The AirTAC GC60020C2WK AirTAC F.R.L. Combination, PT3/4 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 5 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC600 is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one air-treatment set. This configuration, GC60020C2WK, is the 600 size with a PT3/4 (3/4 in) PT connection. The filter element is the fine 5 um grade (code W) with a differential-pressure drain, and because this is the 600 size the filter bowl is aluminium alloy. The regulator is the standard type with a round external gauge reading in psi, and a reverse/check valve (code K) is fitted so downstream pressure is held if the upstream supply is lost.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include thread type (PT standard, G and NPT to order), drain type, filter grade and gauge scale. Flow is published as curves rather than a single rated figure, so ask us and we will 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.

Feeding spray-booth and paint-line air drops where the 5 um element, regulated pressure and oil misting protect finish quality on vehicle bodies.
Treating the air feeding case sealers, tapers and wrapping machines on a packaging conveyor line, with the check valve holding downstream pressure during supply dips.
Conditioning the shop-air feed to CNC machining centres and pneumatic clamping fixtures, where clean, regulated, lightly lubricated air keeps tool changers and actuators working.
Size and port are the first choice: the 600 size carries the largest ports in the GC range, and this unit is already set at PT3/4, so match it to your line's connection and required air demand. The filter grade here is the fine 5 um element (code W); the standard element is 40 um, so choose 5 um only where downstream equipment needs the finer air. Drain is the differential-pressure type, which bleeds the bowl automatically as pressure drops - an automatic-drain or manual-drain bowl can be ordered instead. The gauge is an external round type reading in psi; embedded square gauges and MPa or bar scales are the other catalogue options. Thread is PT as standard, with G (BSPP) and NPT available to order, and a mounting bracket is included.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated number, so send us your application details and we will confirm the correct size against the datasheet before you order.
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 performance curves rather than a single rated figure, so we do not quote one number. Tell us your application and air demand and we will confirm the datasheet flow curves for this 600-size, PT3/4 unit on request.
The W in the code GC60020C2WK selects the optional fine 5 um element; the catalogue standard for the GC filter section is 40 um. Choose 5 um where downstream valves, cylinders or processes need finer filtration, and note the drain on this unit is the differential-pressure type, which drains the aluminium alloy bowl automatically as pressure drops.
