The AirTAC GC300C08C2G AirTAC F.R.L. Combination, G1/4 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 GC300C08C2G is a three-unit F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator built as one coordinated set, so the downstream air is cleaned of water and particulate, held at a set pressure, and carries a fine oil mist for pneumatic tools and cylinders. This configuration is the 300 size with a 1/4 in port threaded G (BSPP); PT is the standard thread and G or NPT are catalogue options to order. The filter element is the standard 40 um grade, the bowl drains by differential pressure, and the bowls on the 300 size are polycarbonate. The standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), a round gauge scaled in psi is fitted, and the set includes a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600, with larger sizes carrying larger ports and more flow, and with choices of drain type, 5 um (code W) filtration, gauge scale and thread form. Flow is published as curves rather than a single rated figure, so we 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.

Point-of-use conditioning at assembly stations where impact wrenches, nutrunners and air ratchets need clean, moisture-free air held at a stable set pressure with a light oil mist to keep tool motors lubricated through a full shift.
Supplying the case erectors, sorting gates and pusher cylinders along a packaging conveyor, where the filter removes water condensed in the header line, the regulator holds the cylinder pressure steady and the lubricator extends seal life.
Conditioning the air feeding a machining centre's tool-change clamps, pallet clamps and air-blast nozzles, where fluctuating shop air must be filtered, regulated to the clamp specification and lightly oiled for consistent clamping.
Start with the size and port: 300 is the middle step of the 200/300/400/600 range, and the 1/4 in G port here must match your supply plumbing - step up a size if the demand at the point of use is beyond what a 1/4 in line comfortably carries. Choose the drain to suit attendance: differential-pressure (as fitted here) drains automatically while the unit is in service, automatic (code A) drains on a cycle, and manual (code M) needs someone to open it. The 40 um element is the standard grade; specify W for the 5 um element where finer particulate removal matters. Gauge scale is selectable - MPa, psi (fitted here) or bar - and the thread can be PT (standard), G or NPT at order time. A bracket is included; J-code variants omit it.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated number, so send us your flow and pressure requirements and we will confirm the right size from the datasheet before you order.
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 curves rather than a single rated figure, so there is no one l/min or SCFM number we can quote honestly. Tell us your required flow and working pressure and we will confirm the correct size and the datasheet curve figures for your application on request.
Yes. 40 um is the standard grade; the W-code variant of the same series carries a 5 um element for finer particulate removal. Note that the regulator adjustment range depends on the drain type fitted: with the differential-pressure drain fitted here it is 0.15-0.9 MPa (20-130 psi), while a manual-drain version widens the lower end to 0.05 MPa (7 psi).
