The AirTAC GC FRL Unit GC300C08F1K 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 AirTAC GC series is a three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator ordered and installed as one set. This configuration is size 300 with a PT1/4 (1/4 inch) port, differential-pressure drain on the filter bowl, standard 40 um filtration, an embedded square MPa gauge on the regulator, and a reverse (check) valve fitted so downstream pressure is held if the supply drops. The set filters water and particulate, regulates pressure and meters oil mist to downstream equipment, with a maximum working pressure of 1.0 MPa (145 psi) and an operating range of -5 to 70 C (non-freezing). The 300-size bowls are PC (polycarbonate).
This is a genuine AirTAC part. The GC combination is available in sizes 200, 300, 400 and 600 with a choice of port, thread (PT standard; G and NPT as catalogue options), drain type, filter grade, gauge style and scale, and the K check-valve option. Flow is published as curves rather than a single rated figure; we confirm the datasheet and sizing 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 filtered, regulated and lubricated air to the tool-changer and clamping cylinders on a machining center, with the check valve holding clamp pressure if the shop supply dips mid-cycle.
Conditions the air feeding transfer cylinders and diverters on a carton packaging conveyor, keeping moisture and debris out of the valves while oil mist lubricates the seals.
A point-of-use F.R.L. set at a bench pneumatic press, giving the operator a visible MPa gauge to set working pressure and a check valve that maintains the set pressure during supply fluctuations.
Size 300 with a PT1/4 port suits circuits plumbed at 1/4 inch; step down to size 200 for compact drops or up to 400/600 for larger porting and higher flow demand. The differential-pressure drain flushes the filter bowl automatically as the pressure differential builds, so no daily manual draining is needed, and the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi). Standard filtration is 40 um; specify W for 5 um where finer protection matters. The square MPa gauge is embedded in the regulator, with round external gauges and psi/bar scales available to order. Thread is PT as standard, with G (BSPP) and NPT as catalogue options. 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.
AirTAC publishes flow for the GC series as performance curves, not a single rated figure, so we do not quote a number on this page. Send us your required flow and working pressure and we will confirm the datasheet curve and check that the size 300 / PT1/4 configuration suits your application.
K fits a reverse (check) valve, so air downstream of the set is held if the upstream supply pressure falls. That protects circuits such as clamps or holding cylinders from losing position during a supply dip. If you do not need that function, the same set is available without the K option.
