The AirTAC GC600-20G AirTAC F.R.L. Combination, G3/4, 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 5 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC600-20G is a three-piece AirTAC F.R.L. combination: a separate filter, regulator and lubricator assembled as one air-treatment train. This size 600 unit is built around a G3/4 (3/4 in) port with G thread, a 5 um filter element (the finer of the two published grades), an automatic drain that ejects collected condensate without manual attention, and a low-pressure-type regulator. The bowl on the filter stage is aluminium alloy, as is standard at size 600, and the unit ships with a mounting bracket. A round external gauge on a psi scale is fitted, and a reverse/check valve is included to hold downstream pressure if the supply is interrupted. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The medium is compressed air only.
This is a genuine AirTAC part. The GC family is published in sizes 200, 300, 400 and 600, with port sizes from 1/8 in up to 1 in, a choice of differential-pressure, automatic or manual draining, 40 um standard or 5 um (W) filtration, gauge scale options, PT as the standard thread with G and NPT as order options, and standard or low-pressure regulator types. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

Feeding impact wrenches, nutrunners and air ratchets on a final assembly line: the 5 um element protects the tools, the regulator holds a steady low working pressure, and the lubricator mists oil to the tool motors.
Supplying pneumatic cylinders and grippers on a filling or carton-packing conveyor, where the check valve holds the downstream circuit stable during supply dips and the automatic drain keeps condensate out of the valves.
Conditioning the compressed air feeding looms and spinning frames, where continuous running demands clean, lubricated air at a controlled low pressure and the aluminium 600-size bowl handles the plant's main supply drop.
Size and port set the ceiling on flow: the 600 frame with its G3/4 port is the largest published step, so step down to 400/300/200 if your line draws less air. This unit is already configured with the finer 5 um element (code W) - choose it where downstream valves and cylinders are sensitive to fine particulate; the 40 um standard element suits general supply. The automatic drain (code A) suits unattended or hard-to-reach installations; manual and differential-pressure drains are the alternatives on other codes in the family. The low-pressure regulator type (code L) is selected where the circuit runs below the standard regulator's normal band - the exact range for this type is not published, so confirm it with us. The fitted round gauge reads in psi; square embedded gauges and MPa/bar scales are the other published options. Thread is G here; PT is the catalogue standard and NPT is available to order. A bracket is included, and the reverse/check valve (code K) is fitted. Flow is published as curves, not a single rating, so 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. Tell us your line's air demand and working pressure and we will confirm the correct size from the datasheet curves on request before you order.
The L code makes this a low-pressure-type regulator, intended for circuits that run below the standard regulator's normal band; the exact range for this type is not published, so confirm it with us. The A code fits an automatic drain, which ejects condensate from the filter bowl on its own - the right choice where the unit is mounted out of reach or the line runs unattended.
