About the AirTAC GC400-15 FRL Unit (GC40015F1WK)
The GC series is AirTAC's three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator supplied as one set. This GC40015F1WK is the size 400 unit with PT1/2 ports, the 5 um filtration grade (W), a differential-pressure drain, an embedded square MPa gauge and the K suffix, which means the reverse (check) valve option is fitted. Filter, regulation and lubrication therefore arrive in one order, with the regulator adjustable from 0.15 to 0.9 MPa (20-130 psi) with this drain type.
This is a genuine AirTAC part. Maximum working pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the size 400 bowls are polycarbonate. The GC family is available in sizes 200, 300, 400 and 600, with G (BSPP) or NPT threads, automatic or manual drains, 40 um standard elements, other gauge scales and the check valve as orderable options. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures on request.

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 GC400-15 FRL Unit (GC40015F1WK)
| GC400 | G-series F.R.L. combination, 400 body — sets the port range. |
|---|---|
| 15 | Port size PT1/2". 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: GF400-15 filter, GR400-15 regulator and GL400-15 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 GC400-15 FRL Unit (GC40015F1WK) Is Used
Solenoid-valve manifold supply on an automation skid
Prepares the air ahead of a solenoid-valve manifold on a machine skid: the 5 um element and regulator protect and feed the valves, and the K suffix covers circuits whose design calls for the reverse (check) valve option.
Maintenance-shop air-rail and impact wrench station
Conditions the drop feeding impact wrenches and ratchets at a plant maintenance station, with the lubricator misting the tools and the MPa gauge matching the shop's other AirTAC sets.
Pneumatic clamp fixture feed on an assembly line
Serves the swing clamps and risers of a welded fixture on an assembly line, combining 5 um filtration, stable regulated pressure and oil mist in a single size 400 set.
Is the AirTAC GC400-15 FRL Unit (GC40015F1WK) the Right Station?
Choose this code when your specification calls for the K option: it is the standard GC40015F1W - size 400, PT1/2 ports, 5 um filtration, differential-pressure drain and square MPa gauge - with the reverse (check) valve fitted. If your circuit does not call for the valve, order the same code without the K. Drain upgrades to automatic (A) or manual (M) exist, and psi (2) or bar (3) gauge scales can be selected. Thread: PT is standard, with G (BSPP) and NPT as catalogue options. Flow is published as curves, not one rated number, so ask us to confirm sizing against your application before you order.
Quick checklist
- ✓ Body size for your peak flow (PT1/2" 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 GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC GC400-15 FRL Unit (GC40015F1WK) FAQ
Flow for the GC series is published by AirTAC as curves, not as a single rated figure, so we do not state one number here. Tell us your flow and pressure requirement and we will confirm the correct datasheet figures on request before you order.
K is the AirTAC code for the reverse (check) valve option being fitted to the unit. The same set without the valve is ordered as GC40015F1W; all other settings - size 400, PT1/2, 5 um filtration, differential-pressure drain and MPa square gauge - are identical.
