The AirTAC AirTAC GFC600-20 Combination Unit (GFC60020AF1K) is a genuine G-series two-unit air-preparation set: a filter regulator that filters and regulates in one body, coupled to a lubricator. Two bodies do the work of three, with PT3/4" ports, a 40 µm element, a automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).
GFC60020AF1K is an AirTAC GFC two-unit set for compressed air: a 600-size filter regulator paired with a lubricator, so one order covers water and particulate removal, pressure regulation and oil-mist lubrication. This configuration has a PT3/4 port, an automatic drain on the filter bowl, the standard 40 um filter element, an embedded square pressure gauge with MPa scale, and a reverse-flow (check) valve fitted so air cannot back-feed through the set.
This is a genuine AirTAC part. The G series is built in 200, 300, 400 and 600 sizes with ports from 1/8 in. to 1 in. and PT, G(BSPP) or NPT threads; at 600 size the bowls are aluminium alloy, working pressure is up to 1.0 MPa (145 psi), temperature range is -5 to 70 C, and the regulator adjusts 0.15-0.9 MPa (20-130 psi) on this automatic-drain version. Rated flow is published as curves rather than a single figure; ask us and we will confirm the datasheet figures for your application.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). The set has no separate bracket code — the two units couple together with their own mounting hardware. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination set. Constituent units, orderable separately as spares: GFR600-20 filter regulator and GL600-20 lubricator.
A GFC is two units because filtering and regulating share one body. A GC is three separate units — filter, regulator and lubricator. Both filter, regulate and lubricate; the GFC is the shorter assembly, the GC keeps the filter and regulator serviceable as separate bodies.

Feeds impact guns and ratchets at a service bench with filtered, regulated and oil-mist-lubricated air; the check valve stops air from back-feeding through the set from the tool side.
Supplies clamping cylinders on a furniture press, with the regulator set to the clamp circuit pressure and the 40 um element catching pipe scale and carried-over water.
Keeps the pusher cylinders that move bottles between lanes supplied with clean, regulated, lubricated air across a shift while the automatic drain clears the bowl on its own.
Size 600 with a PT3/4 port is the step to take when your circuit is built around 3/4 in. piping and higher air demand; smaller 200-400 sizes use smaller ports and suit lighter duties. The A in the code gives an automatic drain, so condensate leaves the bowl without operator attention, and this drain type carries the 0.15-0.9 MPa (20-130 psi) adjustment range. The 40 um standard element suits general plant air; choose W for 5 um. The F1 gauge is the embedded square gauge on an MPa scale (F2/F3 give psi/bar). PT is the standard thread; G and NPT are catalogue options.
Flow for this family is published as curves, not a single rating, so ask us to confirm sizing against your pressure and demand before ordering.
Quick checklist
The aluminium-alloy bowls on the GFC600 suit harsher environments than PC bowls. The lubricator adds an oil mist downstream, so if any branch must stay oil-free, take that branch off before the lubricator or use a GFR600-20 filter regulator on its own.
AirTAC publishes G-series flow as performance curves, not a single rated figure, so we do not quote a number here. Tell us your working pressure and air demand and we will confirm the datasheet curve for this 600-size, PT3/4 set before you order.
K means a reverse-flow (check) valve is fitted, so air cannot flow back through the set. Drop the K for the standard version, and if you need psi or bar on the square gauge instead of MPa, the catalogue scales are 2 and 3.
