The AirTAC GC30008MC2GK AirTAC F.R.L. Combination 1/4 in G 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC30008MC2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This configuration is built around a 300 size body with a G1/4 (1/4 in) G-thread port. The filter section carries the standard 40 um element with a manual drain, so an operator drains collected water by hand on a routine. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and a round psi gauge is fitted so the set downstream pressure can be read directly. A reverse/check valve is fitted, and the mounting bracket is included.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with a choice of PT, G or NPT thread, automatic, manual or differential-pressure drains, 40 um or 5 um (W) filter grades, and gauge scale options. Flow is published by AirTAC as curves rather than a single rated figure, so we confirm the datasheet and sizing 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 0.05 - 0.9 MPa (7 - 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.
| GC300 | G-series F.R.L. combination, 300 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Feeds filtered, regulated and lubricated air to spray guns and air-driven agitators at a paint line, with the 40 um element catching water and pipe scale before it reaches the finish.
Serves the pneumatic cylinders on a carton-forming and sealing conveyor, holding a steady regulated pressure while the lubricator keeps seal and valve wear down across shifts.
Supplies impact wrenches and air ratchets at a maintenance bench, with the check valve holding the set pressure against backflow and the psi gauge giving the technician a direct read.
Start with the port and size step: this unit is 300 size with a 1/4 in port; step up to 400 or 600 if your line needs more flow capacity, or down to 200 for compact drops. Drain choice matters in practice: manual drain (as fitted here) puts water removal on a maintenance routine, while automatic or differential-pressure drains handle it continuously. Filter grade is 40 um standard; specify the W option for 5 um if downstream equipment needs finer filtration. Gauge scale can be MPa, psi or bar, and the thread can be ordered as PT (standard), G or NPT.
Because AirTAC publishes flow only as curves and not as a single rated figure, ask us to confirm sizing against your actual air consumption 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 only as performance curves, not as a single rated number, so we do not quote a figure here. Tell us your application and air demand and we will confirm the datasheet flow curves and sizing for this 300 size, 1/4 in unit on request.
The M in the code GC30008MC2GK specifies a manual drain: collected water in the filter bowl is released by hand as part of a maintenance routine. If you prefer the bowl to discharge automatically, the same GC300 combination can be ordered with an automatic (A) or differential-pressure (blank) drain code.
