Each of the vacuum pumps from Gardner Denver Nash are driven by a motor equipped with a frequency converter, allowing the rotational speed to be set to exactly suit the actual process conditions. This causes the vacuum pressure to adapt to process conditions as well. Additionally, three centrifugal fans for the low-vacuum scavenge points in the forming section have been included. As a result, the vacuum system provides the greatest flexibility at optimum efficiency.

Features of the NASH 2BE3 vacuum pump include rotation speed control, low noise emissions due to the low peripheral speeds of the vacuum pump, future system adaptation, high operational safety, even if individual vacuum pumps are deactivated and low service and maintenance costs.
