Modern industrial production processes cannot do without vacuum technology. Aifiker vacuum systems help make the production process cleaner, smarter, more economical, and more environmentally friendly. We offer industrial users the most comprehensive range of vacuum pumps. Our pumps and accessories can be provided as individual components or as fully systematized, factory - tested combinations. The fundamental advantage of this system is that the compression chamber does not require working fluids such as oil. This eliminates all oil - related maintenance tasks, such as oil inspection, oil change, replacement of oil filters, as well as the costs of purchasing and disposing of oil and filters. The Mink claw - type vacuum pump also operates in a non - contact manner, which means that the parts in the compression chamber will not wear out due to mechanical contact. As a result, there are no wearing parts, and the related work and costs of replacement are saved. The non - contact operation of claw - type vacuum technology can also improve efficiency, and the required motor power is lower than that of traditional vacuum pumps. Two vacuum pumps equipped with standard motors are responsible for the basic load, and the other two vacuum pumps are frequency - controlled. By adjusting the speed, the vacuum demand can be precisely regulated. With this intelligent solution, the pumping speed of the central vacuum system can be accurately adjusted according to the current requirements. These control devices can significantly reduce the actual running time of each vacuum pump, because during normal operation, the four vacuum pumps do not need to run at full load. Therefore, the central vacuum system has sufficient power reserve to connect more packaging machines. In addition, we also plan to connect a vacuum filling machine for glass bottles. With it, the current decentralized liquid - ring vacuum pump equipped with a 7.5 - KW drive will no longer be needed, thus further saving energy. After more than two years of operation, the project manager is very optimistic about the future of this system based on the following: Energy demand has decreased by more than 70%. Maintenance work has been significantly reduced. Reliability has been improved. There have been no malfunctions or damages. The maintenance of the new central vacuum system is carried out by Aifiker's maintenance technicians. However, these maintenance tasks are limited to measuring the annual ultimate pressure and current consumption of each individual vacuum pump, as well as replacing the upstream particle filter and changing the oil in the gearbox.
