DIDW Blower
DIDW Centrifugal Fans are fans that are double the width of a conventional fan, they are essentially 2 fan sets back to back with the adjoining case wall removed. This has the advantage of a smaller overall footprint and only one motor is required.
The performance is quite simple: a DIDW Fan gives the same pressure rise but double the flow of a single inlet single width (SISW) fan.
DIDW fans are conventionally used in heating and ventilation however Halifax Fan uses the DIDW's generic design; couple it with our build quality and offer heavy duty industrial versions. These can be used in many applications where a large volume of air is required against a low to medium pressure.
