DBK Series Overview

The DBK series of reciprocating booster air compressors is designed for high pressure applications. These compressors can increase the pressure of the air entering the compressor from 7-13 bar up to 40 bars, making them ideal for a range of industries, including pet bottle manufacturing.

 Features

• Standard Equipment:

  • High-quality components such as IP55 electric motors with the IE3 efficiency class.
  • Star-delta motor starter system.
  • Electrical materials that are compliant with IEC, UL/cUL, and CE standards.
  • Durable compressor blocks, designed to meet various market requirements.

• Reliability:

  • FSCurtis compressors pressurize the air from 7-13 bar up to 40 bars using DBK series booster compressors.
  • Widely used by pet bottle manufacturers and other industries, and proven reliable in many applications.
