The GEF CA & DCA units are compact and efficient units for the effective extraction and filtration of fumes for many applications. This series uses carbon filter media to absorb any contaminant fume and the thin layer structure of the cylindrical filters allows the fume to have a quicker contact time with the carbon particles. The CA & DCA filter units are supplied with three stage filtration as standard:

  1. First stage of filtration using a polyester or paint stop filter 
  2. Second stage for finer filtration using a synthetic filter
  3. Final stage utilising the thin layer of activated carbon cartridges for efficient fume absorption

The DCA unit is designed with a built in fan in an acoustic sound proofed enclosure and each unit is supplied with an inspection panel.

AES can supply the CA & DCA units in a number of custom finished including materials and painting options.


  • Ceramic
  • Food Industry
  • Painting & Solvents
  • Plastic Dust

Product Details

The activated carbon filter series from GEF use thin bed cartridge filters, which do not compromise in performance and maintain the characteristics and dwell time of a standard carbon filter.

The CA & DCA come in a wide range of configurations, ranging from 2 to 16 activated carbon filter cartridges, and can handle airflows up to 12,000 m³/h. Having this unique three stage process of filtration allows the CA and DCA to provide good performance whilst keeping a compact profile.


  • Carbon filter media weight from 28 to 224 Kg
  • Inlet fan from 1.1kW (also single phase) to 7,5 kW (DCA series only)
  • Structure made with aluminium profile (size 20 excluded)
  • Max. vacuum 1800 Pa
  • Max. temperature 60°C.


• Electrical panel for the fan (DCA Series)
• Electrical panel with inverter for low energy consumption and performance control
• Spark arrestor

The DCA series come fitted with a suitable built in fan, ranging from 1.1kW to 7.5kW in power, giving the unit efficient airflow and extraction of the contaminant fume, combined with the triple stage filtration ensures effective filtration and a safer working environment.
