DUCON Activated Carbon Filters

DUCON Activated Carbon Filters

DUCON activated carbon filters use a dimensionally stable round design and can be safely integrated into dust extraction and ventilation systems. They remove harmful gaseous air pollutants effectively from industrial exhaust streams.

The activated carbon is selected and adapted according to the substances to be filtered. It adsorbs harmful gases, reduces odors, and cleans exhaust air. By using these filters, plants can minimize negative impacts on employees, the environment, and nearby residents.

Operating Principle

Raw gas enters the filter through the inlet manholes. The air to be cleaned is distributed evenly in the inlet chamber and then passes uniformly through the activated carbon bed. The carbon filling is held inside circular perforated sheet-metal cassettes.

As the gas passes through these cassettes, pollutants are adsorbed by the activated carbon; the cleaned gas is directed upward through the central tube. Activated carbon saturation progresses from the outside toward the inside over time. Once full saturation is reached, the carbon filling is replaced.

The clean gas is discharged through the stack installed at the top of the filter. To maintain optimum function and performance, pre-filtration is recommended before feeding raw gas into the activated carbon filter.

Technical Specifications

• Nominal air flow: 1,500-90,000 m³/h per filter unit
• Solids content: Solid matter in the gas stream should not exceed 5 mg/Nm³.

Equipment Features

• Robust construction with separate filling and discharge manholes
• Vertical ladder and access hatches suitable for easy maintenance operations
• Membrane-type explosion relief panels mounted on the body for pressure relief
