AirTAC GC400-10 FRL Unit (GC40010C1WK)
The AirTAC AirTAC GC400-10 FRL Unit (GC40010C1WK) 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 (GC40010C1WK)
The AirTAC GC series combines a separate air filter, pressure regulator and oil-mist lubricator into one three-piece F.R.L. set. The GC40010C1WK serves 3/8 in PT ports in size 400, uses the fine 5 um filter element (W) with the default differential-pressure drain, carries the external round gauge on an MPa scale, and is fitted with a reverse (check) valve (K) so downstream pressure is held if the upstream supply drops.
This is a genuine AirTAC part. The series spans sizes 200, 300, 400 and 600 with PT, G (BSPP) or NPT threads, 40 um or 5 um filtration, and MPa, psi or bar gauge scales. Maximum working pressure is 1.0 MPa (145 psi) with a -5 to 70 C, non-freezing temperature range. Flow is published as curves, not a single rating, so ask us to confirm sizing and 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 GC400-10 FRL Unit (GC40010C1WK)
| 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. |

| C | Gauge shape: Round. C is round, F is square. |

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 (GC40010C1WK) Is Used
Robotic Gripper Circuit
Condition the air feeding a six-axis robot's pneumatic gripper on a pick-and-place cell, where the check valve option helps hold the grip if the upstream supply dips mid-cycle.
Safety Clamp Hold-Up
Supply a workholding clamp circuit on a machining fixture, using the reverse valve so the clamped position is not lost during a momentary drop in shop air pressure.
Stamping Press Feed Line
Feed counterbalance and part-ejector cylinders on a mechanical stamping press with filtered, regulated, lubricated air, the 5 um element protecting the press's pilot valves.
Is the AirTAC GC400-10 FRL Unit (GC40010C1WK) the Right Station?
This code differs from the plain GC40010C1W only by the K option: a check valve that blocks reverse flow, useful where a brief supply interruption must not dump a clamped or gripped circuit. The 5 um element suits finer-protection duty; 40 um versions are available. The round gauge reads in MPa, and psi or bar scales plus square-gauge variants exist in the series.
PT is the standard thread for this code, with G (BSPP) and NPT offered as catalogue options. The filter bowl is polycarbonate at size 400 with differential-pressure drain. Since flow appears only as curves in the catalogue, share your duty cycle and we will confirm the size choice against 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 (GC40010C1WK) FAQ
We do not state a rated flow figure because AirTAC publishes G-series flow as curves, not a single number. Send us your application and we will confirm capacity from the datasheet on request before you commit to a size.
The K option fits a reverse (check) valve in the set, so air will not flow back toward the regulator if upstream pressure falls. It is specified where a gripper, clamp or other circuit must hold its pressure through brief supply dips; the same set without K is available as GC40010C1W.
