General Information

Compressed air (pneumatic energy) is as important an energy source for the production sector as electricity and hydraulics. Medium pressure air is a must, especially in the production of pet bottles, which are becoming increasingly widely used today, as well as sealing tests in pneumatic and hydraulic devices, and applications such as propulsion rollers, presses and fastening apparatus. Unlike other applications requiring compressed air, both low pressure and medium pressure air reaching 40 bar are used simultaneously in enterprises. Therefore, instead of designing the entire compressed air system according to medium pressure, it is the most appropriate solution to increase the air pressure only at the desired points of medium pressure.

Our DBK series booster compressors, which can increase the air in the range of 7-13 bar from the screw compressor in the product range up to 40 bar in different flow capacities, offer the most suitable solutions with years of experience and quality notion for pet bottle manufacturers and enterprises that need to use medium pressure air.

Iron cast cranks and cylinders, low-speed pistons, corrosion and heat resistant stainless steel valves, cylinders and top heads with cooling fins ensure the longevity of Yıldız Industrial DBK series medium pressure piston air compressors.

DBK series piston booster air compressors are manufactured to work successfully in different application areas. High performance and quality parts used in production and installation of products designed to be easily adapted and learnt by users at all levels provide long maintenance intervals and consequently low operating expenses.

  • It has high strength iron casting cartridges; oil level indicator positioned so that it is easily accessible on the crankcase, bluff valve, oil filling/discharge plugs and crankcase ventilation system.
  • Iron cast cylinders and top heads with cooling fins help the system operate at lower temperatures.
  • Dynamically balanced, produced through precise manufacturing processes and designed to comply with Lloyd type-approval certification, sphero casting crankshafts and counterweights provide a long service life.
  • Specially designed suction - force valves made of stainless steel are resistant to high operating temperatures as well as maximizing airflow.
  • Compression and oil rings are used to keep airflow to a maximum level and prevent oil passage.
  • High efficiency IE2 efficiency class IP55 engines are used as standard in DBK series air compressors.
  • The propulsion of the crankshaft is carried out by the belt-pulley mechanism selected according to a certain transfer rate between the compressor block and the main motor.
  • The belts are selected with a working life of 25,000 hours.
