The AirTAC GC300C08MLF2WK AirTAC F.R.L. Combination, PT1/4 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 GC300C08MLF2WK is a genuine AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one complete air-preparation set. This GC300 configuration is sized for 1/4 in (PT) ports and carries a 5 um filter element (the finer of the two published grades) with a manual drain, so condensate is released by operator action rather than automatically. The regulator is the low-pressure type and is fitted with an embedded square gauge reading in psi; a reverse/check valve (code K) is fitted, and a mounting bracket is included. Metal bowls are used on this unit, with a maximum working (inlet) pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GC300 size class. Across the GC line the published choices include port sizes from 1/8 in to 1 in, PT, G (BSPP) or NPT threads, manual, automatic or differential-pressure drains, 40 um standard or 5 um (W) filter elements, standard or low-pressure regulators, and square or round gauges scaled in MPa, psi or bar. Flow for this series is published as curves rather than a single rated figure, so contact 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 filtered, regulated and lubricated air to the tool-clamp and pallet-changer circuits of a small CNC machining centre, where the 5 um element helps keep water and particulate out of the clamping valves.
Supplies prepared air to the cylinders on a carton-taping and flap-folding station, with the lubricator metering oil mist to keep the sealing-head actuators working through long shifts.
Installed at the air inlet of weaving or spinning machinery, where the low-pressure regulator suits circuits that run at reduced pressure and the manual drain suits a supervised maintenance routine.
Start with the port step: this unit is the 300 size with 1/4 in PT ports, so match it to the air line diameter at the point of use; larger sizes (up to 600) carry larger ports and sit on higher-flow circuits. Because flow in this series is published as curves and not as a single rated number, ask us to confirm sizing against your application before ordering. The decodable choices on this code are: manual drain (you drain the bowls by hand on a schedule you control), 5 um filtration instead of the 40 um standard element, the low-pressure regulator type, a square gauge scaled in psi, a fitted reverse/check valve, and an included mounting bracket. Thread is PT as standard; G (BSPP) and NPT are catalogue options to order. If your compressor or process needs a different drain style, gauge scale or thread, those exist as orderable variants in the same series.
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 this series as curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your application and line conditions and we will confirm the datasheet flow figures for this unit on request before you order.
The L in the code means the regulator is the low-pressure type rather than the standard type; the exact adjustment range for the low-pressure variant is not published in our data, so we will confirm it on request. The M in the code means the filter bowl has a manual drain: condensate is released by hand during maintenance, unlike the automatic or differential-pressure drain options available in the same series.
