The AirTAC GC30008AC2GK AirTAC F.R.L. Combination, G1/4, Auto Drain 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 automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set, so filtration, regulation and lubrication are each handled by their own unit. This GC30008AC2GK is built for G1/4 (BSPP) lines. The filter bowl drains automatically, the element is the standard 40 um grade, and the polycarbonate bowls suit the 300 size (only the 600 size uses aluminium alloy). The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, a round gauge with a psi scale is fitted, a reverse/check valve is installed, and a mounting bracket is included.
This is a genuine AirTAC part. The GC range spans sizes 200, 300, 400 and 600, with port sizes from 1/8 to 1 inch and PT (standard), G or NPT threads to order, plus drain, filter-grade, gauge-scale and reverse-valve options. Because AirTAC publishes flow as curves rather than a single rated figure, we confirm the datasheet and flow 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.
| 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". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 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.

Feeding spray guns and air-fed respirators on a refinish line, where filtered, regulated and lubricated air supports consistent finish quality and smooth gun operation.
Supplying the cylinders and valves on carton sealers and case packers, with the automatic drain clearing condensate before it reaches the actuators downstream.
Powering pneumatic clamps and tool-change cylinders on machining centres, where the regulator holds the set pressure and the lubricator mists the moving parts.
Choose the size by the port and flow your line needs: 200, 300, 400 or 600, stepping up as air demand grows - this unit is size 300 with G1/4 ports. Pick the drain for the filter bowl: automatic (as here), manual, or the differential-pressure default. The element is 40 um as standard; order the W variant for 5 um if downstream equipment needs finer filtration. Gauge scale can be MPa, psi or bar (this one is psi), and the thread can be PT (standard), G or NPT. A reverse/check valve and bracket options round out the code. 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 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 flow and datasheet figures for this exact model on request.
GC is the three-unit F.R.L. family, 300 is the size, 08 is the 1/4 in port and G is the BSPP thread. A sets the automatic drain, the blank filter position is the 40 um element, C2 is the external round gauge with a psi scale (1 is MPa, 3 is bar), K shows a reverse/check valve is fitted, and the blank bracket position means a bracket is included.
