Hankison NGF SF basic filters with liquid separator
The SF basic filter combines a mechanical liquid separator with a 3 µm coalescing filter. It removes over 99% of liquid condensate and traps solid particles larger than 3 µm; residual oil is 5 mg/m³.
The SF filter comes in 14 sizes, F02 to F17, with G 1/4" to G 3" threads and flows of 566 to 42,483 l/min. It is one of the five stages of the Hankison NGF filters — the housing is the same for all stages; only the element with its coloured end cap differs (orange).
SF filters by size
The size determines the thread, the flow and the element. Each size has its own spare element.

The flows apply to a pressure of 7 bar and a temperature of +20 °C. You will find the dimensions and weight on the product page of each filter.

When to use it
The SF basic filter suits places where a lot of liquid water enters the air — in air lines without an aftercooler and dryer, or directly after the compressor. It separates water and solid contaminants for workshop and blow-off air.
The manufacturer states solid particle class 3 and oil class 5 according to ISO 8573-1 and an oil removal efficiency of 50%. For oil, add finer stages after it.
Where to place it
At the start of the filtration, before the PF dust filter or directly before the HF microfilter.
Flow by pressure
The catalogue flows apply to a pressure of 7 bar and a temperature of +20 °C. At a different pressure, they change according to the correction factor: at a lower pressure the filter passes less air, at a higher pressure more. Sizes F13 to F17 work up to 11 bar.

Sizes
The smallest filter, F02, is 205.5 mm tall, the largest, F17, 1,085.1 mm. You will find the width, height, connection axis and the clearance below the filter for element replacement on the product page of each size.
Element and maintenance
The housing holds one element, a different one for each size — for example SF-06 for the F06-B-SF. The coloured end cap of the element identifies the filtration stage, so elements cannot be mixed up during replacement.
The pressure drop of a new element is 60 mbar dry and 70 mbar wet.
Replace the element after 6,000 operating hours, within 12 months at the latest, or at a pressure drop of 400 mbar.
Housing
The housing is die-cast aluminium, chromated and protected by a powder coating. The element hangs in the filter head, and air enters it through the shaped Venturi-Wave end cap without turbulence; the bowl has internal ribs along which the condensate runs down.
Standard equipment
The filter is supplied with an element, a pressure drop indicator on the head and an automatic condensate drain depending on the size:
| Equipment by size | ||
|---|---|---|
| Sizes | Clogging indication | Condensate drain |
| F02 – F07 (SF, PF, HF, UF) | pressure drop indicator on the head | automatic float drain |
| F08 – F12 (SF, PF, HF, UF) | differential pressure gauge on the head | automatic float drain |
| F13 – F17 (SF, PF, HF, UF) | differential pressure gauge on the head | level-controlled electronic drain |
| F02 – F17 (CF) | no indication (activated carbon is replaced by time) | manual valve (ball valve) |
Ventilek’s tip
Where there is water, start with SF. Where a lot of condensate forms in the air line, the SF basic filter separates the liquid before it floods the fine elements after it.
- What does the SF basic filter trap?
- Over 99% of liquid condensate and solid particles larger than 3 µm. Residual oil is 5 mg/m³.
- How much liquid can it handle?
- The manufacturer states a maximum of 25 g of liquid per cubic metre of air.
- When should the element be replaced?
- After 6,000 operating hours, within 12 months at the latest, or at a pressure drop of 400 mbar.
