AirTAC GC400-10 FRL Unit (GC40010F1WK)
The AirTAC AirTAC GC400-10 FRL Unit (GC40010F1WK) 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).

About the AirTAC GC400-10 FRL Unit (GC40010F1WK)
GC40010F1WK is an AirTAC GC-series three-unit F.R.L. combination for a 3/8in PT port, combining the fine 5um W filter element, a regulator and an oil-mist lubricator in one set. The regulator holds your set downstream pressure across 0.15-0.9 MPa (20-130 psi) with this differential-pressure drain configuration, the embedded square gauge reads in MPa, and the K in the code means a reverse (check) valve is fitted in the circuit.
This is a genuine AirTAC part in size 400 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 for your circuit.

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 (GC40010F1WK)
| 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. |
| W | Filtering grade 5 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.
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 (GC40010F1WK) Is Used
Bottling line valve actuation
Supplies the actuated fill and diverter valves on a bottling line, with the 5um element protecting the valve internals and a check valve fitted in the circuit.
MRO workshop service drops
Conditions the 3/8in service drops in a maintenance workshop where air tools, cylinders and blow guns share one filtered, regulated, lubricated supply.
Case erecting and palletising cell
Feeds grippers, clamps and pushers in a case-erecting and palletising cell that runs on clean, oiled, pressure-regulated air.
Is the AirTAC GC400-10 FRL Unit (GC40010F1WK) the Right Station?
This code brings together three choices: the 5um W filter grade for particulate-sensitive circuits, the K option with the reverse (check) valve fitted, and the embedded square MPa gauge. Size 400 with a 3/8in PT port sits above the 300 series; step to 600 for larger demand. The drain is the differential-pressure default - select A for automatic or M for manual if your duty suits it better - and gauge scales 2 (psi) or 3 (bar) are orderable variants. Thread is PT as standard, with G (BSPP) and NPT available as catalogue options. 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 (GC40010F1WK) FAQ
AirTAC states flow for this series as performance curves, not as a single rated number, so we will not quote a figure we cannot stand behind. Share your supply pressure and demand and we will confirm the sizing from the datasheet on request.
K specifies that a reverse (check) valve is fitted with the set. The same unit without the K is the GC40010F1W. Everything else decodes identically: size 400, 3/8in PT port, 5um element, differential-pressure drain, square MPa gauge and standard regulator.
