About the AirTAC GC400-15 FRL Unit (GC40015AF1K)
The GC40015AF1K is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one F.R.L. set. This configuration is the 400 size with 1/2 in PT ports. The filter element is the standard 40 um grade and the bowl is fitted with an automatic drain, so collected water is expelled without manual attention. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi) and carries the embedded square gauge with an MPa scale. A reverse/check valve is fitted, and a mounting bracket is included.
This is a genuine AirTAC part. The GC combination is available in sizes 200, 300, 400 and 600 with matching port sizes, and options include manual or differential-pressure drains, a 5 um filter element (code W), gauge scale choices of MPa, psi or bar, G (BSPP) or NPT thread variants, and external round gauges. Flow figures are published as curves rather than a single rating, 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 0.15 - 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 (GC40015AF1K) Is Used
Automotive paint-shop air supply
Feeding spray guns and air-assisted applicators on a paint line, where the filter removes water and particulate, the regulator holds a steady set pressure and the lubricator mists oil to the air motor circuit.
Bottling-line conveyor cylinders
Supplying the pneumatic stopper, pusher and lift cylinders along a bottling or packaging conveyor, with the check valve holding the downstream circuit and the automatic drain clearing condensate through long shifts.
CNC machine-tool clamping circuits
Powering pneumatic clamps and tool-change actuators on a machining centre, where a stable regulated pressure and lubricated air protect the clamping sequence across the working day.
Is the AirTAC GC400-15 FRL Unit (GC40015AF1K) the Right Station?
Choose the GC size by the port and flow step your line needs: 200, 300, 400 and 600 step up in port size and flow capacity, with this 400 unit at 1/2 in PT. Drain type is a real choice: automatic (this unit) suits unattended duty, manual drain suits supervised points, and differential-pressure drain is the default. Filter grade is 40 um standard or 5 um with code W where finer particulate removal is wanted. Gauge scale can be MPa, psi or bar, and the embedded square gauge is standard with an external round gauge optional. Thread is PT as standard; G (BSPP) and NPT are order options. A bracket is included, and the reverse/check valve (code K) is fitted on this unit.
Flow for this family is published as curves, not a single rated figure, so please ask us to confirm sizing against your air consumption 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 (GC40015AF1K) FAQ
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote one number. Tell us your application and air consumption and we will confirm the flow and sizing from the datasheet on request.
The A in GC40015AF1K means the filter bowl has an automatic drain, which expels collected water without anyone opening it - useful on lines that run unattended. Manual and differential-pressure drains are also available in the GC range if your maintenance routine prefers them.
