Product detailed description
The Hankison NGF F03-B-HF coalescing microfilter traps solid and liquid particles larger than 0.01 µm and removes over 99.9% of oil aerosol; residual oil is below 0.01 mg/m³. It has a G 3/8" thread, a flow of 983 l/min (59 Nm³/h) at 7 bar and a working pressure of up to 16 bar.
It belongs to the range of Hankison NGF filters: the housing is the same for all five stages, and the stage is determined by the element with its coloured end cap.

Housing and dimensions
The housing is die-cast aluminium, chromated and protected by a polyester epoxy powder coating. The inlet and outlet are shaped as flanges with a female thread; the bowl has internal ribs along which the condensate runs down.
Dimensions according to the manufacturer: width A 113.6 mm, height B 205.5 mm, connection axis to bottom edge C 171.4 mm, and a clearance D of 102 mm is needed below the filter so that the bowl can be removed. Weight 0.8 kg.
Standard equipment
The filter is supplied with the HF-03 element, a pressure drop indicator on the head and an automatic float condensate drain.
The indicator on the head monitors the pressure drop of the element: as the element clogs, the pressure drop rises. However, also replace the element by time, even if the indicator does not yet signal it.
Flow by pressure
The flow applies to a pressure of 7 bar and a temperature of +20 °C. At a different pressure, it changes according to the correction factor; this filter works up to 16 bar:
| Pressure (bar) | 4 | 5 | 6 | 7 | 8 | 10 | 12 | 14 | 16 |
|---|---|---|---|---|---|---|---|---|---|
| Flow (l/min) | 619 | 737 | 865 | 983 | 1,110 | 1,356 | 1,621 | 1,838 | 2,093 |
When to use it
It suits the end of the air line before the point of use, as an oil coalescing filter and as a pre-filter for a membrane or adsorption dryer.
Where to place it
It goes after the PF dust filter, which protects it, and before CF activated carbon or a dryer.
Element and maintenance
Replace the HF-03 element (green end cap) after 3,000 operating hours, within 12 months at the latest, or at a pressure drop of 400 mbar.
Filter medium
The element has the patented Venturi-Wave shape, through which air enters the element without turbulence, and a deep pleated filter medium with a large area — air passes through it with a lower pressure drop.
You will find other sizes among the filters of the same stage, and spare elements in the NGF accessories.

Hankison is an American manufacturer of compressed air dryers and filters with a history going back to 1948. We offer its NGF filters in five filtration stages, spare elements for them and HDI refrigeration dryers.
NGF filters use the same housing for all stages, only the element differs — you can recognise the stage by the colour of the end cap. Stages SF to UF come with a pressure drop indicator and a condensate drain. HDI dryers dry the air to a pressure dew point of +3 °C.
Purity to ISO 8573-1NGF filters and HDI dryers
NGF filters — the whole range
Five stages in one housing. The stages are installed one after another from coarse to fine, each protecting the next.
- 14 sizes, G 1/4″ to 3″
- flow from 566 to 42,483 l/min
- up to 16 bar, F13 to F17 up to 11 bar
SF basic filter
At the start of filtration, where there is a lot of water. A liquid separator and 3 µm filter removes more than 99 % of liquid condensate.
- residual oil below 5 mg/m³
- handles up to 25 g of liquid per m³ of air
- orange element end cap
PF dust filter and pre-filter
Before a microfilter and after a desiccant dryer. A double depth layer captures particles from 1 µm with 99.999 % efficiency.
- residual oil below 2 mg/m³
- protects the HF and UF microfilter elements
- white element end cap
HF microfilter
Air free of oil aerosol. A coalescing filter that captures particles from 0.01 µm and removes more than 99.9 % of oil.
- residual oil below 0.01 mg/m³
- class 1-x-1 according to ISO 8573-1
- green element end cap
UF ultra-fine microfilter
For painting and sensitive instruments. The same 0.01 µm rating as HF, but ten times less oil in the air.
- residual oil below 0.001 mg/m³
- needs a PF dust filter upstream
- yellow element end cap
CF activated carbon filter
Oil vapours, odours and tastes. Two layers of activated carbon for air that comes into contact with food or medicines.
- oil vapour below 0.004 mg/m³
- always after an HF or UF microfilter
- element replaced after 1,000 hours
NGF spare elements
For all five stages and 14 sizes. The element code is the stage plus the filter size, such as HF-06 for the F06-B-HF filter.
- replace at a pressure drop of 400 mbar
- after 12 months at the latest
- stage shown by the end cap colour
HDI refrigeration dryers
Dry air with a +3 °C dew point. A patented aluminium heat exchanger cools the air in two stages and saves energy.
- 17 sizes, 200 to 21,667 l/min
- working pressure up to 16 bar
- 230 V up to HDI-600, larger sizes 400 V

| HDI dryer | water vapour | dew point +3 °C | – | x-4-x |
The ISO 8573-1 class is written as solid particles – water – oil; x means the product does not deal with that component.
How to set up air treatment
1. Pre-filter before the dryer
An HDI refrigeration dryer needs a pre-filter rated 10 µm or finer upstream — the manufacturer requires it. Where there is a lot of water in the system, an SF basic filter does the job.
2. Dryer to match the compressor
The dryer must handle the full output of the compressor. Choose the HDI size whose flow is at least equal to the compressor output.
3. Filters after the dryer
A refrigeration dryer is followed by a PF dust filter and an HF microfilter, or a UF ultra-fine microfilter for painting and sensitive instruments. Put CF activated carbon at the very end.
4. Replace elements on time
SF and PF after 6,000 operating hours, HF and UF after 3,000, CF after 1,000 — always after 12 months at the latest, or earlier at a pressure drop of 400 mbar.
Frequently asked questions
- What is the difference between the HF and UF microfilters?
- Both capture particles from 0.01 µm. The UF ultra-fine microfilter, however, leaves ten times less oil in the air: below 0.001 mg/m³ compared with 0.01 mg/m³ for HF.
- Why does a PF dust filter go before the microfilter?
- The PF dust filter captures solid particles and liquid before they reach the fine microfilter element. The HF or UF element then lasts longer.
- How do I recognise the element stage?
- By the end cap colour: orange SF, white PF, green HF, yellow UF and black CF. Each filter size has its own element, and the element code ends with the size number.
- Does an NGF filter also remove moisture?
- No. Filters only capture water that has already condensed. Water vapour is removed by a dryer — an HDI refrigeration dryer dries the air to a pressure dew point of +3 °C.
- Is an HDI dryer suitable for an unheated hall?
- Only where the temperature does not drop below zero. A +3 °C dew point means water will not condense until the temperature falls below +3 °C. For systems exposed to frost you need a desiccant dryer with a dew point below 0 °C.
