The AirTAC GC600-20 AirTAC F.R.L. Combination, PT3/4, 5 um 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 5 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC600-20 is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This configuration is sized for a PT3/4 port, carries the 5 um filter element (code W, in place of the 40 um standard), uses an automatic drain on the filter bowl, and includes the embedded square pressure gauge scaled in psi. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the lubricator delivers oil mist downstream to keep air tools and cylinders working. At size 600 the filter bowl is aluminium alloy, and the maximum inlet pressure is 1.0 MPa (145 psi) with an operating temperature range of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8" to 1", and options include manual or differential-pressure drains, the 40 um standard element, gauge scale in MPa, psi or bar, a reverse/check valve, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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 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 the take-off from a plant air receiver or main header, the filter cleans water and particulate from the compressed air, the regulator holds a steady downstream pressure, and the lubricator feeds oil mist to the tools and actuators served from that line.
Mounted ahead of the valve manifold on a packaging or conveyor line, this unit supplies filtered, regulated and lubricated air to the cylinders that clamp, push and divert product, with the automatic drain handling condensate without daily attention.
Fitted at the supply to a pneumatic press, clamping fixture or workholding circuit, it protects the directional valves and cylinders from water and 5 um-level particulate, holds the set working pressure on the psi gauge, and keeps lubrication mist in the air stream.
Start with the port and size step: this unit is size 600 with a PT3/4 port, the largest step in the range - step down to 200/300/400 if your line runs at lower flow. Choose the drain to match how the unit is attended: automatic (this unit) suits unattended or hard-to-reach installations, manual suits supervised points, and differential-pressure is the default. This unit carries the 5 um element (code W); the 40 um standard element is the usual choice for general plant air, with 5 um for finer protection. The embedded square gauge here reads in psi; MPa and bar scales are available, and an external round gauge is optional. Thread is PT as standard - order G (BSPP) or NPT if your piping needs it, and a mounting bracket is included. Flow for this series is published as curves, not a single rating, so ask us to confirm sizing against your application 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 this series as performance curves rather than a single rated figure, so no single flow number can be quoted here. Ask us and we will confirm the datasheet and the curve for the GC600 size, then check it against your application's flow demand before you order.
The W in the code GC60020AF2W selects the 5 um filter element instead of the 40 um standard, giving finer particulate protection; the A selects the automatic drain, which discharges condensate from the bowl without manual attention. If your air is already reasonably clean, the 40 um element, or a manual or differential-pressure drain, are the alternative decodable choices in this series.
