The AirTAC GC600C20C2WK AirTAC F.R.L. Combination 3/4" 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 GC600C20C2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one complete air-treatment set. This 600-size configuration is fitted with 3/4" PT ports, a 5 um filter element (the finer of the two catalogue grades), differential-pressure drain bowls, a round pressure gauge reading in psi, a reverse/check valve on the regulator, and a mounting bracket. At size 600 the filter and lubricator bowls are aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8" to 1", and with choices of drain type, filter grade, gauge style and scale, thread form (PT standard; G and NPT as order options) and check valve. Flow figures for this series are published as curves rather than a single rating, so contact us and we will confirm the datasheet 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.

A 3/4" main air drop feeding assembly stations gets filtered, regulated and lubricated air in one GC set, keeping impact tools and air cylinders supplied with clean, moist-air-free supply at a set pressure.
Carton-forming and case-packing machines running many small cylinders benefit from the 5 um element protecting valve seals, the regulator holding a stable set pressure, and the lubricator misting the cylinder internals.
CNC clamping and fixture circuits need steady regulated pressure and clean air; the check valve helps hold the set downstream condition, and the psi gauge lets operators verify the setting at the machine.
Start with the size and port: this unit is the 600 size with 3/4" PT ports, the largest step in the GC range (200/300/400/600), so match it against the air demand of the circuit - if your consumption sits near the top of a smaller size, step up rather than down. Flow is published as curves, not a single rated figure, so ask us to confirm sizing against your application before ordering. Other decodable choices: the 5 um element fitted here is the finer option (40 um is standard); the differential-pressure drain is the default, with automatic and manual drains available; the round psi gauge is the external option (an embedded square gauge with MPa/psi/bar scales is standard); the K code means a reverse/check valve is fitted; and PT is the standard thread with G (BSPP) and NPT as catalogue options to order. A mounting bracket is included.
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 one number. Send us your line pressure and air demand and we will confirm the datasheet flow figures for this 600-size unit on request.
The W in the code specifies the 5 um element, the finer of the two catalogue grades (40 um is the standard default). It suits circuits with sensitive valves or cylinders. If your application is fine with coarser filtration, the 40 um grade is available in the same family - ask us for the equivalent model code.
