The AirTAC GC FRL Unit GC300C08AF1K 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC series is AirTAC's three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled into one air-preparation set. This GC300C08AF1K is the 300 size with PT1/4 (1/4 in.) ports. The filter carries the standard 40 um element, the bowl drains automatically (A suffix), an embedded square pressure gauge with an MPa scale (F1) shows the regulated pressure, and the K suffix adds a reverse (check) valve so air cannot back-flow through the set. The filter and lubricator bowls on the 300 size are polycarbonate.
This is a genuine AirTAC part. The G series spans sizes 200, 300, 400 and 600 with a choice of drain types, 40 um standard or 5 um filter elements, round or square gauges in MPa, psi or bar scales, and PT, G(BSPP) or NPT threads. Maximum working pressure is 1.0 MPa (145 psi) and the operating range is -5 to 70 C, non-freezing. Flow is published as curves rather than one 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: GF300-C0 filter, GR300-C0 regulator and GL300-C0 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 the clamp and squaring actuators of a palletizing station, with the check valve isolating the set from back-flow on a header shared with other machines.
Prepares air for trailer door actuators and dock equipment at a loading bay, where the automatic drain copes with condensate from outdoor supply lines.
Serves a shared maintenance-shop air drop feeding wrenches, blow guns and test rigs, with the 40 um element and regulator covering everyday general-purpose tools.
Size 300 is the mid step of the G series: step up to GC400 or GC600 (larger ports, up to 1 in.) for higher demand, or down to GC200 for compact circuits. The K suffix here fits a reverse (check) valve; order the same code without K if your circuit does not need back-flow protection. The automatic drain gives a regulator adjust range of 0.15-0.9 MPa (20-130 psi); a manual-drain version widens this to 0.05-0.9 MPa. This model uses the standard 40 um element; add the W suffix for the 5 um grade. The F1 gauge is the embedded square type in MPa, with round gauges and psi or bar scales as options, along with PT, G(BSPP) and NPT threads. 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-C0 regulator with a GF300-C0 filter on that branch.
Yes - AirTAC publishes G-series flow as performance curves rather than a single rated figure, so we confirm the exact datasheet curve on request. Send your application details and we will check the 300-size set against your flow requirement before you order.
The K suffix means a reverse (check) valve is fitted, preventing air from flowing backwards through the set - useful on shared drops or where upstream pressure can fall suddenly. Order the identical code without the K if you do not need that protection.
