The AirTAC GC30010MC2GK 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 PT3/8" ports, a 40 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC30010MC2GK is an AirTAC GC300 three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply unit. This configuration is built for 3/8 in lines with G thread, carries the standard 40 um filter element, and uses a manual drain on the filter bowl, so condensate is released by an operator rather than automatically. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and this unit is fitted with an external round gauge reading in psi plus a reverse/check valve. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The filter bowl on this 300 size is polycarbonate (PC).
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with a choice of ports, threads, drain types, filter grades (40 um standard, 5 um optional) and gauge scales. Published flow data takes the form of curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application before you order.

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 0.05 - 0.9 MPa (7 - 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: GF300-10 filter, GR300-10 regulator and GL300-10 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 a workshop pneumatic press: the filter strips water and chips from the shop air, the regulator holds a steady working pressure on the gauge, and the lubricator oils the press cylinder seals through a 3/8 in supply line.
Supplying impact wrenches, nutrunners and grinders at an assembly bench: clean, regulated and lubricated air keeps the tools running consistently through a shift, with the psi gauge letting operators verify the set pressure at a glance.
Air preparation for conveyor diverters and packaging-machine cylinders: the 40 um filter protects valve spools, the regulator pins the actuation pressure, and the oil mist extends cylinder and valve life on a manual-drain drop leg.
Start with the size and port: 300 is the middle step of the GC range (200/300/400/600), and this unit takes a 3/8 in port, so match it against the line size and the air demand of the downstream cylinders and tools - we can confirm the flow curves against your consumption before you commit. The manual drain on this unit suits installations where an operator walks the line; choose the automatic or differential-pressure drain variant instead for unattended duty. The 40 um element is the standard grade for general plant air; specify the 5 um (W) option where finer particulate removal matters. The fitted round gauge reads in psi; MPa and bar scales are also available. Thread is G here, with PT as the standard and G/NPT as order options. Note the fitted reverse/check valve holds downstream settings if upstream pressure is lost. Flow is published as curves, not a single rating, so 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 GR300-10 regulator with a GF300-10 filter on that branch.
AirTAC publishes flow for the GC300 as curves, not as a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Send us your line pressure and the air consumption of the equipment downstream, and we will confirm the datasheet flow curves for this exact model before you order.
K means a reverse/check valve is fitted. If upstream pressure is lost or removed, the valve holds the regulated downstream circuit so set pressures and the lubricator oil film are not lost. Units without the K code do not have this valve.
