How to read the GF number

Every element has its own Globe Filter number. It shows which brand the element replaces and its filter grade – so it is easy to reorder the right one next time.

GF-AC4120-K1

GF Globe Filter

AC Brand code (here: Atlas Copco)

4120 Serial number

K1 Filter grade (here: 1 µm)

Filter grades – from coarse to ultra-fine

K2525 µm

Coarse filter – removes large particles and rust.

K55 µm

Pre-filter – protects the finer filters.

K33 µm

Particulate filter for general compressed air.

K11 µm

Coalescing filter – removes water and oil aerosols.

K010.1 µm

Fine filter for higher air-quality requirements.

KX0.01 µm

High-efficiency fine filter – for demanding processes.

KAActivated carbon

Removes oil vapour, odour and taste.

Suffixes after the code: R = reverse flow · H = high temperature · D = duplex · S = silenced · P = push-fit.

Separators, activated carbon, OVR and special products have their own end codes (e.g. VS). The product type is always shown in the search result. The filter grade alone does not describe all performance – technical data for your part is available on request.
