Large volumes of compressed air and vacuum are required in the manufacturing process of hollow glassware. High quality and reliability of all units and components is of prime importance, because equipment failure during production invariably means extremely high costs. For continuous 24-hour operation, rotary vane compressors and vacuum pumps offer the best solution.Compressed air is used to form the blanks in the production machines. A compressed air system is needed to control the various shaping devices and the general air supply of the factory.
Rotary vane vacuum pumps are used to evacuate the glass moulds. This ensures high product quality and increasing the number of pieces per hour poses no problem.For higher volumes vacuum pump stands are used. These two-stage systems consist of a rotary lobe and rotary vane vacuum pump and are used in the production of electric light bulbs and fluorescent tubes.Related Products: Systems
