The company has recently added the GBH-8 to its range of side channel blowers designed for use in wastewater purification applications and in the oxygenation of activated sludge tanks. Compared to a standard blower of similar output, the new GBH-8 is 65% lighter, has a 40% smaller footprint, and offers twice the power. Using techniques such as CFD (computational fluid dynamics), the GBH-8 also offers high performance, with a continuous build-up of pressure. The unit features rotational speed control for easy setting of the optimal operating point, with pulsation free air supply and low noise levels. In addition, bearing lifetime in the GBH-8 is 20,000 hours, meaning downtime for maintenance, and the associated costs, are kept to a minimum.
