The AirTAC GC400-10 AirTAC F.R.L. Combination, PT3/8, 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 40 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC400-10 is a three-piece AirTAC F.R.L. combination: a separate filter, pressure regulator and oil-mist lubricator assembled as one air-preparation set. This size 400 unit carries a PT 3/8 inch port, a 40 um filter element with a manual drain bowl, and the low-pressure regulator type, so it suits circuits that run below standard line pressure. The square pressure gauge fitted here reads in psi, a reverse/check valve is included, and the set ships with its mounting bracket.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options include automatic or differential-pressure drains, a 5 um filter element, alternative gauge scales and G or NPT threads. Rated flow is published as curves rather than a single figure, so ask us to confirm the datasheet numbers 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.

|---|---|
| 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). |
| F | Gauge shape: Square. 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. |

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.

Installed at the 3/8 inch take-off feeding a production cell, the set cleans the shop air, holds the circuit at the low working pressure the tooling calls for, and carries oil mist downstream to keep air cylinders and valves running smoothly.
Mounted on the bracket beside a conveyor section, the unit supplies filtered, regulated and lubricated air to the stopper cylinders and gate actuators that index cartons along the line, with the psi gauge giving operators a visible setpoint.
Fitted ahead of clamps, presses and air motors on a machine bench, the combination removes water and particulate at the 40 um grade, regulates the supply at low pressure, and mists oil into the air so the tooling's moving parts stay lubricated.
Start with the port step: this unit is size 400 with a 3/8 inch PT port, one step up from the 300/1/4 inch class, so pick it when your line plumbing is 3/8 inch and your air demand sits above what a smaller set serves. The manual drain here means someone opens the bowl drain during checks; choose the automatic or differential-pressure drain variant if the unit sits where regular draining is impractical. The 40 um element is the standard grade for general plant air; specify the W code for the 5 um element where finer particulate removal matters. The fitted square gauge reads in psi; MPa and bar scales and an external round gauge are order options. Thread is PT as standard, with G (BSPP) and NPT available to order, and the bracket is included. Because rated flow is published only as curves, not a single number, send us your application details and we will confirm sizing against the datasheet 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 GR400-10 regulator with a GF400-10 filter on that branch.
AirTAC publishes flow for this series as curves rather than a single rated figure, so we do not quote one number. Send us your application details and we will confirm the flow and datasheet figures for the GC400-10 on request before you order.
The M in the model code sets a manual drain: the bowl is emptied by hand during routine checks. If the unit will be mounted where regular draining is awkward, order the automatic (A) or differential-pressure (blank) drain variant of the same GC400 set instead.
