The AirTAC GC30010ALF2G 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 GC30010ALF2G is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply unit. This configuration is the size 300 (GC300) unit with a 3/8 in port on G (BSPP) thread, a 40 um standard filter element, an automatic drain on the filter bowl, a low-pressure type regulator, and a fitted embedded square gauge scaled in psi. The automatic drain expels collected condensate without manual attention, which suits duty where the unit is not checked daily, and the lubricator meters oil mist into the downstream air for tools and cylinders that need it.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type, 5 um or 40 um filtration, gauge scale, thread form (PT standard, G and NPT to order) and reverse/check valve. Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the datasheet 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

A filtered, regulated and lubricated supply point feeding air tools, impact wrenches and hoists at a workshop or plant air drop, where one three-piece unit conditions the air for everything hung on that line.
Conditioning the air feeding pneumatic cylinders on a packaging or conveyor line, where clean regulated pressure drives the motion and oil mist lubricates the seals and moving surfaces over long shift runs.
A low-pressure type regulator makes this unit a fit for process or laboratory air skids that operate well below standard plant pressure, with the psi-scaled gauge giving a direct local reading at the skid.
Size and port set the air capacity of the unit: the 300 size with a 3/8 in port sits mid-range in the GC line, one step above the 200/1/4 in class and below the 400 and 600 sizes. Match the size step to your required flow rather than to pipe size alone, and ask us to confirm sizing against the published flow curves before ordering. Other decodable choices on this series: drain type (this unit is automatic; manual and differential-pressure drains exist), filter grade (40 um standard here, 5 um with code W), gauge scale (this unit is square, psi; MPa and bar scales and an external round gauge are options), thread form (G here; PT is the standard thread and NPT is an order option), and the low-pressure regulator type chosen for this code. The mounting bracket is included. Note that the exact regulation range of the low-pressure type is not published in our sheet; we will confirm it 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 GR300-10 regulator with a GF300-10 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote a number on the page. Tell us your operating pressure and air demand and we will confirm the datasheet flow figures for this exact unit on request before you order.
The A in the code GC30010ALF2G selects the automatic drain, which discharges condensate from the filter bowl by itself instead of waiting for a manual bleed. Manual and differential-pressure drain variants exist in the same GC300 series if your installation prefers them; the choice is made in the model code, not by adjustment.
