The AirTAC GC300C08MLF2WG AirTAC F.R.L. Combo, G1/4, 5 um Filter 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-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, set up as one coordinated air-preparation package for a compressed-air circuit. This GC300C08MLF2WG is the size 300 unit with a 1/4 in port on G (BSPP) thread, so it sits directly in a 1/4 in line and conditions the air three ways: the filter element is the fine 5 um grade (code W) for water and particulate removal, the manual-drain bowl is emptied by hand, and the low-pressure-type regulator holds a reduced downstream pressure. A square pressure gauge reading in psi is fitted, and the mounting bracket is included.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, and options across the range include automatic or differential-pressure drains, a 40 um standard element, alternative gauge scales (MPa, psi or bar) and PT or NPT thread as order options. Flow is published by AirTAC as curves rather than a single rated figure, so ask us to 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.

Feeding filtered, regulated and lubricated air to the cylinder and valve bank cluster on a carton-forming packaging machine, where the 5 um element helps keep pilot valves clean and the lubricator carries oil mist to the actuators.
Point-of-use preparation at an assembly bench: the unit filters and regulates the supply before it reaches air screwdrivers and clamping fixtures, with the psi gauge giving the operator a local pressure reference.
Conditioning the air for pop-up divertors and stopper cylinders on a distribution conveyor line, where the low-pressure-type regulator suits circuits run at reduced pressure and the manual drain fits a maintenance round.
Start with the port step: this unit is size 300 with a 1/4 in G-threaded port, and the GC range steps up through sizes 400 and 600 (larger ports, more flow) or down to size 200 if your line is smaller - match the size to the flow your circuit needs rather than to the pipe alone. The drain here is manual, meaning someone bleeds the bowl on a routine; if nobody will do that reliably, the automatic or differential-pressure drain options are worth considering. The 5 um element (code W) is the finer choice over the 40 um standard - pick it where downstream valves and instruments want cleaner air. The fitted square gauge reads in psi; MPa and bar scales are alternatives. Thread is G (BSPP) on this code, with PT (standard) and NPT available as order options, and a bracket is included.
One honest note before you order: AirTAC publishes flow for these units as curves, not as a single rated number, so send us your application details and we will confirm the sizing and the datasheet figures with you before you commit.
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 does not publish a single rated flow figure for the GC units - flow is given as performance curves instead. We do not want to quote you a number the catalogue does not state, so tell us your application and we will confirm the flow and the full datasheet figures on request before you order.
The M in the code is the drain option: the bowl that collects water and particles is emptied by hand rather than by an automatic or differential-pressure mechanism. It is a real decode choice on the GC family - manual drain suits installations on a maintenance round, while the automatic and differential-pressure drain options suit unattended lines. Note that with a manual drain the regulator adjustment range starts lower than with the other drain types, and we can confirm the exact figures on request.
