It is used after suitable prefiltration when residual oil vapors and hydrocarbon vapors need to be reduced further in addition to solid particles and aerosols.

Liquid oil and ultrafine aerosols are first reduced by suitable separation and coalescing filters. Gaseous oil and hydrocarbon vapors, however, cannot be captured to the same extent by these filtration stages. This is where the activated carbon in the DFF-A is used.\u003c\/p\u003e\u003cp\u003eThe DFF-A adsorbs residual gaseous oil components and odorous substances. Under the specified operating conditions, this can reduce the total oil content of the compressed air to \u003cstrong\u003e\u0026lt; 0.005 mg\/m³ at 20 °C\u003c\/strong\u003e. This value assumes suitable upstream compressed-air treatment.\u003c\/p\u003e\u003ch5\u003eWhy Prefiltration Is Necessary\u003c\/h5\u003e\u003cp\u003eActivated carbon should be exposed to as little liquid condensate, coarse particulate contamination and high aerosol loading as possible. These contaminants consume adsorption capacity unnecessarily and shorten the service life of the filter element. The DFF-A is therefore typically installed downstream of suitable prefilters and fine\/coalescing filters.\u003c\/p\u003e\u003cp\u003eWithin the DFF series, for example, \u003cstrong\u003eDFF-P\u003c\/strong\u003e filters can be used for coarse filtration, \u003cstrong\u003eDFF-M\u003c\/strong\u003e filters for microfiltration and \u003cstrong\u003eDFF-S\u003c\/strong\u003e filters for very fine separation of particles and aerosols. The required combination depends on the inlet-air quality and the compressed-air quality to be achieved.\u003c\/p\u003e\u003ch5\u003eTechnical Specifications and Selection\u003c\/h5\u003e\u003cp\u003e\u003cstrong\u003eFilter principle:\u003c\/strong\u003e Activated-carbon adsorption\u003cbr\u003e\u003cstrong\u003eMaximum residual total oil content at 20 °C:\u003c\/strong\u003e \u0026lt; 0.005 mg\/m³\u003cbr\u003e\u003cstrong\u003eMaximum operating temperature:\u003c\/strong\u003e 45 °C\u003cbr\u003e\u003cstrong\u003eMaximum operating pressure:\u003c\/strong\u003e 16 bar\u003cbr\u003e\u003cstrong\u003eFlow rate at 7 bar:\u003c\/strong\u003e 1.2 to 36.0 m³\/min, depending on model size\u003cbr\u003e\u003cstrong\u003eFilter element:\u003c\/strong\u003e Replacement interval according to operating conditions and product specifications. The activated-carbon stage generally requires a shorter replacement interval than pure particle filtration stages.\u003c\/p\u003e\u003cp\u003eThe actual flow rate under the existing operating conditions is decisive when selecting the correct size. Pressure, temperature and inlet-air contamination affect treatment performance. The filter should therefore be sized not only by connection size, but also by flow rate and the required compressed-air quality.\u003c\/p\u003e\u003ch5\u003eDFF-A vs. ACT Activated-Carbon Adsorber\u003c\/h5\u003e\u003cp\u003eIn addition to the DFF-A, the range includes the separate \u003cstrong\u003eACT activated-carbon adsorber\u003c\/strong\u003e. Both are used to further reduce oil contaminants, but they are not identical. The ACT is a standalone activated-carbon adsorber with a downstream filter and is specified to achieve a residual oil content of up to \u003cstrong\u003e≤ 0.003 mg\/m³\u003c\/strong\u003e under defined conditions. The DFF-A, by contrast, is part of the modular DFF filter series and achieves \u003cstrong\u003e\u0026lt; 0.005 mg\/m³ at 20 °C\u003c\/strong\u003e under its specified conditions.\u003c\/p\u003e\u003ch5\u003eUse in a Multi-Stage Compressed-Air Treatment System\u003c\/h5\u003e\u003cp\u003eA possible treatment chain consists of condensate separation, prefiltration, drying, fine filtration or superfiltration, followed by the DFF-A. Not every application requires every stage. The required quality with regard to particles, water and oil is always the decisive factor.\u003c\/p\u003e\u003cdiv style=\"background:#f5f5f5;border-radius:10px;padding:18px;margin:22px 0;\"\u003e\u003ch5\u003eTypical Position of the DFF-A\u003c\/h5\u003e\u003cp style=\"margin:0;\"\u003e✅ After condensate separation and suitable prefiltration\u003c\/p\u003e\u003cp style=\"margin:0;\"\u003e✅ After fine filtration or superfiltration where a very low residual oil content is required\u003c\/p\u003e\u003cp style=\"margin:0;\"\u003e✅ As the final adsorption stage before sensitive downstream equipment\u003c\/p\u003e\u003cp style=\"margin:0;\"\u003e✅ Not intended as the sole filter for heavily contaminated untreated compressed air\u003c\/p\u003e\u003c\/div\u003e\u003ch5\u003eMaintenance and Filter Element\u003c\/h5\u003e\u003cp\u003eThe adsorption capacity of activated carbon decreases as contaminant loading increases.
