FUTURA pressure regulators with filter for ATEX environments up to 16 bar
The FUTURA pressure regulator with filter cleans the air with a 5 µm filter and, in the same body, reduces the pressure to the value you set with the knob. Compared with a separate filter and regulator, it saves space and one joint.
It comes in four sizes with G 1/4" to 1" threads and in ranges from 0.1–1 bar to 0.5–16 bar. The pressure gauge is always included.
Which version to choose
Filter regulator
Sizes 1, 2 and 4 with G 1/4" to 1" threads and a 50 mm pressure gauge. The 0.5–8 bar range is the most versatile.
Size 0
The smallest version, G 1/4", with a compact pressure gauge, or with a 40 mm pressure gauge as a variant. Inlet pressure up to 12 bar.
Safety version
With an upstream ball valve that you lock with a padlock, and with a soft-start valve for gradual pressure build-up.
Metal bowl and automatic drain
You choose the bowl and the condensate drain type as a variant on the product page.
Filter regulators by size
Rows are setting ranges, columns are threads. The pressure gauge matches the range.
Inlet pressure 1.5–16 bar, for size 0 1.5–12 bar. The 0.5–8 bar range is the most versatile. Size 0 is not for use in potentially explosive atmospheres.

How the filter regulator works
In the bowl, the air is first set spinning. Centrifugal force throws water droplets and coarse dirt against the wall, and they run down to the bottom of the bowl. The air then passes through the sintered 5 µm filter element and only then, cleaned, goes into the regulator.
The regulator reduces the pressure to the set value and holds it. When the outlet pressure rises above the set value, it releases the excess by itself. You lock the knob by pushing it in, and in sizes 1 to 4 also with a padlock.
The filter separates water that has already condensed. It does not trap water vapour. In the assembly, the filter regulator goes before the lubricator.
Bowl and condensate drain
The standard version has a plastic bowl and a semi-automatic drain. You choose the metal bowl and automatic drain as a variant on the product page.
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.
| Bowl and drain versions by size | ||||

| Metal, semi-automatic | yes | yes | yes | yes |
| Metal, automatic | yes | yes | yes | yes |
| Metal, automatic closed when depressurised | – | – | – | G 1" only |
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.
Safety version
A ball valve and a soft-start valve are fitted before the filter regulator. Before maintenance you close the valve, the outlet is exhausted and you lock the valve with a padlock. At start-up, the soft-start valve fills the air line gradually, so the cylinders do not move abruptly. You set the filling time with a screw.

Potentially explosive atmospheres
Filter regulators 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. Size 0 is not for use in potentially explosive atmospheres.
Mounting
Mount the filter regulator upright only, bowl down, and in the direction of the arrow on the body. You fix it to a wall with a mounting bracket, in a panel with a nut, and to other components of the same size with a connection kit.

Maintenance
The element gradually clogs and needs replacing. Depressurise the regulator before replacing it. 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
Without a lubricator, a filter regulator is enough. It cleans the air and holds the pressure in one body. When you also need lubricated air, add a lubricator after it, or go straight for a two-piece unit.
- How finely does the filter regulator clean?
- The filter element traps particles larger than 5 µm. Water droplets and coarse dirt are separated beforehand by centrifugal force in the bowl. For finer filtration, add a 0.3 µm pre-filter or a 0.01 µm microfilter.
- Is the pressure gauge included?
- Yes. Size 0 has a compact pressure gauge, with a 40 mm pressure gauge as a variant. Sizes 1 to 4 have a 50 mm pressure gauge.
- When should I choose the automatic drain?
- When the equipment runs for long periods without a break. The semi-automatic drain only releases condensate when the pressure in the bowl drops, so in continuous operation the condensate could overflow into the air line.
- What is the safety version?
- A filter regulator with an upstream ball valve that you lock with a padlock, and with a soft-start valve for gradual pressurisation after start-up.
- What inlet pressure can it take?
- Up to 16 bar, size 0 up to 12 bar. For the regulator to work properly, it needs at least 1.5 bar at the inlet.
- Is it 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 is not.
Inlet pressure 1.5–16 bar (size 0: 1.5–12 bar), setting ranges 0.1–16 bar, 5 µm filtration, working temperature −10 to +50 °C, compressed air and neutral gases. Relief of excess outlet pressure, pressure gauge included.
