AirTAC GC400-15 FRL Unit (GC40015ANK)
The AirTAC AirTAC GC400-15 FRL Unit (GC40015ANK) 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.

About the AirTAC GC400-15 FRL Unit (GC40015ANK)
GC40015ANK is a genuine AirTAC G-series three-unit F.R.L. set: a separate air filter, pressure regulator and lubricator that together condition compressed air at one station. This 400-size set is ported PT1/2, the filter bowl has an automatic drain, the element is the standard 40 um grade, and the K code fits a reverse (check) valve; no gauge is fitted as coded (N). The standard-type regulator covers a 0.15-0.9 MPa (20-130 psi) setting range with the automatic drain, inlet pressure is up to 1.0 MPa (145 psi), the medium is compressed air, and the units operate from -5 to 70 C (non-freezing). Bowls on the 400 size are polycarbonate.
This is a genuine AirTAC part. The GC combination comes in 200, 300, 400 and 600 sizes, with a choice of drain types, 40 um or 5 um elements, gauge options, the reverse valve, and PT, G (BSPP) or NPT threads. AirTAC publishes flow as characteristic curves rather than a single rating, so we confirm flow and datasheet figures on request before you order.

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 (GC40015ANK)
| 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". |
| A | Drain: Automatic 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. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 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: GF400-15 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 (GC40015ANK) Is Used
Robotic welding cell
A welding robot's pneumatic gripper and torch-clean circuits run on conditioned air from this set, with the reverse valve helping hold the regulated circuit between weld sequences.
Torque-controlled bolting station
A multi-spindle bolting fixture keeps its regulated supply through this set, the check valve guarding the downstream setting when the main supply is interrupted.
Machine control cabinet air supply
Control cabinets driving pneumatic pilot valves take filtered, regulated, lubricated air from this PT1/2 set, with automatic drainage so no one has to open the cabinet to drain the bowl.
Is the AirTAC GC400-15 FRL Unit (GC40015ANK) the Right Station?
Step between the 200/300/400/600 G-series sizes to match port size and flow demand; the 400 size with its 1/2 inch port sits mid-range for general plant air. Drain choice is automatic (fitted here), manual or the differential-pressure default, so pick automatic where bowls are hard to reach or the line runs unattended. Filter grade is 40 um standard or the 5 um W option; the K code adds a reverse (check) valve where downstream pressure must be held, and a gauge can be added where it is omitted here. PT is the standard thread with G (BSPP) and NPT as catalogue options.
AirTAC publishes flow as curves, not a single rated figure, so ask us to confirm sizing against your application before ordering.
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 (GC40015ANK) FAQ
AirTAC publishes flow as characteristic curves rather than a single rated number, so we do not quote a one-line figure. Tell us your application and we will confirm the relevant flow and datasheet figures on request before you order.
K means a reverse (check) valve is fitted on the regulator section of this set, which holds downstream pressure when the upstream supply drops. The standard GC40015AN without K is the same set with no check valve.
