About the AirTAC GC400-10 FRL Unit (GC40010AC1WK)
The AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator that together clean, regulate and oil-mist lubricate a compressed-air supply. This GC40010AC1WK is built in size 400 with a 3/8 in. PT port as the standard thread, an automatic drain on the filter bowl, a round pressure gauge reading in MPa, and the finer 5 um filter element specified by the W code. The trailing K adds a reverse (check) valve, and the regulator adjusts over 0.15-0.9 MPa (20-130 psi) with this drain type.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600, with ports from 1/8 in. to 1 in., a choice of differential-pressure, automatic or manual drains, gauge styles and scales, and G (BSPP) or NPT threads as catalogue options. Maximum inlet pressure is 1.0 MPa (145 psi) and working temperature is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating; ask us and we will confirm the datasheet figures for 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 (GC40010AC1WK)
| GC400 | G-series F.R.L. combination, 400 body — sets the port range. |

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 (GC40010AC1WK) Is Used
Automated press cell air prep
Conditions air for pneumatic press and forming tools in a fabrication cell, combining the 5 um element, check valve, regulation and lubrication in one set.
Wire and cable machinery supply
Prepares air for the actuation circuits of a wire-drawing or cable-twisting line, where the lubricator services cylinders running through long production runs.
Concrete block plant pneumatics
Feeds filtered, regulated, lubricated air to the mould-closing cylinders and ejectors of a concrete blockmaking plant, with automatic drainage handling condensate.
Is the AirTAC GC400-10 FRL Unit (GC40010AC1WK) the Right Station?
This code combines the two most common upgrades: the W code fits the 5 um filter element instead of the standard 40 um, and the K code fits a reverse (check valve). Order GC40010AC1W without the K if your circuit already has check protection, or the plain GC40010AC1 for the standard element. Size 400 with a 3/8 in. PT port sits mid-range in the family, with sizes 300 and 600 covering smaller or larger porting. The automatic drain suits unattended duty, and manual or differential-pressure drains are orderable. The gauge reads in MPa, with psi (2) and bar (3) scales available, and G (BSPP) or NPT threads can be ordered. Flow appears as curves, not a single rated figure, so ask us to confirm sizing from the datasheet 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 (GC40010AC1WK) FAQ
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote one number here. Send us your operating pressure and required flow and we will confirm the sizing from the datasheet before you order.
W specifies the 5 um filter element instead of the standard 40 um element, and K fits a reverse (check) valve. The underlying size 400, 3/8 in. PT port, automatic drain and round MPa gauge are the same as the base GC40010AC1.
