The AirTAC GC30010AC2GK AirTAC F.R.L. Combination, G3/8, Auto Drain 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 automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30010AC2GK is a three-piece AirTAC GC-series F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled for 3/8 in (G3/8) compressed-air lines. The filter element is the standard 40 um grade and the bowl is fitted with an automatic drain, so collected water is expelled without manual attention; the bowl on this 300 size is polycarbonate (PC). The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the code confirms a round pressure gauge with a psi scale, a reverse/check valve, and an included mounting bracket. 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 offered in sizes 200, 300, 400 and 600 with matching port sizes, a choice of differential-pressure, automatic or manual drains, a 40 um standard or 5 um (code W) filter grade, gauge style and scale options, and PT, G or NPT threads. Rated flow for this combination is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing 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: GF300-10 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.

Feeds clean, regulated and lubricated air to the tool-changer, clamps and pneumatic cylinders on a machining centre, with the automatic drain handling condensate during unattended shifts.
Conditions the air at each drop on an assembly line so water and particulates are removed, pressure is held steady for actuators, and a fine oil mist reaches air tools and cylinders.
Supplies treated air to the diverters, grippers and seal cylinders on a packaging line, with the check valve helping hold the set circuit pressure and the psi gauge giving operators a local reading.
Start with the port and size: the 300 size carries the 3/8 in port decoded here, and larger sizes give larger ports and more flow - step up if your line demand is near the top of a size's curve. Choose the drain to suit access: automatic (as coded here) suits unattended duty, manual suits periodic checks, and differential-pressure is the default. Filter grade is 40 um standard; specify 5 um (W) where downstream valves need finer filtration. Gauge options are an embedded square gauge or an external round gauge with MPa, psi or bar scales - this unit has a round psi gauge. Threads are PT as standard with G and NPT as orderable options; brackets are included on this code.
Flow for GC combinations is published as curves, not a single rated number, so send us your line pressure and air demand 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 GR300-10 regulator with a GF300-10 filter on that branch.
AirTAC publishes flow for the GC series as performance curves rather than a single rated figure, so we do not quote one number. Send us your line pressure and air demand and we will confirm the flow and sizing against the datasheet on request.
The A in the code GC30010AC2GK specifies an automatic drain on the filter bowl, so condensate is expelled without operator attention. The GC series is also available with a manual drain (M) or the default differential-pressure drain, and the filter grade can be changed from the standard 40 um to 5 um with the W code.
