About the Airtac GC FRL Unit GC400C15N
The GC400C15N is a genuine AirTAC three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, matched as a set for 1/2 inch PT ports. This configuration carries the standard 40 um filter element with the default differential-pressure drain on the filter bowl, and the N code means no pressure gauge is fitted. In use it cleans water and particulate out of the compressed air, holds a steady downstream pressure adjustable from 0.15-0.9 MPa (20-130 psi), and meters oil mist into the air line to lubricate downstream tooling.
This is a genuine AirTAC part in the G series size 400 range, which spans sizes 200, 300, 400 and 600 with a choice of ports, threads, drains, filter grades and gauge options. Maximum working pressure is 1.0 MPa (145 psi) and the service temperature range is -5 to 70 C (non-freezing); the bowls on this size are PC (polycarbonate). Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet flow and sizing 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.

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-C1 filter, GR400-C1 regulator and GL400-C1 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 GC FRL Unit GC400C15N Is Used
CNC machining centre air supply
Installed on the compressed air drop feeding a CNC machining centre, the set dries and filters the supply, holds a stable pressure to the machine's pneumatic circuits and lubricates the air going to tool-change and clamping cylinders.
Packaging line actuation
Mounted at the inlet of a packaging machine's air preparation panel, it conditions the supply before distribution to sealing jaws, diverters and pusher cylinders, protecting valves from water and debris while keeping moving parts oiled.
Plant air ring main take-offs
Fitted at take-off points on a factory ring main, the combination gives each production cell its own filtered, regulated and lubricated air supply independent of what neighbouring cells draw from the same header.
Is the Airtac GC FRL Unit GC400C15N the Right Station?
Start with size and port: the 400 series with its 1/2 inch PT port suits mid-to-large air lines, and stepping up to 600 or down to 300 changes the port and the flow capacity, so match the step to the air demand of the circuit. Drain choice on the filter is differential-pressure here (the default); automatic (A) and manual (M) drains are orderable options. The standard element is 40 um, with a finer 5 um (W) element available if the application calls for it. Thread is PT as standard, with G (BSPP) and NPT available as catalogue options. This N-coded unit comes without a gauge; gauge and scale variants can be ordered instead if a local pressure readout is wanted. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (See datasheet 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-C1 regulator with a GF400-C1 filter on that branch.
Airtac GC FRL Unit GC400C15N FAQ
AirTAC publishes flow for the GC series as performance curves rather than a single rated figure, so we do not quote a rated flow number. Tell us your application and line conditions and we will confirm the datasheet flow figures and check the sizing for you on request.
Yes. The N in GC400C15N means no pressure gauge is fitted as standard; gauge and scale variants of the same GC400 set can be ordered instead if you want a local readout of the regulated pressure.
