The AirTAC GC60020LF2K 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 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC60020LF2K is an AirTAC GC600 three-unit F.R.L. combination: a separate filter, regulator and lubricator built as one air-treatment train. It removes water and particulate from compressed air down to 40 um, holds downstream pressure with the low-pressure type regulator, and meters oil mist into the line to lubricate cylinders and air tools. This 600-size unit carries PT3/4 ports, a differential-pressure drain on the filter bowl, an embedded square gauge scaled in psi, and a reverse/check valve. At size 600 the bowls are aluminium alloy.
This is a genuine AirTAC part. The GC series spans 200, 300, 400 and 600 sizes with ports from 1/8 to 1 inch, and options including automatic or manual drains, a 5 um filter element (code W), gauge scales in MPa, psi or bar, and G or NPT threads in place of the PT standard. Rated flow for the GC600 is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing for your application.

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.

A stamping or forming shop running pneumatic presses needs one treated air point that cleans the supply, holds a steady set pressure and feeds oil mist to the cylinders. This three-unit combination does all three jobs at a 3/4 inch take-off.
Packaging machines driven by air cylinders run all shift, so the supply air has to stay dry, filtered and regulated while the lubricator keeps seal-less cylinders and actuators working smoothly. One GC unit per line drop covers it.
A bench of impact wrenches, nut runners and air ratchets draws heavily on the shop air ring. A 3/4 inch F.R.L. at the tool board filters scale and water, regulates the working pressure and carries oil mist out to the tools.
Pick the GC size by the port and flow your line needs: the 200 to 600 steps run from 1/8 up to 1 inch ports, and this 600 unit sits at the 3/4 inch PT end of the range. The code also fixes the drain type (differential-pressure here, with automatic and manual as options), the filter grade (40 um standard, 5 um with W), the gauge scale (psi on this unit; MPa and bar available) and the thread (PT standard, G or NPT to order). Flow is published as curves, not a single rating, so send us your air demand 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 GC-series flow as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the datasheet flow for this 3/4 inch unit on request.
L marks the low-pressure type regulator, for applications that set pressure below the standard unit's range. The exact adjustment range for the low-pressure type is not published in the catalogue, so confirm it with us against the datasheet before ordering.
