General Information

DVK series air compressors have been produced in order 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 in Turkey. With its after sales service network providing continuous service for more than 25 days and its customer support line which can be reached from all over Turkey from 444 in 2012, Products to be used safely.

  • New generation of screw blocks, designed with the benefit of the latest technology such as "Computational Fluid Dynamics (CFD)" and "Finite Element Method (FEM)" and manufactured with advanced manufacturing techniques, new rotor profile and lobe combination provide high efficiency, It offers consumption.
    There is a new generation of ball bearing tilt system with 3 times more load carrying capacity than standard designs.
    With the optimal lobe combination, the new rotor profile allows less air escape and reduces torque requirements, resulting in a significant reduction in energy costs.
    Gearboxes are used by American Gear Manufacturers Association (AGMA) standards.


  • High efficiency 380V / 3 phase / 50Hz IE2 IP55 motors are used as standard in DVK series.
    The driving of the screwdriver gearbox shaft is carried out directly between the screw block and the main motor via a flexible coupling with a 1: 1 transmission.
    Since there are no belt-transfer losses in the direct coupling system, it is up to 3% more efficient than the belt-pulley mechanism and there is no maintenance problem.
    By not using the belt-pulley mechanism, noise and vibration levels are noticeably reduced.
  • FEM and "Fluid Dynamics".
    The simple design of the suction regulator, which consists of three control block units, a solenoid valve and a control cylinder, ensures that periodic maintenance is easy.
    Suction regulator provides reliable working performance up to 8000 hours with the use of first class materials in manufacturing, reduced number of gaskets in design.
    The suction valve promises low pressure drops and high performance with a fully upright position, almost straight and unidirectional air flow, a new profile design and a 25% increase in air exit area when the suction valve is open.
    The two-stage air intake filter system, consisting of a replaceable microfiber glass front panel filter and cassette-type air inlet filter with interchangeable paper elements, minimizes problems that may occur in dusty environments by providing fresh air for the screw block and cooling system.
  • It achieves a more efficient decomposition at a lower volume with deep-bedded separating layers.
    It has a performance design that provides 3-step decomposition.
    After separation, a low oil solubility of 3 mg / m3 is obtained.
