The AirTAC GC60020MLC2GK AirTAC F.R.L. Combination Unit, G3/4 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The AirTAC GC60020MLC2GK is a three-piece F.R.L. air-treatment combination: a separate filter, a pressure regulator and an oil-mist lubricator assembled as one GC set. It cleans compressed air of water and particulate down to the standard 40 um grade, regulates downstream pressure with a low-pressure type regulator, and adds oil mist for downstream air tools and cylinders. This size-600 unit is built with G3/4 ports, a manual drain on the bowls, a fitted round gauge reading in psi, and a reverse/check valve on the regulator. The aluminium alloy bowls suit this top size, and a mounting bracket is included.
This is a genuine AirTAC part. The GC line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, and options that include automatic, manual or differential-pressure drains, a 5 um filter element (code W), 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 the datasheet and sizing 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.

|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |

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.

A 3/4 in branch feeding assembly stations: the filter strips water and 40 um particulate from the main supply, the low-pressure regulator holds a gentle setpoint for sensitive actuators, and the lubricator feeds mist to the air tools at each station.
Packaging conveyors and bottle-gripping cylinders run continuously on shop air; this combination conditions the 3/4 in supply, keeps pressure in a low band for gentle handling, and oils the cylinders, with the check valve holding the setting if upstream pressure dips.
A workshop drop serving impact wrenches, grinders and air ratchets: the set cleans and regulates the supply and adds lubricator mist so the tools last, while the psi gauge lets technicians read and set the working pressure at a glance.
Start with the port step: this unit is size 600 with G3/4 ports, the largest step in the GC range, which is the right choice when the line and expected air demand call for 3/4 in piping; smaller sizes 200/300/400 step down in port and physical size. Choose the drain type for the bowls: manual drain (as fitted here) needs an operator to bleed accumulated water, while automatic and differential-pressure drains are available on other codes. The standard element is 40 um; specify the W code if the application needs the 5 um grade. Gauge options cover an embedded square gauge or an external round gauge, with MPa, psi or bar scales - this code carries the round gauge in psi. Thread is PT as standard, with G and NPT as order options; this code is the G-thread version. A bracket is included, and the K code adds a reverse/check valve. Note this is the low-pressure type regulator: the exact adjustment range for the low-pressure version is not published, so confirm it with us. Because flow is published as curves and not 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 GR600-20 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 pressure, working pressure and expected air demand, and we will confirm the sizing against the datasheet on request before you order.
In the code GC60020MLC2GK, the M position sets a manual drain on the bowls, meaning accumulated water is bled off by hand rather than automatically; automatic and differential-pressure drains are available on other codes. The C2 positions fit the external round gauge with a psi scale, and the K code adds a reverse/check valve on the regulator.
