About the AirTAC GC400-15 FRL Unit (GC40015MC3)
The AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled as one air-preparation set. This GC40015MC3 is the 400 size with 1/2 in PT ports, a manual drain on the filter bowl, the standard 40 um filter element and a round pressure gauge reading in bar. It removes water and particulate from compressed air, holds your set downstream pressure and adds oil mist for tools and cylinders.
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 and thread options. Rated flow is published as curves rather than 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 (GC40015MC3)
| 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). |
| C | Gauge shape: Round. C is round, F is square. |
| 3 | Gauge scale: bar. 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 (GC40015MC3) Is Used
CNC machining cells
Prepares the air feeding pneumatic vise and clamping cylinders and chip-blowing nozzles on a CNC machining centre, with the manual drain cleared at the start of each shift.
Packaging line actuators
Filters, regulates and lubricates the air supplying the fold, seal and gripper cylinders on a carton-forming and sealing line.
Automotive service air tools
Supplies regulated, oil-misted air to impact wrenches, ratchets and air chisels at a vehicle service bench, keeping tool motors lubricated in daily use.
Is the AirTAC GC400-15 FRL Unit (GC40015MC3) the Right Station?
The 400 size with 1/2 in PT ports is the usual step where one set feeds several downstream valves and actuators; move to 600 or down to 300 only if the flow curve for your consumption says so. Manual drain means an operator drains the filter bowl periodically - choose the A (automatic) or blank (differential-pressure) variants if the unit sits where nobody can reach it. The standard element is 40 um; the W suffix gives 5 um filtration. Thread is PT as standard, with G (BSPP) and NPT available as catalogue options; the gauge here reads in bar, and MPa or psi scales can be ordered.
Flow for the GC series is published as performance curves, not a single rating, so send us your operating pressure and air consumption and we will confirm sizing from the datasheet before you order.
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 (GC40015MC3) FAQ
AirTAC publishes flow for the GC series as performance curves rather than a single rated figure, so we do not quote one number here. Tell us your operating pressure and air consumption and we will confirm sizing from the datasheet on request before you order.
The M in the code is the manual drain: an operator opens the filter bowl drain periodically to remove collected water. If the unit is mounted where nobody can reach it, order the same set with A (automatic drain) or the blank differential-pressure drain instead - the regulation range then becomes 0.15-0.9 MPa (20-130 psi) versus 0.05-0.9 MPa (7-130 psi) for this manual-drain version.
