Product description

PURPOSE
Specific speed value of SJG series ventilation fans is between centrifugal fan and axial flow fan, it has such characteristics as high pressure coefficient of centrifugal fan and high flow coefficient of axial flow fan as well as wide high efficient area.


Diagonal-flow fan, in addition to the unique air dynamic characteristic, of which structural type also makes engineering design and installation construction be simplified greatly, air inlet direction and outlet direction are located at same axistyle, inlet and outlet sizes are same and has flange connected to air pipe with same diameter, installation is very easy, it does not like centrifugal fan which should have a 900 turn, as a result less floor occupancy, without influence on pipe arrangement and running, mostly suitable for straight pipe pressurization and air pressure-feed and discharge systems, for machine house with small space, its advantage on compact structure is shown especially. 


SJG series diagonal-flow ventilation fans are widely used for ventilation and air conditioning of civil buildings and other industrial production fields to substitute LP centrifugal fan, saving investment and floor occupancy, simplified in design and convenient for installation. For such applications as the pressure of axial flow fan can not meet the pipe ventilation required, use of the diagonal-flow ventilation fan is the optimal selection.


SJG series diagonal-flow ventilation fan can feed air or other non-corrosive gas, air in which any stickum can not be contained, dust and hard grains contained can not exceed 150mg/m3. If explosion-proof motor and non-corrosive materials such as aluminum, plastic and  GFRP are used, it can feed inflammable, explosive or corrosive gas, but temperature of the gas to be fed can not exceed 80℃.


STRUCTURE
Diagonal-flow ventilation fan in comparison with centrifugal fan and axial flow fan has unique straight-line structure and air dynamic characteristic between both of them, basic structure and air flow status refer to the following figure and comparison of air dynamic characteristic graph refers to this manual.
