The AirTAC GC600C20ALF2WK AirTAC F.R.L. Combination, 3/4 in PT is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC series combines the three classic air-treatment stages - filter, regulator and lubricator - as three separate AirTAC units built into one F.R.L. supply. This GC600 configuration is made for 3/4 in PT piping and carries the 5 um filter element (code W) instead of the standard 40 um, an automatic drain on the filter bowl, a low-pressure regulator, an embedded square gauge reading in psi, a reverse/check valve, and a mounting bracket. At size 600 the bowls are aluminium alloy, the maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC line is published in sizes 200, 300, 400 and 600, with ports from 1/8 in to 1 in, drain choices (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge scales in MPa, psi or bar, and PT (standard), G or NPT thread options. Flow for this series is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application before ordering.

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 combination has no separate bracket code — the three 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. Constituent units, orderable separately as spares: GF600-C2 filter, GR600-C2 regulator and GL600-C2 lubricator.
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

Feeds spray guns and air tools at a body shop booth with water and particle removal down to 5 um, a low-pressure regulator setting and an oil mist to keep the guns lubricated.
Supplies filtered, regulated and lubricated air to pneumatic clamps and workholding fixtures on a machining centre, with the reverse/check valve guarding the circuit against backflow.
Conditions the air feeding pick-and-place cylinders and diverters on a bottling or cartoning conveyor, with the automatic drain clearing condensate from the filter bowl during runs.
Size and port step up together across the GC range: 200, 300, 400 and 600, with ports from 1/8 in to 1 in, so choose the size whose flow curve covers your demand - we can check the curve against your consumption if you send the figures. This unit already carries the 5 um element (W); the standard grade is 40 um if finer filtration is not required. The drain here is automatic; differential-pressure (the default) and manual drains are the other catalogue choices. The gauge is the embedded square type reading psi, with MPa and bar scales and an external round gauge as options. Thread is PT as standard, with G (BSPP) and NPT as coded options, and the bracket is included. Because the regulator in this code is the low-pressure type and its exact range is not published, confirm the setting band with us before ordering.
Quick checklist
The aluminium-alloy bowls on the GC600 suit harsher environments than PC bowls. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR600-C2 regulator with a GF600-C2 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure and air consumption and we will confirm the flow from the datasheet for this size 600, 3/4 in PT configuration.
It marks the low-pressure regulator type. The exact adjustment range for the L variant is not published in the material we hold, so please confirm the setting band with us before ordering. The rest of the code decodes as: automatic drain (A), square gauge with psi scale (F2), 5 um filter element (W) and a fitted reverse/check valve (K).
