FUTURA filters, pre-filters and microfilters for ATEX environments up to 16 bar
FUTURA filters clean compressed air in four stages. The 5 µm filter separates water and coarse dirt, the pre-filter traps particles above 0.3 µm, the microfilter traps particles above 0.01 µm as well as oil mist, and the activated carbon filter removes odours and oil vapours.
Each type comes in four sizes with G 1/4" to 1" threads. Place the finer stages after the coarser ones; the elements then last longer.
Which filter to choose
Filter 5 micron
Basic filtration. Centrifugal force separates water droplets and coarse dirt, the sintered element traps particles above 5 µm.
Pre-filter 0.3 micron
Traps fine particles that pass through a 5 µm filter, with an efficiency of 99.99 %. Protects the microfilter element.
Microfilter 0.01 micron
The finest particles and oil mist, with an efficiency of 99.999 %. Residual oil 0.01 mg/m³, class 1 according to ISO 8573-1.
Activated carbon filter
Removes odours and oil vapours. Residual oil 0.005 mg/m³, class 0 according to ISO 8573-1. Does not drain condensate.

In which order to place the filters
In the direction of air flow, the 5 µm filter comes first, followed by the 0.3 µm pre-filter, the 0.01 µm microfilter and finally the activated carbon filter. Each stage protects the finer one after it. If you load a fine element with coarse dirt, it clogs quickly.
You do not have to use all the stages. For ordinary tools, a 5 µm filter is usually enough. Where you need very clean air, add a pre-filter and a microfilter, and where odour is a problem, an activated carbon filter.
Specifications by type
The flow of the pre-filter, microfilter and activated carbon filter is the optimum flow at an inlet pressure of 6 bar and a low pressure drop, when the element filters best. At a higher flow, the pressure drop increases.

In size 1, the pre-filter and microfilter with automatic drain have a shorter element, because there is a float in the bowl.
Bowl and condensate drain
The standard version has a plastic bowl and a semi-automatic drain. You choose another version as a variant on the product page. The activated carbon filter does not drain condensate; its bowl has no drain.
Plastic bowl
Transparent polycarbonate bowl, in sizes 1 to 4 in a protective guard. You can see the whole condensate level.
Metal bowl
For more demanding environments. With a sight glass in sizes 1 to 4, without one in size 0.
Semi-automatic drain
Condensate drains by itself when the pressure in the bowl drops, for example after the supply is shut off. In continuous operation, keep an eye on the level.
Automatic drain
A float releases the condensate during operation as soon as it rises. The version closed when depressurised stays closed after the air is switched off.

You can lead the condensate away through a hose. With the automatic drain, the hose screws into the G 1/8" thread in the drain outlet.
Clogging indicator
On the cap of the pre-filter and microfilter in sizes 1 to 4, you can fit the differential pressure indicator DDA-B (0–0.35 bar) or the differential pressure gauge DDA-M (0–0.5 bar). The pressure difference before and after the element shows you that the element is clogging.
Potentially explosive atmospheres
Filters in sizes 1, 2 and 4 are mechanical devices with no ignition source of their own. According to the declaration regarding Directive 2014/34/EU, you can use them in zones 1 and 2 (gases IIA, IIB, IIC) and 21 and 22 (dust IIIA, IIIB), temperature class T4, under the conditions described for the entire FUTURA range. Neither size 0 nor the clogging indicators are for use in potentially explosive atmospheres.
Mounting
Mount the filters upright only, bowl down, and in the direction of the arrow on the body. You fix them to a wall with a mounting bracket and to other components of the same size with a connection kit. The filter cannot be mounted in a panel.

Maintenance
The elements gradually clog and need replacing. Depressurise the filter before replacing the element. Pull the bowl catch down, turn the bowl to the left and remove it. Unscrew the element end piece and replace the element. Fit the bowl rotated by 45° and turn it to the right until the catch audibly clicks into place.
In size 0, the bowl is screwed on. Clean plastic bowls only with a damp cloth and water or a mild detergent; solvents damage polycarbonate.
Ventilek’s tip
A fine filter without a coarser stage before it clogs quickly. Put a pre-filter before the microfilter and a 5 µm filter before that. Each element then only traps what it is designed for and lasts longer.
- What is the difference between a pre-filter and a microfilter?
- The pre-filter traps particles above 0.3 µm, the microfilter particles above 0.01 µm and also oil mist. The pre-filter goes before the microfilter so that the microfilter element lasts longer.
- Does the activated carbon filter remove water?
- No. It traps odours and oil vapours and does not drain condensate. A 5 µm filter, a pre-filter and a microfilter go before it.
- Why does the pre-filter have a lower flow than the 5 µm filter?
- For the pre-filter, microfilter and activated carbon filter, the stated flow is the optimum flow at a low pressure drop, when the element filters best. Choose the size according to it.
- How can I tell that the element is clogged?
- On the pre-filter and microfilter in sizes 1 to 4, by the DDA-B differential pressure indicator or the DDA-M gauge. Otherwise by the pressure drop after the filter while air is drawn.
- What inlet pressure can the filters take?
- Up to 16 bar, size 0 up to 12 bar. The filter, pre-filter and microfilter work from 1.5 bar, the activated carbon filter from 0 bar.
- Are they suitable for potentially explosive atmospheres?
- Sizes 1, 2 and 4 are, in zones 1, 2, 21 and 22 according to the declaration regarding Directive 2014/34/EU. Size 0 and the clogging indicators are not.
Inlet pressure 1.5–16 bar, activated carbon filter 0–16 bar (size 0 up to 12 bar), working temperature −10 to +50 °C, compressed air and neutral gases. Filtration 5 µm, 0.3 µm and 0.01 µm, residual oil down to 0.005 mg/m³.
