[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - Fan Fan] rely input mechanical energy, improve gas pressure side to send the gas turbine machinery without power, it is a fluid driven machinery. Exhaust pressure is lower than 1.5 × 10 Pa. Widely used in ventilation fan factories, mines, tunnels, cooling towers, vehicles, ships and buildings, dust and exhaust cooling, boiler and industrial furnace ventilation and the wind, the air-conditioning equipment and household appliances and cooling equipment ventilation, and sending grain drying, wind tunnel source and inflatable hovercraft and propulsion. Actual replacement of oil (or grease). Fans include fan, turbine blowers, blower and turbine compressors, including a detailed breakdown of centrifugal compressors, axial compressors, centrifugal blowers, blower, centrifugal fan, axial fan Yip blowers and 7 categories. [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product --DWT roof fans] a roof fan, roof fan base shall be installed above the roof surface should be smooth fan, to prevent leakage of water seepage boiler fans, and shall Well embedded anchor bolts. 2, padded base layer between the fan base and 5mm rubber sheet, to reduce vibration, anchor bolts should be fitted with spring washers to prevent loosening during use. 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 that the hose does not appear distorted fire exhaust fan in the system during operation, 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. _ Tianjin Jinzhong Ji wind chassis ventilation engineering (certified) _ Tianjin Tianjin Jinzhong Ji HVAC blower provided by purification equipment.
