About the AirTAC GC400-15 FRL Unit (GC40015MF1K)
The AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator piped as one air-preparation set. This GC40015MF1K is the 400 size with 1/2 in PT ports, a manual drain, the standard 40 um filter element, an embedded square gauge reading in MPa and a fitted reverse (check) valve (K). Use it where a standard set would work but backflow through the set needs blocking.
This is a genuine AirTAC part rated to 1.0 MPa (145 psi) inlet, with a manual-drain regulation range of 0.05-0.9 MPa (7-130 psi) and a working temperature of -5 to 70 C, non-freezing. The G series spans 200, 300, 400 and 600 sizes with drain, filter-grade, gauge, thread and reverse-valve options. Flow is published as curves, not a single figure, so ask us to confirm the datasheet and sizing for your application 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 0.05 - 0.9 MPa (7 - 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 (GC40015MF1K)
| 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". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 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. |
| (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 (GC40015MF1K) Is Used
Automotive assembly clamps
Conditions the air feeding power-clamp cylinders on an assembly line, with the reverse valve in the circuit where the downstream side must not backfeed the supply.
Service van air tools
Prepares the shop-air drop that fills a mobile service van setup, delivering regulated, oil-misted air to impact wrenches and air ratchets used on the road.
Printing press cylinders
Filters, regulates and lubricates the air for impression and delivery cylinders on a printing press, where consistent set pressure keeps registration steady.
Is the AirTAC GC400-15 FRL Unit (GC40015MF1K) the Right Station?
This code is the MF1 set plus the K suffix, which fits a reverse (check) valve; order GC40015MF1 without the K if you do not need it. The 400 size with 1/2 in PT ports typically feeds a machine or station from one drop - validate against the flow curve before ordering. Manual drain suits attended installations; the A (automatic) and blank (differential-pressure) drain versions suit unattended ones. The 40 um element is standard, with 5 um (W) available; the square gauge reads in MPa, and psi or bar scales plus G (BSPP) and NPT threads are orderable.
Because flow is published as curves rather than a single rating, send us your duty point and we will confirm sizing from the datasheet on request.
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 0.05 - 0.9 MPa (7 - 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 (GC40015MF1K) FAQ
Yes. AirTAC publishes flow for the GC series as performance curves, not a single rated figure, so we do not quote a number here. Send us your operating pressure, downstream consumption and this code, and we will confirm the sizing from the datasheet on request.
K is the reverse-valve option: a reverse (check) valve is fitted to this set, so the same GC40015 series code without K - for example GC40015MF1 - is the version without it. Choose the K version when the application needs backflow blocked through the set; we can confirm the datasheet details on request.
