The AirTAC GC400-10 AirTAC F.R.L. Combination, G3/8, Low-Pressure 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 5 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC400-10 is a three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one air-preparation set. This configuration is the size 400 unit with a G3/8 (BSPP) port, a 5 um filter element for finer water and particulate removal, a differential-pressure drain on the filter bowl, and a low-pressure type regulator fitted with an embedded square gauge scaled in psi. The bowls are polycarbonate, and the set includes a mounting bracket.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with a choice of drain type, filter grade (40 um standard, 5 um optional), gauge scale (MPa, psi or bar), and PT, G or NPT thread. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

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. |
|---|---|
| 10 | Port size PT3/8". This body offers 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure 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). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 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. |

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: GF400-10 filter, GR400-10 regulator and GL400-10 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 filtered, regulated and lubricated air to a row of pneumatic assembly tools and cylinders on a plant air drop, with the 5 um element protecting downstream valves from fine contamination.
Supplies conditioned air to packaging machinery actuators and gripper cylinders, where the lubricator keeps seals and moving parts oiled through continuous shift running.
Prepares air for circuits that run at reduced working pressure, with the low-pressure regulator trimmed at the square psi gauge for spray equipment or pneumatic clamping fixtures.
Choose the size and port step against the air demand of the circuit: this unit is size 400 with a G3/8 port, one step up from the 300 series. The 5 um element (code W) suits applications needing finer filtration than the 40 um standard element; the differential-pressure drain bleeds accumulated condensate automatically as pressure differential builds. The regulator here is the low-pressure type, so confirm its adjustment range against your working pressure with us before ordering. The square gauge is scaled in psi; MPa or bar scales and an external round gauge are alternatives in the series. Thread is G (BSPP) as coded; PT is the standard thread and NPT is an order option. Because flow is published as curves and not a single rating, 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 GR400-10 regulator with a GF400-10 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 rated flow number. Send us your application details and we will confirm the flow and datasheet figures for the GC400-10 on request.
The code L after the port size marks this as the low-pressure type regulator rather than the standard one. Its exact adjustment range is not published in the data we hold, so confirm your working pressure with us and we will verify suitability before you order.
