The AirTAC AirTAC GC600C20AC2GK 3/4" F.R.L. Unit (G Thread) 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 AirTAC GC series is a three-unit F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator piped together, so one assembly cleans the compressed air, holds a set working pressure and carries oil mist downstream to pneumatic tools and cylinders. This GC600C20AC2GK is built on the 600 size with a 3/4 inch port and G (BSPP) thread. It carries the standard 40 um filter element with an automatic drain on the filter bowl, a standard-type regulator adjustable from 0.15-0.9 MPa (20-130 psi), a round external gauge reading in psi, and a reverse/check valve fitted. The maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). At size 600 the bowls are aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GC series spans sizes 200, 300, 400 and 600, with port sizes from 1/8 inch to 1 inch, PT/G/NPT thread options, differential-pressure, automatic or manual drains, a 5 um (code W) filter element option, gauge scale choices of MPa, psi or bar, and an optional reverse/check valve. Flow is published by AirTAC as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing figures for your application on request.

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.

Dropped from a 3/4 inch compressed-air ring main, the unit filters water and particulate from the plant supply, regulates the branch pressure for the assembly tools, and meters oil mist to keep impact wrenches and nut runners lubricated through a full shift.
On a beverage bottling line, the combination feeds the conveyor stop-gates, pushers and lift cylinders: the 40 um element protects the valve seats, the regulator holds a steady working pressure so cylinder timing stays repeatable, and the lubricator extends seal life on continuous-duty air cylinders.
Feeding a CNC workholding clamping circuit, the unit dries and filters the shop air before it reaches the clamping valves, the regulator holds the clamping pressure set on the psi gauge, and the reverse/check valve helps hold the circuit if supply pressure dips.
Start with the size and port: 200/300/400/600 step up in both port size and flow capacity, so match the size to the air demand of the circuit rather than to the pipe alone; this unit is the 600 size on a 3/4 inch port. Choose the drain: automatic drains the filter bowl without attention, manual needs operator action, and the differential-pressure default drains only when the element loading calls for it. Filter grade is 40 um as standard here, with a 5 um element (code W) available where finer particulate removal is needed. The gauge can be ordered embedded square or external round, in MPa, psi or bar scales - this configuration has a round psi gauge. Thread is PT as the AirTAC standard, with G and NPT as order options; this unit is G. A bracket is included, and a reverse/check valve is fitted here. Because AirTAC publishes flow as curves rather than a single rating, 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-C2 regulator with a GF600-C2 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote one number. Tell us your inlet pressure and the air demand of your circuit and we will confirm the flow from the datasheet curves on request before you order.
Both are decoded from the model code. The A position sets an automatic drain, which expels collected condensate from the filter bowl without operator attention - useful on lines that run unattended. The C2 position sets an external round gauge reading in psi; an embedded square gauge is the standard alternative, and MPa or bar scales can be ordered.
