Side Channel Blower

What is a Side Channel Blower?

Side channel blowers are known for their reliability, versatility, and cost efficiency, making them ideal for a broad spectrum of industrial applications.

One prominent use is in fume extraction, as well as cooling and drying processes in industries ranging from manufacturing to food processing. Their ability to generate uniform airflow also makes them suitable for driving air knives, which are used to remove liquids or debris from products.

In waste recycling, side channel blowers can separate lighter materials from heavier ones by blowing them into separate process lines. In water treatment plants, they aerate water by supplying air through membrane diffusers, ensuring efficient oxygen transfer. This same principle is applied in chemical engineering and even laboratory-scale experiments.

Another common application is pneumatic conveying, where compressed air generated by the blower transports lightweight granular materials, such as plastic pellets or polystyrene beads, through pipes. Side channel blowers can also move small cylindrical containers or facilitate processes like air table conveyors, where lightweight products are carried on a cushion of air.

For vacuum applications, side channel blowers excel in tasks such as vacuum holding on CNC machines or vacuum lifting systems. For example, they securely hold workpieces in place during cutting operations, eliminating the need for mechanical clamps.

Why Choose Side Channel Blowers from Fans and Blowers?

Side channel blowers from Fans and Blowers are available in a wide range of sizes, from 50 m³/h to 3,000 m³/h, with differential pressures up to 1 bar. They are manufactured using high-pressure die casting, resulting in a lightweight yet durable product. Custom solutions are also available, such as special motor voltages, internal coatings, and surface treatments to suit specific requirements.

For energy efficiency, side channel blowers can be paired with variable speed drives (VSDs), allowing precise control of airflow and reducing power consumption during idle periods. Additionally, they are well-suited for use in potentially explosive atmospheres, with ATEX-rated options available for zones 21 and 22, as well as for handling biogas and industrial gases.

Another advantage is their quiet operation, made possible by integrated silencers. This feature makes them an excellent choice for noise-sensitive environments. Moreover, two-stage and three-stage side channel blowers are available for applications requiring higher pressure or greater compression.
