HTF (B) fire temperature exhaust fan Francis multi-objective optimization using CAD software design, matching molded cone twisted wing impeller, high temperature fully enclosed motor built, Francis fan stationed inside, arranged a special motor cooling system. Use two-speed motor direct-drive, Shijiazhuang Francis fan, to one machine (that usually send row when high-temperature exhaust ventilation and firefighting), arranged after the electrical control box can be remotely controlled automatically. High temperature performance, air volume, high pressure, easy installation, etc., are widely used in high-rise buildings, drying room, underground garage, subway tunnels and other occasions to send fire smoke and exhaust ventilation. Press GA211-1999 Fire fan high temperature test methods, can run at 400 ℃ high temperature continuous 100 minutes or more, Francis fan basement, medium temperature at 100 ℃ continuous operation 20 hours / time is not damaged, it has been the major cities nationwide fire departments authorized use. HL3-2A series of energy-saving low-noise mixed flow fan, is a new type of fan between axial and centrifugal fan between having a high pressure centrifugal fans, axial fans high-volume, high-efficiency, energy saving, low noise, convenient installation. This series of fan design, compact structure, small size, light weight, easy to install, compared with the old-fashioned centrifugal fans can save 20%, Francis fan laboratories, speed is less than 2000r / min, the noise is less than 75dB ( A), the fan is mounted on the connecting pipeline and air conditioning inside, noise is less than 70dB (A). Alternative 2000Pa below the low pressure centrifugal fan, widely used in industrial, civil ventilation and dust removal.
