The AirTAC GC300C08MC2GK 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 assembled into one unit. This GC300C08MC2GK is built for 1/4 in (G1/4) lines and carries a manual drain on the filter bowl, a 40 um filter element, a round pressure gauge reading in psi, a reverse/check valve and a mounting bracket. It removes water and particulate from compressed air, holds a set downstream pressure, and adds oil mist for downstream air tools.
This is a genuine AirTAC part. The GC range spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options include automatic or differential-pressure drains, a 5 um element (code W), square embedded or external round gauges with MPa, psi or bar scales, and G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm datasheet figures for your application.

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.

Clean, regulated and lubricated air feeding pneumatic clamps and tool-change cylinders on a machining centre, with the check valve holding downstream pressure through upstream dips.
Supply air for the cylinders and air-driven diverters on a carton-forming and sealing conveyor, where the filter keeps moisture out of the valve bank and the regulator holds a steady setting.
Point-of-use air preparation for impact wrenches, air ratchets and riveters on an assembly line, where the oil-mist lubricator keeps the tools running smoothly through the shift.
Size 300 with a G1/4 port sits in the middle of the GC range: step up to 400 or 600 for larger ports and more flow, or down to 200 for compact lines, matching the size step to the flow your circuit needs. The manual drain (code M) is opened by hand, so choose the automatic or differential-pressure drain option where the unit is hard to reach. The 40 um element is the standard grade; specify W for the 5 um element where finer filtration is required. The round gauge on this unit reads psi; embedded square gauges and MPa or bar scales are alternatives. G thread is an order option - PT is the standard thread. Regulation range for this configuration is 0.05-0.9 MPa (7-130 psi).
Flow is published as curves, not a single rating, so send us your flow requirement and we will confirm sizing against 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 line pressure and the flow your circuit needs, and we will confirm the correct size against the datasheet before you order.
The M in the code means the filter bowl drain is opened by hand, which suits units mounted where an operator passes regularly. If the unit will be hard to reach, the same GC300 size is available with an automatic drain (code A) or the differential-pressure drain that is the catalogue default.
