1. Wide range of applications: according to the different requirements of senior civil, use of variable speed or multi-speed drive form, the heart reached one machine (ie, when used through ventilation and fire temperature exhaust) purposes; leaf type into the shaft Streaming (HTF (GYF) -I, II) and Francis HTF (GYF) -IG, also making vertical rooftop exhaust fan fire, silencers style. 2. High efficiency: This series of axial fan using advanced CAD software designed and developed by the multi-objective optimization and development of new products exhaust fan control schematic diagram to show the measured efficiency of greater than 80% fan axial flow exhaust fan fire, some large machine number is greater than 85%, and has a flat efficiency curve characteristics are conducive to energy conservation; 3. easy installation, covering less than the centrifugal fan: The fan base in the form of axial fan or mixed flow fan, can be directly connected to the wind pipe or wall installation, the installation can be vertical or horizontal form. Largely saving footprint. 1.HTF-Ⅰ, HTF-Ⅱ, said pressure type fire temperature exhaust fan, leaf type with axial flow: HTF-Ⅰ (single speed) and HTF-Ⅱ (double speed) of two; HTF-Ⅲ, HTF -Ⅳ representation pressure fire temperature exhaust professionals; 2, HTF-X for silencer type fire temperature exhaust fan, the user can choose according to the actual needs of different kinds; 3, HTF-W Series rooftop fire temperature exhaust fan The user can choose according to the actual needs of flame-retardant fiberglass hood or steel hood; 4, HTF-D for low pressure type fire temperature exhaust fan; 5. Special note: GYF and HTF series fan is similar products. Roof exhaust fan | Yuzhou exhaust fan | Chenyu air conditioning services provided by Wu Cheng Chen-yu air-conditioning Limited.
