Product detailed description
The HFC-047 cyclone separator removes liquid water, oil and coarse solid contaminants from compressed air. It separates them by centrifugal force, without a filter element. It has a G 1 1/2" thread, a flow of 4,700 l/min at 7 bar and a working pressure of up to 50 bar.
It belongs to the range of Omega Air HF filters up to 50 bar: the housing is the same as on these filters, but instead of a filter element it contains a cyclone element.

Housing and dimensions
Housing: cast aluminium with powder coating. The air is connected through female pipe threads in the head; the condensate leaves through a G 1/2" opening at the bottom. Dimensions according to the manufacturer: 535 × 160 × 45 × 260 mm, weight 9.5 kg.
Flow by pressure
The flow applies to a pressure of 7 bar and a temperature of +20 °C. At a different pressure, it is multiplied by the manufacturer’s correction factor:
| Pressure (bar) | 3 | 5 | 7 | 10 | 13 | 16 | 20 | 30 | 40 | 50 |
|---|---|---|---|---|---|---|---|---|---|---|
| Flow (l/min) | 2,350 | 3,525 | 4,700 | 6,486 | 8,225 | 10,011 | 12,361 | 18,236 | 24,111 | 29,986 |
Cyclone element and accessories
The separator collects a lot of water, so it needs a condensate drain, which is ordered separately. Suitable drains: AOK50B and AOK50SS. The spare cyclone element is listed in the specifications table.
Where to place it
It goes after the compressor or aftercooler, before the HF filters. It traps liquid water and oil before they reach the filters, so the filter elements clog less.
You will find all sizes and pressures among the HFC cyclone separators.

Omega Air is a Slovenian manufacturer of compressed air treatment equipment based in Ljubljana. Founded in 1988, the company now has 370 employees and exports to more than 80 countries. It has its own development team and patents and carries out almost all production in its own facilities.
We mainly offer industrial filters up to 420 bar with replacement elements, stainless steel process and sterile filters, refrigeration, desiccant and membrane dryers, activated carbon columns, oil-water separators and condensate drains. They are used in workshops and large plants, in food, pharmaceuticals, chemicals and paint shops.
Slovenian manufacturerOmega Air filters, dryers and separators
Industrial filters up to 50 bar
Filters for standard air lines. AAF and BF ranges up to 16 bar, BFHP up to 25 bar and HF up to 50 bar. The element sets the filtration grade.
- from coarse filter to activated carbon
- G 1/8" to 3" thread or DN80 to DN300 flanges
- AAFHT for hot air up to +120 °C
CHP and IHP high-pressure filters
For 100, 250 and 420 bar. CHP housings are nickel-plated carbon steel, IHP housings stainless steel.
- 8 sizes with G 1/4" to 2" thread
- flow 667 to 11,917 l/min at 7 bar
- six grades up to activated carbon
Stainless steel process filters
1.4404 stainless steel for food and pharma. Six ranges up to 14 and 50 bar with thread, flanges or welding ends.
- 12 filtration grades in each range
- sterile element in the PF and HPF ranges
- flow 1,250 to 352,000 l/min at 7 bar
RDS refrigeration dryers
Dew point +3 °C for most plants. The air cools down in the dryer, water condenses and the drain removes it without losing air.
- 18 sizes, 333 to 31,667 l/min
- working pressure up to 16 bar
- controller shows the dew point
ADRY desiccant dryers
Very dry air, dew point −40 °C. Moisture is captured by desiccant in two alternating columns.
- 9 sizes, 6 to 200 Nm³/h
- dew point −25 or −70 °C on request
- inlet and outlet filter included
MADRY membrane dryers
They dry without electricity. Water vapour passes through the wall of hollow fibres, dry air stays inside.
- 12 sizes, 50 to 3,000 l/min
- dew point down to −40 °C, up to 12 bar
- fine pre-filter and microfilter included
TAC activated carbon columns
They capture oil vapours that filters let through. The air flows through a bed of granular activated carbon.
- outlet oil below 0.003 mg/m³
- 19 sizes, 6 to 1,200 Nm³/h
- up to 16 bar, high-pressure TACHP up to 420 bar
WOS oil-water separators
They separate oil from condensate. Oil stays in the polypropylene fibre and activated carbon fills, water flows out.
- residual oil below 10 ppm
- 4 sizes for compressors up to 35.5 m³/min
- fills are replaced once a year

How to put compressed air treatment together
1. Define the quality
Choose the ISO 8573-1 purity class for the application: three numbers for solid particles, water and oil. A workshop needs 3:4:4, painting 1:4:1 and food in direct contact 1:2:1.
2. Order the grades
A separator or basic filter goes right after the compressor, followed by the dryer and the finer grades. Always place the 0.1 µm fine pre-filter before the 0.01 µm microfilter and activated carbon only after the microfilter.
3. Choose the size
Select the filter and dryer by compressor flow and line pressure. Flows are given at 7 bar; at lower pressure a filter passes less air.
4. Maintain
Replace elements once a year, sooner if the pressure drop rises. Remove condensate with a drain and replace the WOS separator fills once a year.
Frequently asked questions
- What is the difference between a fine pre-filter and a microfilter?
- A fine pre-filter captures particles down to 0.1 µm and oil to 0.1 mg/m³, a microfilter down to 0.01 µm and 0.01 mg/m³. The pre-filter always goes before the microfilter to protect its element.
- How do I find a replacement element for an Omega Air filter?
- The element has the same code as the filter with the letter V at the end: the AAFP-78 filter takes the AAFP-78V element. Most elements are replaced once a year, sooner if the indicator shows a higher pressure drop.
- Which Omega Air dryer should I choose?
- For workshops and most plants an RDS refrigeration dryer with a +3 °C dew point is enough. Very dry air or lines exposed to frost need an ADRY desiccant dryer with a −40 °C dew point. The MADRY membrane dryer needs no electricity and suits small flows right at the machine.
- Where does an activated carbon column go?
- After the dryer and a 0.01 µm microfilter, which captures oil droplets and aerosol. The column then removes oil vapours below 0.003 mg/m³. A 1 µm dust filter goes after it to catch dust from the carbon.
- What is an oil-water separator for?
- Condensate from an oil-lubricated compressor contains oil and must not go into the sewer untreated. The WOS separator captures the oil in its fills and water flows out with less than 10 ppm residual oil. The discharge limit is set by the local sewer regulations.
- Which condensate drains does Omega Air make?
- Manual MCD drains, float AOK drains that work without electricity, timed TD drains up to 420 bar and the electronic AD20. It senses the level with a capacitive sensor and drains condensate without losing air.
