The AirTAC GC300C08MLC2WG 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 GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator built together as one supply unit that cleans, regulates and oil-mist lubricates compressed air. This GC300C08MLC2WG is the 300 size with a G1/4 (BSPP) port. It is the low-pressure regulator type, fitted with a round gauge reading in psi, a 5 um filter element, a manual drain on the metal bowl, and it includes a mounting bracket. Maximum working (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 family is offered in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, and with real choices at order time: drain type (differential-pressure standard, automatic or manual), filter grade (40 um standard or 5 um with code W), gauge style and scale (MPa, psi or bar), thread (PT as the standard, G and NPT as order options) and an optional reverse/check valve. Flow is published as curves rather than a single rating, so we confirm flow and other datasheet figures 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.

One supply point feeding the wrapper and carton-sealing cylinders on a packaging line: the 5 um element strips water and fine dirt before the valve stack, the regulator holds the circuit pressure and the lubricator mists oil to the cylinders.
Feeding a clamping or holding circuit on a machining cell that runs at reduced pressure - this unit is the low-pressure regulator type, with the filter protecting the fixture valves and the lubricator conditioning the clamp cylinder seals.
Supplying vane air motors along a conveyor run, where filtered and regulated air keeps the motors running cleanly and the oil-mist lubricator carries lubrication to bearings and vanes that cannot be greased in place.
Step through the 200/300/400/600 sizes to match the port and flow your circuit needs - the 300 size here carries a 1/4 in port. Drain type is a real decision: this unit has a manual drain, which suits positions that are bled down on a routine; automatic or differential-pressure drains suit unattended installations. The 5 um element (code W) is the finer option against the 40 um standard, useful where fine particulate must be kept out of downstream valves. The round gauge on this unit reads in psi; the embedded square gauge and MPa or bar scales are the alternatives. Thread is G (BSPP) on this code, while PT is the standard offering and G/NPT are order 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 curves rather than a single rated figure, so we do not quote a number on the page. Send us your line pressure and air consumption and we will confirm the sizing from the datasheet on request before you order.
This configuration carries code M, meaning the filter bowl is drained by hand at intervals - a good fit where the unit is checked as part of a routine. If the unit will sit unattended, ask about the automatic or differential-pressure drain variants when ordering. Note also that this is the low-pressure regulator type and its exact adjustment range is not published, so confirm it with us.
