The AirTAC GC60020C2GK AirTAC F.R.L. Combination, G3/4 Port 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 PT3/4" ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC60020C2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply package. This 600-size unit carries a G3/4 (3/4 inch) G-thread port, a 40 um filter element with a differential-pressure drain on the filter bowl, a standard regulator adjustable from 0.15 to 0.9 MPa (20-130 psi), and an oil-mist lubricator for downstream air tools and cylinders. The bowls on this size are aluminium alloy, a round external gauge on a psi scale is fitted, and a reverse/check valve is included to hold downstream pressure if the upstream supply drops.
This is a genuine AirTAC part. The GC range spans sizes 200, 300, 400 and 600 with port options from 1/8 to 1 inch, PT as the standard thread and G or NPT as order options, plus choices of drain type, 5 um filtration (code W), gauge scale and check valve. Rated flow for this series is published as curves rather than a single figure, 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: GF600-20 filter, GR600-20 regulator and GL600-20 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.

Installed at a 3/4 inch branch take-off from the main compressor ring main, the GC60020C2GK filters water and particulate, holds a set working pressure for the whole drop, and mists oil into the line feeding air tools and cylinders on the shop floor.
Feeding the air circuit of a CNC machining centre, the unit cleans the supply to 40 um, regulates it to the pressure the machine's valves and clamps need, and lubricates the actuated components, with the check valve holding settings during supply dips.
On the air supply to a packaging or conveyor line with many small cylinders, the GC60020C2GK provides filtered, regulated and lubricated air so the line's actuators run on a stable, conditioned supply shift after shift.
Start with the port step: this GC600 unit is the 3/4 inch (G3/4) size in the range, the step to choose when the line and connected air demand sit above what the 200/300/400 sizes serve - match the size to the required flow, which we confirm from the published curves on request. The filter element here is the 40 um standard grade; if finer particulate protection is needed, the W option gives 5 um. Drain is differential-pressure on this configuration; automatic (A) and manual (M) drains are available in the family if your maintenance routine suits them better. The fitted round gauge reads in psi; MPa and bar scales are the other catalogue choices. Thread is G (BSPP) on this unit - PT is the standard series thread and NPT is an order option. A reverse/check valve (K) is fitted to prevent backflow and hold downstream settings. We recommend confirming sizing against your application 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 GR600-20 regulator with a GF600-20 filter on that branch.
AirTAC publishes flow for the GC series as performance curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and the air demand of the equipment you are feeding, and we will confirm the sizing from the datasheet curves on request before you order.
K means a reverse/check valve is fitted, so air will not flow back toward the regulator and downstream pressure is held if the upstream supply drops. The drain on this unit is the differential-pressure type on the filter bowl: it discharges collected condensate automatically when the pressure difference across the filter reaches the discharge point. Automatic and manual drains are available as order options.
