Fan heater by the use of materials can be divided into several classification, such as steel fans (ordinary fan), FRP fan, plastic fan, aluminum fan, stainless steel fan, etc. 2 warm. Fan classified according to the direction of gas flow can be divided into centrifugal , axial, mixed flow (Francis) and cross-flow and other types. 3. Warm the fan according to the flow direction of the airflow into the impeller into: axial fans, centrifugal fans and mixed flow (Francis) fan. 4. Fan heater use is divided into the push-local fan (hereinafter referred to as the push-fan) and explosion-proof electric motor placed runner outside or in the flow path, explosion-proof electric motor placed in the sealed chamber withdrawable local fans (hereinafter referred to as Exhaust Fan). 5. The fan heater in the form of a pressurized can also divide a single-stage, two-stage or multi-stage pressure fan. Such as 4-72 single-stage pressurized, high Refine machine is a multi-stage pressure fan 6 warm air blower can be divided according to use divided: axial fan, Francis fan, roof fans, air-conditioning fan and so on. 7. Press the pressure blower fan performance parameters can be divided into low-pressure fan pressure fan, high pressure fan. Fan performance parameters of fan heaters are mainly flow, pressure, power, efficiency and speed. In addition, the noise and the size of the vibration is also a major fan design specifications. Also called air volume flow to flow through the fan indicates the volume of gas per unit of time; pressure, also known as pressure, refers to the value of the gas pressure rise in the fan, there is static, dynamic pressure and total pressure points; power is the fan input power, namely shaft power. Fans effective power and shaft power ratio is called efficiency. Fan total pressure efficiency up to 90%.
