation is drawn, reduce the size of the canvas hose section. 9-19 fan parameters, Langfang fans, Jinzhong Ji Tianjin Factory ventilation provided by the Tianjin Jinzhong Ji HVAC purification equipment.
