The AirTAC GC60020C2K AirTAC F.R.L. 3/4 in Filter Regulator Lubricator 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 GC60020C2K is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one 3/4 in PT-port unit. It conditions compressed air in a single installation point - the 40 um filter element removes water and particulate, the standard regulator holds downstream pressure within its 0.15-0.9 MPa (20-130 psi) adjustment range, and the lubricator feeds an oil mist to downstream tooling. This 600-size configuration carries a differential-pressure drain on the filter bowl, an external round gauge reading in psi, and a reverse/check valve fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC series is available in 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in, a choice of PT, G or NPT thread, 40 um standard or 5 um (W) filtration, automatic, manual or differential-pressure drains, and gauge scale options in MPa, psi or bar. Flow is published as curves rather than a single rated figure, so we 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: GF600-20 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 point of a factory compressed-air main, the unit filters water and scale from the supply, holds a set header pressure for the whole cell, and mists oil into the distribution line serving air tools and cylinders.
Feeding the cylinders and air-actuated diverters on a packaging or conveyor line, the combination keeps regulated pressure stable for consistent stroke timing, delivers lubrication to actuation seals, and the check valve holds downstream pressure if the main supply dips.
On a heavy-vehicle service bay drop line running impact wrenches, tyre chucks and air ratchets, the 3/4 in unit conditions the shop supply, the psi round gauge lets technicians set and read working pressure directly, and the lubricator keeps tool internals oiled through a shift.
Size and port are the first decision: the 600 size with its 3/4 in PT port is the largest step in the GC range, so match it to the pipe diameter and the flow your line needs - if you are between sizes, ask us to confirm flow against the published curves before ordering. The 40 um standard element suits general plant air; specify the 5 um (W) grade where downstream valves or instruments need finer filtration. Drain type here is differential-pressure (the code default); automatic (A) and manual (M) drains are orderable alternatives. The C2 code gives you the external round gauge on a psi scale - MPa and bar scales are available if your team reads metric. The K code means a reverse/check valve is fitted; omit it where the circuit does not need one. Thread is PT as standard, with G (BSPP) and NPT as order options, and 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 GR600-20 regulator with a GF600-20 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated number, so we do not quote a rated flow, Cv or SCFM figure. Send us your line pressure and the flow your application needs and we will confirm the sizing against the datasheet curves on request before you order.
C2 means this unit is fitted with the external round gauge reading on a psi scale (MPa and bar scales are orderable alternatives), and K means a reverse/check valve is fitted to hold downstream pressure against supply loss. The 40 um filter element and differential-pressure drain are the code defaults for this configuration.
