Atlas Copco Compressors has launched the QDT Activated Carbon Tower filter, designed to deliver the best air quality available from an oil-injected compressor.

This advanced filter system uses activated carbon to adsorb oil vapour from downstream compressed air to achieve and exceed Class 1 air purity, according to the ISO 8573-1 standard.

The Atlas Copco QDT Activated Carbon Tower filter offers a minimum lifetime of 4,000hrs within reference conditions of 35C ambient and a maximum air-pollution level of 0.35mg/m3 oil at the filter inlet.

The lower the inlet air temperature or the oil-pollution level, the more the lifetime of the Activated Carbon Tower will be extended.

Even where there is a high oil vapour concentration within a workplace environment, the QDT’s specific combination of volume and type of activated carbon adsorbs both oil mist and aerosols, and oil vapour, resulting in a guaranteed maximum downstream oil vapour content of 0.003mg/m3.

The QDT filter is capable of adsorbing an oil volume equivalent to 10 per cent of its own weight and the oil indicator provides an advance warning as to when the filter is fully saturated and needs replacing.

Combined with the easy maintenance procedure, this feature protects production processes and end products from the risk of further oil contamination.

The energy efficiency of the air net is also protected – the pressure drop penalty incurred is less than 0.3 bar.

Designed, manufactured and tested according to ISO 12500-2 standards; the only official standard for the reliability of compressed air filters, the QDT further extends the Atlas Copco particulate, water and oil-filter portfolio.

Atlas Copco offers oil-free and oil-injected compressors with filters and is able to advise on the compressor solution best suited for the individual application.
