Overview

Using centrifugal separation technology, Donaldson’s industrial separators remove water, oil aerosols, and solids from compressed air streams with minimal pressure drop. Their robust, corrosion-resistant design supports flow rates from 119 to 11,000 m³/h (70 to 6,470 scfm).

Inside, swirling vanes or cyclone inserts generate centrifugal motion to separate contaminants, which are discharged via time-controlled or zero-loss electronic condensate drains. These centrifugal separation equipment units operate without disposable filter elements, supporting low cost and service time in industrial compressed air systems.

 

DF-C Series – Compact Centrifugal Separators for Efficient Moisture and Particle Removal

The DF-C Series is a compact cyclone separator designed for efficient centrifugal extraction of water and solids in smaller systems. Its specially engineered cyclone head insert creates strong rotational flow to separate moisture and particulates from the compressed air stream.

 

Main Features & Specifications

  • Cyclone head insert enables effective centrifugal separation
  • Filterless operation for low maintenance
  • Bayonet lock prevents opening under pressure
  • Immersion-lacquered housing for Dual-layer corrosion protection
  • Flexible installation - Wall bracket and UFM-D drain options available
  • Flow range: 119 to 1,099 m³/h (70 to 647 scfm) at 7 bar(g)

Application

  • Moisture and coarse particle removal in compressed air lines
  • Pre-filtration for dryers and downstream filters
  • Ideal for compact to mid-sized systems requiring centrifugal solids separators or solid liquid separation equipment

 

SG-C Series – High-Capacity Centrifugal Separators for Large Industrial Systems

The SG-C Series is a robust industrial separator designed for high-volume systems. Its integrated swirl vane system supports consistent centrifugal solid liquid separation, while the durable carbon steel housing and service-friendly options make it ideal for demanding applications.

 

Main Features & Specifications

  • Designed for low pressure drop across high airflows
  • Integrated swirl vane for contaminant separation efficiency
  • Extra baffle plate for low aerosol carryover
  • Epoxy-coated carbon steel housing, designed for long-term use
  • Electronic drain and ball valve options
  • Flow range: 1,650 to 11,000 m³/h (971 to 6,470 scfm) at 7 bar(g)

Application

  • Centralized air treatment in high-flow industrial systems
  • Pre-treatment for dryers and sensitive downstream equipment
  • Ideal for users seeking centrifugal separation equipment, industrial centrifuges, or low-maintenance moisture separation solutions
