Hankison NGF UF ultra-fine microfilters

The UF microfilter is the finest coalescing stage of the NGF range. It traps particles larger than 0.01 µm and removes oil down to a residual content below 0.001 mg/m³ — ten times less than the HF microfilter.
The UF 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 (yellow).
UF 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 UF microfilter is for applications where the air must be practically oil-free: powder coating, mould blow-off, pneumatic instruments, air bearings, pneumatic conveying and electronics manufacturing. It is also suitable as a pre-filter for a membrane dryer.
It can handle only a little liquid (at most 0.1 g/m³), so a PF dust filter belongs before it — at higher humidity the manufacturer explicitly recommends PF.
Where to place it

After the PF dust filter and HF microfilter, before CF activated carbon.
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 UF-06 for the F06-B-UF. 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 140 mbar wet.
Replace the element after 3,000 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
An ultra-fine filter needs a pre-filter. The UF microfilter can handle at most 0.1 g of liquid per cubic metre of air. A PF dust filter before it traps liquid and particles, and the UF element lasts longer.
- What purity does the UF microfilter provide?
- Particles down to 0.01 µm and residual oil below 0.001 mg/m³, class 1-x-1 according to ISO 8573-1.
- How does it differ from the HF microfilter?
- Same 0.01 µm rating, but ten times lower residual oil: below 0.001 mg/m³ compared with 0.01 mg/m³.
- When should the element be replaced?
- After 3,000 operating hours, within 12 months at the latest, or at a pressure drop of 400 mbar.
