A-250-QS Double Inlet Centrifugal Blowers And Fans
A series centrifugal fans that we research and develop absorbed advanced technology from home and
abroad. All the components of this series fans are all mold-produced, so the fans are compact structure .
reliable operation. large air volume and quiet, also with high efficiency and low-noise, while still easy to
install and debug. SJX series cabinet air-conditioning blower research and develop is based on our historical
forward curved multi-blades centrifugal fans. This kind of blowers fully conforms to A series on
performance. Its structure was patented, which makes the surface smooth and artistic, and satisfies
customers' visual aesthetic better.
The fans are widely used for air conditioning. purification. telecom. ventilation and other areas.
(1)The parameters listed in this catalogue were tested under standard condition.(Gas density is 1.2kg/m
temperature is 20°C)
(2)The gas transported by the fans should be non-corrosive, non-flammable, non-explosive and non- sticky.
(3) Operating conditions: the ambient temperature range should be: 40°C --- +60°C ,the relative humidity
should be less than 90%, the altitude should be less than 1000 meters .
(4)The centrifugal fans are divided into levorotation and dextrorotation. For single inlet centrifugal fan, face
the air inlet side. For double inlet centrifugal fan, face the wire outlet side, if the impeller rotates clockwise,
we call it dextrorotaion. Otherwise, it's levortation. If the fan is equipped with support, then there are three
kinds of air direction: 0, 90,180
(5)You can select the A series centrifugal fan model according to the catalogue so that we can customize
the corresponding cabinet air-conditioning blower per your needs.
(6)There is no support for forward curved multi-blades centrifugal fan from 133mm-250mm. Other models
have the support. And there is no current collector for backward curved impeller centrifugal fan. You need
note if you want the support or current collector for fan model, clarify the fan model. specification、 air
volume and static pressure before placing an order. For forward curved multi-blades centrifugal fan and
backward curved impeller centrifugal fan, you need to note the air direction. (See blow)
