The AirTAC GC30010AF2GK 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 automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30010AF2GK is an AirTAC GC three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one prepared-air station. It filters water and particulate from compressed air down to 40 um, regulates downstream pressure within a 0.15-0.9 MPa (20-130 psi) adjustment range, and adds oil-mist lubrication for downstream air tools and actuators. This configuration is the 300 size with G3/8 ports, an automatic drain that expels collected condensate without manual attention, a fitted embedded square gauge reading in psi, 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); the bowls on this size are polycarbonate (PC).
This is a genuine AirTAC part. The GC series is available in 200, 300, 400 and 600 sizes with port sizes from 1/8" to 1", and with options including manual or differential-pressure drains, a 5 um filter grade (code W), gauge scale in MPa, psi or bar, and G, PT or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us and we will 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: GF300-10 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 spray guns and air-assisted applicators on a finishing line, where the filter removes water and pipe-scale, the regulator holds a steady gun pressure and the lubricator mists oil to the gun's air motor.
Conditioning the air feeding pneumatic cylinders and grippers on a carton or shrink-wrap packaging machine, keeping condensate and particles out of valves while holding consistent cylinder pressure.
A wall-mounted drop at a maintenance or assembly bench supplying impact wrenches, air ratchets and die grinders, with the lubricator extending tool life and the psi gauge letting operators set and check line pressure.
Start with the size and port: the 300 size carries 3/8" ports here, and stepping up to 400 or 600 increases both port and flow capacity, so match the size step to the air demand of the line rather than to the pipe alone. This unit already carries the automatic drain; if your installation is visited regularly or the bowl sits where an auto drain cannot vent, a manual or differential-pressure drain variant can be specified instead. The 40 um standard filter grade suits general plant air; choose the 5 um (W) grade where finer protection is needed. The fitted square gauge reads in psi, and MPa or bar scales plus an external round gauge are alternatives. Thread here is G (BSPP); PT is the standard catalogue thread and NPT is also an orderable option.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application's air demand and we will confirm the correct size against the datasheet curves 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 state a flow number here. Send us your application's air demand and operating pressure and we will confirm the sizing against the datasheet curves on request before you order.
The A in the code means the filter bowl drains itself automatically, discharging collected condensate without anyone opening the drain - useful on unattended or hard-to-reach installations. Manual and differential-pressure drain variants are available if you prefer. The K code also means a reverse/check valve is fitted, and the F2 gauge reads in psi.
