What is the SWSI Range?

The SWSI-SD-SDF range refers to a category of centrifugal fans known as Single Width Single Inlet fans. As the name suggests, these fans have a single width impeller and air enters through one inlet. At Sigrist Design, our SWSI fans are designed for applications that demand compact and efficient airflow solutions.

Differences Between SWSI and DWDI Fans

In contrast to DWDI (Double Width Double Inlet) fans, where air enters from both sides, SWSI fans are more compact. This makes them an ideal choice for applications where space is limited, such as in smaller ducts. At Sigrist Design, we specialize in providing fans that are adaptable to various environments without compromising on performance.

Types of SWSI Fans

At Sigrist Design, we offer various types of SWSI fans to suit different needs:

Forward Curved Blade Fans

These fans are known for moving a high volume of air at lower speeds. They’re typically used in ventilation systems where a gentle airflow is required, such as in office buildings or residential spaces.

Backward Curved Blade Fans

If you need a fan that handles high pressure with maximum efficiency, backward curved blade fans from Sigrist Design are an excellent choice. These are often used in industrial settings where airflow needs to travel long distances.

Radial Blade Fans

For handling heavy particulate-laden air, radial fans are ideal. At Sigrist Design, we offer radial blade fans that are built to withstand harsh industrial environments.
