General Information

Compressed air (pneumatic energy) for the manufacturing sector is as important an energy source as electricity and hydraulics. Especially in the production of pet bottles which are becoming increasingly widespread nowadays, high pressure air is a necessity in applications such as drive cylinders, presses and fixing apparatuses, in sealing tests in pneumatic and hydraulic devices. Unlike other applications where pressure air is required, in these applications both low pressure and high pressure air reaching 40 bar are used at the same time in enterprises. Therefore, instead of designing the whole pressurized air system according to the high pressure, it is the most suitable solution to increase the air pressure only at high pressure points.
DALGAKIRAN, which has DBK series booster compressor models that can extract air from 7-13 bar range from screw compressor up to 40 bar at different flow capacities, offers the most suitable solutions with years of experience and quality understanding for pet bottle producers and enterprises that need to use high pressure air.

Cast iron castors and cylinders, pistons operated at low speed, corrosion and heat resistant stainless steel valves, cooling finned cylinders and top heads, DALGAKIRAN DBK series ensure long life of high pressure piston air compressors.

The DBK series piston booster air compressors have been produced to work successfully in different application areas. High performance and quality parts used in the manufacture and assembly of products designed to be easily adaptable and user-friendly at every level provide long maintenance intervals and consequently low operating costs.

DALGAKIRAN operates in more than 100 countries worldwide and has more than 150 authorized dealers throughout Turkey. With its after sales service network, which provides continuous service for more than 25 days, and customer support hotline from 444 in 2012 Customers to use their products in confidence.


  • Cast iron casters with high strength; A bluff valve, oil fill / drain plugs, and a sump ventilation system, all of which are conveniently located on the sump.
    Cooling finned cast iron cylinders and top heads help the system operate at lower temperatures.
    Ductile cast iron crankshafts and counterweights designed for dynamic stability, precision manufacturing processes and designed for Lloyd type-approval certification ensure long service life.
    High pressure resistant, specially designed suction and discharge valves made of stainless steel are able to withstand high operating temperatures as well as keeping airflow at maximum level.
    Compression and oil rings help to keep the airflow at maximum level and prevent oil passage.
  • High efficiency IE2 efficiency class IP55 motors are used as standard in DBK series air compressors.
    The drive of the crankshaft is effected by a belt-pulley mechanism selected according to a certain transmission ratio between the compressor block and the main motor.
    The belts were selected for a working life of 25,000 hours.
    Specially designed fan-type cast iron pulleys dampen vibrations in the body by functioning as a flywheel as well as providing high volume airflow to cool the compressor block.
    Easy adjustable belt tension ensures efficient operation of the compressor at all times.
    The special unloading system extends the life of the electric motor and the compressor block.
