About the AirTAC GC400-15 FRL Unit (GC40015MF1)
The AirTAC GC series is a three-piece F.R.L. combination: separate filter, regulator and lubricator units assembled into one air-preparation set. This GC40015MF1 is the 400 size with 1/2 in PT ports, a manual drain on the filter bowl, the standard 40 um filter element and an embedded square pressure gauge reading in MPa. In use it dries and cleans the air, locks in your set pressure and meters oil mist to everything downstream.
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 comes in 200, 300, 400 and 600 sizes with drain, filter-grade, gauge and thread options. Rated flow is published as curves, not a single number, 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 (GC40015MF1)
| 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. |
| (blank) | No reverse-flow valve (the default). |
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 (GC40015MF1) Is Used
Assembly line stations
Conditions the air at the drop point of an automotive assembly station, feeding clamp cylinders and air tools from one filtered, regulated and lubricated supply.
Pneumatic valve actuation
Prepares the air supply for quarter-turn pneumatic actuators on a process skid, where stable regulated pressure and clean air keep valve cycling consistent.
Cabinet shop nailers and sanders
Feeds pneumatic nailers, staplers and finish sanders in a woodworking shop, with the lubricator oil-misting the tools and the manual drain cleared during shift checks.
Is the AirTAC GC400-15 FRL Unit (GC40015MF1) the Right Station?
The 400 size with 1/2 in PT ports is the natural pick when one set feeds a whole station or machine; check the flow curve against your consumption before stepping to 600 or 300. Manual drain is right for installations that are visited regularly; choose A (automatic) or blank (differential-pressure) drain where the bowl cannot be reached. The element here is the standard 40 um; add W for 5 um. This version carries the embedded square gauge with an MPa scale - psi and bar scales are orderable, as are G (BSPP) and NPT threads instead of the standard PT.
Flow is published as curves rather than a single rating, 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 0.05 - 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 (GC40015MF1) FAQ
AirTAC publishes GC-series flow as performance curves rather than one rated figure, so we do not state a single number. Share your operating pressure and air consumption and we will confirm the correct size from the datasheet on request before you order.
The blank gauge position with F gives the embedded square gauge, and the trailing 1 sets its scale to MPa - the unit you are reading on the regulator. Scale 2 (psi) and scale 3 (bar) versions are catalogue options, and an external round gauge is also available, so match the scale to the gauges already used on your machine.
