The AirTAC GC30008LC2K AirTAC F.R.L. Combination, PT1/4, 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 PT1/4" ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC30008LC2K is a three-piece F.R.L. combination that treats compressed air in three separate stages: a filter that removes water and particulate, a pressure regulator, and an oil-mist lubricator. This GC300 unit is built for 1/4 in PT ports and carries a 40 um standard filter element with a differential-pressure drain on the filter bowl. The regulator is the low-pressure type, and the round gauge fitted to this code reads in psi. A reverse/check valve is fitted, and the mounting bracket is included. The filter and lubricator bowls on this size are polycarbonate (PC).
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, PT as the standard thread and G (BSPP) or NPT as order options, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um (W) filtration, gauge scale in MPa, psi or bar, and an optional reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to 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. 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: GF300-08 filter, GR300-08 regulator and GL300-08 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 a machine-tool press line, the GC30008LC2K filters water and swarf-laden air, holds a steady low working pressure for the clamping cylinders, and mists oil to keep the actuator seals and bore surfaces lubricated through every cycle.
Feeding carton formers and case sealers on a packaging line, this three-unit set cleans the plant air, regulates the supply to the low working pressure those machines run at, and lubricates the cylinders and air motors that drive the sealing heads.
On a warehouse sortation conveyor, the combination conditions the air feeding the diverter cylinders: the 40 um element stops particulate reaching the valves, the low-pressure regulator matches the gate operating pressure, and the lubricator keeps the diverters moving freely.
Start with the size and port: GC300 with a PT1/4 port sits in the middle of the range (200/300/400/600), and the right step depends on the air consumption of the downstream circuit - move up a size for higher demand rather than undersizing the combination. Choose the drain type where it applies: differential-pressure (as coded here) drains on pressure differential, automatic (A) drains without attention, and manual (M) drains only when operated. Choose 40 um for general air preparation or 5 um (code W) for finer particulate removal. The gauge scale can be MPa, psi or bar; this code carries a round psi gauge. Thread is PT as standard, with G (BSPP) and NPT available to order; the low-pressure (L) regulator type is the correct choice where the working pressure sits below the standard regulator's range, and the K code adds a reverse/check valve. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. 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 GR300-08 regulator with a GF300-08 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote one number here. Tell us your application and we will confirm the flow and datasheet figures for the GC300 at 1/4 in PT on request before you order.
In the code GC30008LC2K, the L marks the low-pressure regulator type, which is the right choice when the working pressure sits below the standard regulator's range - confirm the exact adjustment range with us, as it is not published as a single figure. The C2 gives a round gauge reading in psi (MPa and bar scales are also available), and the K means a reverse/check valve is fitted to hold downstream pressure if the supply drops.
