DFF-A compressed-air filter, oil mist removal, with filter element, max. 16 bar operating pressure, flow rate of 1.2–36.0 m³/min
The Comprag DFF-A activated carbon filters are highly efficient compressed-air filters for the final stage of compressed-air treatment. They remove oil vapors, odors, and organic vapors almost completely and produce technically oil-free compressed air with a residual oil content of < 0.005 mg/m³. With an operating pressure of up to 16 bar and flow rates ranging from 1.2 to 36.0 m³/min, they are ideal for the food, pharmaceutical, electronics, and surface treatment industries. They are compatible with DFF-P, DFF-M, and DFF-S pre-filters and, thanks to their replaceable filter element, are particularly easy to maintain.

Leasing & Rent-to-Own
Leasing & Rent-to-Own
We offer leasing and rent-to-own financing options exclusively to business owners, tradespeople, and the self-employed for selected products with a net merchandise value of €1,000 or more. Below you will find the key differences between these two financing options.
Leasing
In a lease, the product is made available to the lessee for use in exchange for regular lease payments. The lessor is responsible for accounting for the lease. The lease payments can generally be claimed as business expenses for tax purposes. These are gross payments, and value-added tax is charged throughout the entire term. At the end of the agreed-upon basic lease term, it is generally possible to purchase the product.
Hire Purchase
Hire purchase is economically equivalent to installment purchase. The product is capitalized on the hire purchaser’s balance sheet and depreciated in accordance with the official depreciation tables. Upon payment of the final hire purchase installment, ownership of the item is transferred to the hire purchaser. Value-added tax must be paid in full with the first hire purchase installment (transitory item).
Shipping & Delivery
Shipping & Delivery
Depending on the size, weight, and nature of our goods, they are shipped either via parcel service or freight carrier. We select the shipping method at our reasonable discretion.
The delivery times listed in the online store are non-binding estimates, unless a binding delivery date has been expressly confirmed in writing. They are based on the information available from our manufacturers, suppliers, and logistics partners at the time the order is placed.
Most of the products offered are shipped directly from the manufacturer or from external central warehouses (direct shipping). As a result, delivery times may differ from the estimated times provided. Delivery delays may occur, particularly in the event of material shortages, production delays, supply bottlenecks, force majeure, or other circumstances beyond our control.
Disclaimer:
We assume no liability for delivery delays resulting from circumstances beyond our control. This applies in particular to delays caused by manufacturers, suppliers, shipping companies, or other third parties. Liability for any resulting damages—in particular for indirect damages, consequential damages, or lost profits—is excluded to the extent permitted by law.
Partial deliveries are permitted, provided they are reasonable for the customer. This does not result in additional shipping costs, unless otherwise agreed.
The exact delivery time for an item can be provided on an individual basis upon request, either before or after the order is placed.
Please contact us by phone at +49 (0)2551 5030 or by email at shipping@strahltechnik-express.de.
In the event of significant delivery delays, we will inform the customer immediately. The customer’s mandatory statutory rights remain unaffected by this.

DFF-A Compressed-Air Filter for Low Residual Oil Content
The Comprag DFF-A compressed-air filter is the activated-carbon final stage in the DFF filter series. 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. At 20 °C, the specified maximum residual total oil content is < 0.005 mg/m³.
Depending on the model size, the series covers flow rates from 1.2 to 36.0 m³/min at 7 bar and is designed for a maximum operating pressure of 16 bar. The DFF-A does not replace upstream particle and coalescing filters; it complements them as the final fine-treatment stage.
DFF-A at a Glance
✅ Activated-carbon final stage for further reduction of gaseous oil components
✅ Residual oil content < 0.005 mg/m³ at 20 °C
✅ Flow rate: 1.2 to 36.0 m³/min, depending on model size
✅ Maximum operating pressure: 16 bar
✅ For use after suitable prefiltration
Function of the DFF-A Activated-Carbon Filter
Oil can occur in different forms within a compressed-air system. 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.
The 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 < 0.005 mg/m³ at 20 °C. This value assumes suitable upstream compressed-air treatment.
Why Prefiltration Is Necessary
Activated 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.
Within the DFF series, for example, DFF-P filters can be used for coarse filtration, DFF-M filters for microfiltration and DFF-S 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.
Technical Specifications and Selection
Filter principle: Activated-carbon adsorption
Maximum residual total oil content at 20 °C: < 0.005 mg/m³
Maximum operating temperature: 45 °C
Maximum operating pressure: 16 bar
Flow rate at 7 bar: 1.2 to 36.0 m³/min, depending on model size
Filter element: Replacement interval according to operating conditions and product specifications. The activated-carbon stage generally requires a shorter replacement interval than pure particle filtration stages.
The 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.
DFF-A vs. ACT Activated-Carbon Adsorber
In addition to the DFF-A, the range includes the separate ACT activated-carbon adsorber. 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 ≤ 0.003 mg/m³ under defined conditions. The DFF-A, by contrast, is part of the modular DFF filter series and achieves < 0.005 mg/m³ at 20 °C under its specified conditions.
Use in a Multi-Stage Compressed-Air Treatment System
A 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.
Typical Position of the DFF-A
✅ After condensate separation and suitable prefiltration
✅ After fine filtration or superfiltration where a very low residual oil content is required
✅ As the final adsorption stage before sensitive downstream equipment
✅ Not intended as the sole filter for heavily contaminated untreated compressed air
Maintenance and Filter Element
The adsorption capacity of activated carbon decreases as contaminant loading increases. Timely element replacement is therefore important even when no pronounced pressure drop is visible. High temperatures, moisture and inadequate prefiltration can shorten the service life. To maintain consistently low residual oil levels, the complete filter train should be serviced regularly.
