About the AirTAC GC400-10 FRL Unit (GC40010F1K)
GC40010F1K is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one supply set for a 3/8in PT port. The filter stage removes water and particulate with the standard 40um element, the regulator holds your set downstream pressure across 0.15-0.9 MPa (20-130 psi) with this differential-pressure drain configuration, and the lubricator meters oil mist into the air. A reverse (check) valve is fitted, and the embedded square pressure gauge reads in MPa.
This is a genuine AirTAC part in size 400, the larger step of the GC range (200/300/400/600). Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C non-freezing, and the filter and lubricator bowls are polycarbonate at this size. AirTAC publishes flow as curves rather than a single rated figure, so ask us for the datasheet and we will confirm sizing against 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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.
Model Code: AirTAC GC400-10 FRL Unit (GC40010F1K)
| 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)). |
| (blank) | Standard 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. |
| 1 | Gauge scale: MPa. 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.
Size Class & How It Differs From GFC
- GC200PT1/8" - PT1/4"
- GC300PT1/4" - PT1/2"
- GC400PT3/8" - PT1/2"
- GC600PT3/4" - PT1"
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.

Where the AirTAC GC400-10 FRL Unit (GC40010F1K) Is Used
CNC machining centre air supply
Feeds the tool changer, clamps and chip-blow nozzles on a machining centre, with the lubricator oiling actuator seals and the check valve fitted in the circuit.
Packaging line case sealer
Regulates and lubricates the clamp, fold and tape-head cylinders on a carton sealing line fed from a shared 3/8in drop.
Pneumatic assembly cell
Supplies impact drivers, ratchets and air cylinders at assembly stations that need filtered, regulated, oil-misted air.
Is the AirTAC GC400-10 FRL Unit (GC40010F1K) the Right Station?
Size 400 with a 3/8in PT port suits circuits where a 1/4in set would restrict supply; step down to 300 or up to 600 as your air demand changes. This code carries the differential-pressure drain (the default), the 40um standard element and the embedded square MPa gauge; order W for a 5um element, A or M for automatic or manual drain, and the C or F gauge codes with a 2 or 3 scale for psi or bar. The K in this code means the reverse (check) valve is fitted. Thread is PT as standard, with G (BSPP) and NPT available as catalogue options, and bracket mounting can be added. Because AirTAC publishes flow only as curves, ask us to confirm this model against your air demand before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" here)
- ✓ Element 40 µm or 5 µm
- ✓ Drain sets the regulating band
- ✓ Gauge fitted, shape and scale
- ✓ Three-unit (GC) or two-unit (GFC) layout
- ✓ Oil mist acceptable downstream
Installation & Maintenance Notes
- check Install with the airflow arrow: filter first, lubricator last.
- check Mount vertically, bowls down.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Adjust only within 0.15 - 0.9 MPa (20 - 130 psi).
- check Drain condensate before the bowl fills; check the oil level.
- check Keep the station above freezing (-5 to +70 °C, unfreeze).
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 GC400-10 FRL Unit (GC40010F1K) FAQ
AirTAC does not publish a single rated flow number for this unit; flow is given as performance curves that depend on upstream pressure and the set pressure. Send us your supply conditions and required demand, and we will read the datasheet curve and confirm sizing on request.
The GC set filters, regulates and lubricates in three bodies, so the lubricator can be topped up or serviced without disturbing the filter-regulator. If your circuit needs no oil mist at all, a GFR filter-regulator covers filtration and regulation in one body instead.
