AirTAC GC400-10 FRL Unit (GC40010C1K)
The AirTAC AirTAC GC400-10 FRL Unit (GC40010C1K) 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 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GC400-10 FRL Unit (GC40010C1K)
The AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, so incoming compressed air is cleaned, regulated and lubricated in one installation. This GC40010C1K is the 400 size with 3/8" PT ports, the standard differential-pressure drain on the polycarbonate filter bowl, the standard 40 um filter element, a round external gauge with MPa scale, and a reverse (check) valve fitted - the K suffix marks that valve.
This is a genuine AirTAC part. The G-series covers 200, 300, 400 and 600 sizes with a choice of thread (PT as standard, G and NPT to order), drain types, filter grades, gauges and valve options, with a maximum working pressure of 1.0 MPa (145 psi). Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and the full datasheet against your application before ordering.

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 (GC40010C1K)
| 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). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 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: GF400-10 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 (GC40010C1K) Is Used
Assembly bench tool circuits
Runs pneumatic screwdrivers and riveters at workstations, with the MPa gauge giving operators a visible, stable set pressure.
Calibration and test benches
Prepares regulated air for instrument test rigs, where the 40 um element and visible gauge support repeatable bench conditions.
Machine tool coolant and chip systems
Supplies air to chip augers, coolant nozzles and curtain blasts on machine tools, with clean, lubricated, regulated air throughout.
Is the AirTAC GC400-10 FRL Unit (GC40010C1K) the Right Station?
This is the same 400-size, 3/8" PT three-unit set as the GC40010C1 - differential-pressure drain, 40 um element, round MPa gauge - with the K option adding a reverse (check) valve. Choose it when your circuit calls for that valve to be part of the air preparation unit. The regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) with the differential-pressure drain; max working pressure is 1.0 MPa (145 psi) and operating temperature is -5 to 70 C, non-freezing. Drain type, filter grade, gauge scale and G/NPT thread are all orderable alternatives. Flow is published as curves, not a single rating, so confirm sizing with us 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 (GC40010C1K) FAQ
Flow for the GC series is published by AirTAC as curves rather than one rated figure, so we do not state a number on the page. Send us your application details and we will confirm the curve data and correct sizing from the datasheet on request.
Only the K option: a reverse (check) valve is fitted to this unit. Both are 400-size, 3/8" PT three-piece F.R.L. sets with a differential-pressure drain, 40 um filter element and a round external MPa gauge. Order the GC40010C1 if you do not need the valve.
