The AirTAC GC40015ALC2GK AirTAC F.R.L. Combination, G1/2, Low-Press 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 PT1/2" ports, a 40 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC40015ALC2GK is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one air-treatment set. This size 400 unit carries a G1/2 (BSPP) port, and the configuration is fully decoded from the code: the filter has an automatic drain and the standard 40 um filtering element, the regulator is the low-pressure type, and a round gauge scaled in psi is fitted so line pressure can be read and set directly. The reverse/check valve (code K) is fitted, and the mounting bracket is included. The filter and lubricator bowls are polycarbonate (PC) on this size.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with a choice of ports, drain types, filter grades (40 um standard, 5 um optional), gauge styles and scales, and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so we confirm the datasheet and sizing figures on request 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. 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.
| GC400 | G-series F.R.L. combination, 400 body — sets the port range. |
|---|---|
| 15 | Port size PT1/2". This body offers 10 = PT3/8", 15 = PT1/2". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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: GF400-15 filter, GR400-15 regulator and GL400-15 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 row of pneumatic nutrunners and clamping fixtures at an assembly station: the filter strips water and 40 um particulate from the shop-air drop, the low-pressure regulator holds a steady setting for the tools, and the lubricator carries a fine oil mist to keep the tool motors running through a full shift.
Supplying the cylinders and vacuum generators on a carton-forming and case-taping line, where the automatic drain clears condensate from the bowl without an operator stopping the machine, the regulator keeps actuator speed consistent, and the lubricator mists the air feeding high-cycle cylinders.
Treating the air upstream of a small pneumatic press or workholding fixture: clean, regulated and lubricated air protects the valve stack and cylinder seals, the fitted psi gauge lets the setter read and dial in the clamping pressure, and the included bracket mounts the set beside the machine.
Start with the port and size: the GC series steps through sizes 200, 300, 400 and 600, and the size you pick sets both the port (this model is 1/2 in) and the flow capacity of the set, so match the size step against the air demand of the circuit it feeds. Then set the options that matter to your line: drain type on the filter (automatic, as fitted here, versus manual or differential-pressure), filter grade (40 um standard, 5 um with code W for finer particulate), gauge style and scale (this unit has a round gauge in psi; square embedded gauges and MPa/bar scales are available), and thread family (PT is the standard, with G and NPT as orderable options).
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. Ask us to confirm the datasheet and check the 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 GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated number, so no rated flow figure is quoted here. We can confirm the datasheet and check the curves against your actual air demand before you order - just ask, and send us your required flow and working pressure.
The A in the code means the filter bowl drains condensate automatically, which suits unattended or high-condensate installations. The alternates in the series are manual drain (code M, you drain it by hand) and differential-pressure drain (blank, the default). The regulator on this unit is the low-pressure type; its exact adjustment range is not published on the sheet we work from, so we confirm it on request.
