The AirTAC GC300C10MF2GK AirTAC F.R.L. Combination, G3/8 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 GC300C10MF2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one conditioning set for compressed air. This 300-size unit is configured for G3/8 (BSPP) ports, with a manual-drain filter bowl, the standard 40 um filtration grade, an embedded square gauge reading in psi, a reverse/check valve fitted on the regulator, and a mounting bracket included. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi) in this manual-drain configuration, and the set handles a maximum inlet pressure of 1.0 MPa (145 psi) at temperatures from -5 to 70 C (non-freezing). On the 300 size, the filter and lubricator bowls are PC (polycarbonate); only the 600 size uses aluminium alloy bowls.
This is a genuine AirTAC part. The GC series is available in 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, and with choices of thread (PT standard, G or NPT to order), drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um with code W), gauge scale (MPa, psi or bar) and check-valve option. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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-C1 filter, GR300-C1 regulator and GL300-C1 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.

Point-of-use conditioning at paint booth air drops: the filter removes water and particulate before the regulator holds a stable set pressure for spray guns, while the lubricator mists oil to the air tools on the line.
Feeding clamps, tool-change cylinders and air-powered fixtures on CNC machining centres, where one three-unit set at the machine inlet filters the supply, regulates clamp pressure and lubricates downstream actuation.
Conditioning the air feeding carton-forming and case-sealing machinery on a packaging line: clean, regulated and lubricated air for the pneumatic cylinders, grippers and sealing heads along the conveyor.
Start with the size and port: the GC series steps through 200, 300, 400 and 600, each with a larger port and higher flow capacity, so match the step to the air demand of the circuit rather than oversizing blindly. Because flow is published as curves and not as a single rating, ask us to confirm sizing against your application before ordering. Then choose the decodable options: drain type (manual for this code, or automatic or differential-pressure), filter grade (40 um standard here, 5 um with code W for finer filtration), gauge scale (this unit carries an embedded square gauge in psi; MPa and bar scales and an external round gauge are available), thread (PT is the standard; G and NPT are order options), and whether a reverse/check valve is required. A bracket is included with this configuration.
For this exact code, the G3/8 thread, manual drain, 40 um grade, psi gauge and check valve are fixed by the model number. If any of those choices does not suit the installation, select the alternative code within GC300 rather than modifying the unit, and we will confirm the corresponding datasheet figures on request.
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-C1 regulator with a GF300-C1 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 rated flow, Cv or SCFM number for this unit. Tell us your application and required air demand and we will confirm the flow and sizing figures from the datasheet on request before you order.
The M in the model code specifies a manual-drain filter bowl, which means condensate is drained by hand rather than automatically. The GC series also offers automatic and differential-pressure drains as alternative codes. Note that the regulator adjustment range depends on the drain type: with a manual drain it is 0.05-0.9 MPa (7-130 psi), while automatic and differential-pressure drain versions are 0.15-0.9 MPa (20-130 psi).
