The AirTAC GC300C08MLF2GK AirTAC F.R.L. G1/4 Three-Unit Combination 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 GC300C08MLF2GK is an AirTAC GC three-unit F.R.L. combination: a filter, a regulator and a lubricator delivered as one set for compressed air only. This size-300 configuration is threaded G1/4 and pairs a manual-drain filter fitted with the standard 40 um element, a low-pressure regulator supplied with an embedded square gauge scaled in psi, and an oil-mist lubricator. A reverse/check valve (code K) is fitted and a mounting bracket is included. 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 family is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and with options including automatic or manual drains, a 5 um filter element (code W), gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow for the series is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

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 the cylinders and grippers on a bottling or canning line with filtered, regulated and lubricated air, the low-pressure regulator suiting lines that run at gentle settings and the manual drain suiting a scheduled washdown routine.
Prepares air for a robotic welding cell's clamps and tool changers: the 40 um element removes water and particles ahead of the valves, the regulator holds the circuit setting and the lubricator mists oil for high-cycle cylinders.
Supplies the pusher and gate cylinders on a parcel-sorting conveyor, with the psi-scaled square gauge letting technicians check settings at a glance and the bracket making panel mounting next to the manifold straightforward.
Step up through the sizes - 200, 300, 400 and 600 with ports from 1/8 to 1 inch - so the flow curve covers your demand with margin. The filter drain is your choice of differential-pressure (default), automatic (A) or manual (M); this unit is manual, so draining belongs in routine maintenance. Filter grade is 40 um standard, with 5 um available as code W where finer particulate removal is needed. The embedded square gauge is standard and can be scaled in MPa, psi or bar, with an external round gauge optional. Thread is PT as standard with G and NPT as order options - this unit is G. Brackets are included. Because flow is published as curves rather than a single rating, 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, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the datasheet flow figures and check that size 300 with the G1/4 port is the right step for your line before you order.
L marks the low-pressure regulator type; its exact regulation range is not published, so confirm the setting you need with us before ordering. F2 means the embedded square gauge is scaled in psi (MPa and bar scales are also available). K means a reverse/check valve is fitted. The M earlier in the code is the manual drain on the filter.
