SWF (HLF) series low-noise mixed flow ventilation fan

SWF series low-noise mixed flow ventilation fan

summary:
The SWF (HLF) series low-noise mixed flow ventilation fan is included in the national "Spark" plan project. It is an energy-saving ventilation equipment developed and promoted by the Shanghai Jiao Tong University Federation.

It is more reasonable for the current ventilation and air conditioning system to have a mismatch between the fan and the fan, which often results in high fan pressure but insufficient flow or high flow but insufficient pressure. This is beneficial for energy conservation in the system. It is currently the most suitable new product for pipeline pressurization systems in ventilation fans.purpose
：

Widely used in ventilation and air conditioning systems for industrial and civil buildings. Especially suitable for pressurized air supply in pipelines. SWF (HLF) - I type can replace high-pressure axial flow fan SWF (HLF) - II type dual speed, one machine dual-use, SWF (HLF) - III type can replace medium high pressure centrifugal fan.
structure and characteristics
：

The basic structural type is that the inlet and outlet are on the same axis (i.e. axial flow structure), the wheel shell is a conical cylinder, and the blades are of unequal width along the flow direction. There are three types of cylinder shapes: straight cylinder shape, drum shape, and imported curved muffler.
According to the principle of meridional acceleration of airflow, fans have dual characteristics of centrifugal and axial flow, which means they have both high pressure and large flow rate, as well as advantages such as high efficiency, low noise, and wide high-efficiency zone.

Compact structure, light weight, easy installation, and small footprint.
Installment and use


：


Horizontal, vertical, and suspended ceilings can be installed.

Ventilation, air supply, and pipeline pressurization can all be used.
