The AirTAC GC60020LC2K AirTAC F.R.L. Combination PT3/4 Low-Pressure 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 GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator delivered as one set. This GC60020LC2K is built for 3/4 in PT ports and is the low-pressure (L) regulator variant. It carries a differential-pressure drain on the filter bowl, 40 um standard filtration, a round psi gauge, a reverse/check valve and a mounting bracket. At size 600 the filter and lubricator bowls are aluminium alloy rather than polycarbonate, and the unit handles compressed air at up to 1.0 MPa (145 psi) inlet in a -5 to 70 C (non-freezing) environment.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options for drain type, 5 um (W) filtration, gauge style and scale, G or NPT threads and a reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application before ordering.

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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

On an automated assembly line, a 3/4 in PT main drop feeding banks of pneumatic clamp and press cylinders needs three things at once: water and chips removed before they score seals, a steady set pressure for repeatable clamp force, and a fine oil mist to keep cylinder seals and valves running smoothly. A single GC set on the drop does all three jobs in one mounting.
Truck and equipment maintenance bays run impact wrenches, nut runners and grinders off 3/4 in drops all day. The filter keeps rust and pipe scale out of the tool triggers, the regulator lets technicians set a safe working pressure for each job, and the lubricator mists oil into the tool air stream so vanes and bearings last.
Case packers, carton sealers and conveyor diverters on a packaging line use short, fast cylinder strokes fed from a 3/4 in header. The GC set conditions that header air: the 40 um filter protects the directional valves, the regulator holds actuator speed consistent from shift to shift, and the lubricator keeps the cylinders and fittings from wearing dry.
The real choices in this family are the size and port step (200/300/400/600 with ports from 1/8 to 1 in) matched to your line's air demand, the drain type on the filter (differential-pressure as here, automatic or manual), the filter grade (40 um standard, 5 um with W), the gauge (embedded square as standard, external round optional, in MPa, psi or bar scales), the thread (PT standard here; G and NPT are order options) and whether a reverse/check valve is fitted.
This unit is the low-pressure (L) regulator variant; the exact regulation range for that type is not published, so confirm it with us before ordering. Because flow is published as curves rather than a single rating, also ask us to check the datasheet against your required flow before you commit.
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, not as a single rated figure, so we do not quote a number here. Tell us your line's air demand and working pressure and we will confirm sizing against the datasheet before you order.
It marks the low-pressure regulator variant rather than the standard type. The exact regulation range for the low-pressure type is not published in the catalogue, so confirm the range with us on request before ordering if your application sits near the top or bottom of your set pressure.
