Continental Industrie Centrifugal Blowers and Vacuum Cleaners are rotating machines used to increase the pressure of a gas, ambient air or a gas mixture, through centrifugal force transmitted by an electric motor. The performance of the machine is directly related to the following characteristics: flow rate, differential pressure and electrical consumption. One of the main advantages of our machine is the non-existent friction between the rotor and the body, in the same way that the shaft only has two points of contact, the bearings. For this reason the estimated life of our machine can exceed 40 years. The performance of the machine can be affected by external factors, such as the accumulation of deposits at the filter inlet, a problem that can be solved by following the correct maintenance instructions. It can also be altered by the variation in the weight of the molecules of the treated gas, or, for example, the variation in temperature or the intake pressure of the machine.
