About the AirTAC GC400-15 FRL Unit (GC40015F1G)
GC40015F1G is an AirTAC G-series three-unit F.R.L. combination: separate filter, regulator and lubricator working as one set. The trailing G in the code means this size 400 unit has G1/2 parallel BSPP ports instead of the PT standard. It drains the filter bowl by differential pressure, keeps the standard 40 um filtration grade, and carries the square embedded gauge scaled in MPa. The set removes water and particulate, regulates downstream pressure and meters oil mist to cylinders, valves and air tools.
This is a genuine AirTAC part. The G-series F.R.L. range spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, drain options (differential-pressure, automatic or manual), 40 um standard or 5 um fine filtration, and PT, G(BSPP) or NPT thread choices. Maximum working (inlet) pressure is 1.0 MPa (145 psi); working temperature is -5 to 70 C, non-freezing. The size 400 bowls are polycarbonate (PC). Flow is published as curves rather than a single rated figure, so we confirm flow and datasheet 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: GF400-15 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 (GC40015F1G) Is Used
European-standard machine tool supply
Feeds regulated, lubricated air into machine tools plumbed with BSPP fittings, matching the G1/2 connections common on European-built equipment.
Process skid valve actuation
Supplies the actuated ball and butterfly valves on a process skid, where the regulator holds a steady set pressure for repeatable valve stroking.
Textile plant ring-frame air drops
Installed on ring-frame and winding-machine air drops so cylinders and thread-handling actuators receive filtered, oil-misted air at a stable pressure.
Is the AirTAC GC400-15 FRL Unit (GC40015F1G) the Right Station?
The G here is a thread choice, not a performance change: this set has G1/2 parallel BSPP ports for pipework and fittings built to that standard, while the PT version suits JP/IS-type installations and the T version gives NPT. Size 400 with 1/2 in ports is the upper-mid flow step of the G-series; we can compare the flow curve with your consumption before you commit. Drain is the differential-pressure type (automatic A and manual M are orderable), filtration is the standard 40 um grade with the 5 um (W) element optional, and the square gauge reads in MPa with other scales available. A mounting bracket can be added. Flow is published as curves, not 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 0.15 - 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 GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC GC400-15 FRL Unit (GC40015F1G) FAQ
There is no single rated flow to quote: AirTAC publishes G-series flow as curves. Share the air demand and working pressure of your circuit and we will confirm the flow and datasheet figures for this size 400, G1/2 BSPP set on request.
Only the thread. The trailing G means G1/2 parallel BSPP ports; the version without a thread letter has PT (the standard), and T would be NPT. Function, size, 40 um filtration, MPa square gauge and 0.15-0.9 MPa (20-130 psi) regulation range are otherwise identical.
