The AirTAC GC600C20C2K AirTAC F.R.L. Unit 3/4 in, Round psi Gauge 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 GC600C20C2K is a three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one compressed-air treatment set. In this configuration the filter removes water and particulate down to 40 um with a differential-pressure drain, the standard regulator holds downstream pressure anywhere in its 0.15-0.9 MPa (20-130 psi) adjustment range, and the lubricator meters oil mist into the air line. The 3/4 in PT ports suit a main air drop or a large machine supply, the fitted round gauge reads in psi, and the reverse/check valve holds downstream pressure if the upstream supply is lost. At size 600 the bowls are aluminium alloy, and the set includes a mounting bracket.
This is a genuine AirTAC part from the GC series, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um (W) filtration, gauge scale options in MPa, psi or bar, and G (BSPP) or NPT thread variants. Flow performance 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-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.

Installed at the take-off point of a factory compressed-air ring main, the set cleans, regulates and lubricates the supply feeding an entire work cell, with the check valve protecting the cell from upstream pressure loss.
Mounted on the supply to a machining centre's clamping circuit, the filter keeps swarf-laden air out of the fixture cylinders, the regulator holds consistent clamp pressure and the lubricator conditions the actuator seals.
Fitted ahead of the valve manifold that drives conveyor gates, diverters and wrap stations, the unit delivers filtered, regulated, lubricated air so the line's cylinders and air bearings run on conditioned supply.
Start with the port and size step: this unit is size 600 with 3/4 in PT ports, the largest step in the GC range, chosen where the main line flow demand is highest - match it against your consumption before ordering, since flow is published as curves rather than a single rating and we will confirm sizing against your application on request. This set carries the standard 40 um filter grade with a differential-pressure drain; if you need finer filtration or automatic draining, the 5 um (W) grade and automatic-drain variants are orderable options in the same size. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) range, and the fitted round gauge reads in psi (MPa and bar scales are also catalogue options). Thread is PT as standard, with G (BSPP) and NPT available to order, and the included bracket simplifies panel or frame mounting. The K code means a reverse/check valve is fitted, which is worth specifying where a lost supply must not dump downstream pressure.
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 performance for the GC series as curves rather than a single rated figure, so we do not quote one number here. Tell us your working pressure and air consumption and we will confirm the datasheet flow curve and correct sizing for your application on request.
K means a reverse/check valve is fitted, so downstream pressure is held if the upstream supply fails. The drain on this unit is the differential-pressure type (the default, no drain letter in the code): condensate collected in the filter bowl is discharged automatically when the pressure differential across the filter rises, with no daily manual draining required.
