The AirTAC GC400-10 AirTAC F.R.L. Combination, 3/8 in PT 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The AirTAC GC400-10 is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one supply unit. This configuration is size 400 with a 3/8 in PT port, a manual drain on the filter bowl, a 40 um standard filter element, a low-pressure type regulator, a round gauge reading in psi, a reverse/check valve fitted and a mounting bracket included. In use it cleans water and particulate from the compressed air, holds the downstream pressure you set, and carries oil mist to the air tools and cylinders that need lubrication.
This is a genuine AirTAC part. The GC line is available in sizes 200, 300, 400 and 600 with a choice of port, thread (PT standard, G and NPT as order options), drain type, filter grade and gauge scale. Flow figures are published as curves rather than a single rating, 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. 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.

|---|---|
| 10 | Port size PT3/8". This body offers 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 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. |
| (blank) | PT 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: GF400-10 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.

Feeding a bench-mounted pneumatic press where the air supply needs water and swarf removed, a set working pressure, and oil mist carried to the cylinder seals.
Conditioning the air on a carton-sealing or wrapping line, where actuators run continuously and the manual drain suits a shift-start maintenance routine.
A single F.R.L. drop serving air tools and screwdrivers at an assembly cell, with the psi gauge letting operators check supply pressure at a glance.
Size 400 with a 3/8 in PT port suits lines that need more flow than the 200/300 sizes deliver; step up to 600 or down to 300 according to the pipe run and demand. The manual drain here means an operator opens the bowl drain periodically - choose automatic or differential-pressure drain codes if you want unattended purging. The 40 um element is the standard grade; specify the W code for 5 um where finer filtration is required. The round gauge is the external option, reading in psi; embedded square gauges with MPa, psi or bar scales are also available. PT is the standard thread, with G (BSPP) and NPT as order options. Note this is the low-pressure type regulator; its adjustment range is not published on the sheet we work from, so confirm it with us. Flow is published as curves, 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, not as a single rated figure, so we do not quote a number. Tell us your application and we will confirm the flow figures from the datasheet and check the sizing for you before you order.
The M in the code GC40010MLC2K specifies a manual drain on the filter bowl: condensate is released by opening the drain by hand. If you would rather not attend to it, the same size is available with automatic or differential-pressure drain - just specify the A code or leave the drain position blank when ordering.
