About the Airtac GC FRL Unit GC400C15AC1WK
The AirTAC GC series is a three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled for one compressed-air line. This size 400 configuration carries a PT1/2 (1/2 in) port, a 5 um (W) filter element instead of the standard 40 um grade, an automatic drain on the filter bowl, a round external pressure gauge scaled in MPa, and a fitted check (reverse) valve that helps hold the downstream setting when the upstream supply dips. Maximum working pressure is 1.0 MPa (145 psi), the filter and lubricator bowls are polycarbonate at 400 size, and the temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600, with differential-pressure, automatic or manual drain, 40 um or 5 um filtration, embedded square or external round gauges in MPa, psi or bar scales, the check valve as an option (order without K for a plain set), and G (BSPP) or NPT threads as catalogue alternatives to the PT standard. Flow is published as curves rather than a single rating, so we confirm datasheet 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 GC400C15AC1WK Is Used
Automotive assembly cell
Supplying regulated, filtered and lubricated air to impact wrenches and clamp cylinders at an automotive assembly cell, with the check valve helping hold the set pressure during supply fluctuations.
Distribution centre sorters
Conditioning the air feeding the transfer and divert cylinders of a parcel sorting conveyor, where the automatic drain keeps the bowl clear across multi-shift operation.
Welding fixture clamping
Providing clean, oil-misted and pressure-controlled air to the swing clamps and cylinder packages on a robotic welding fixture, with the 5 um element guarding the fixture valves.
Is the Airtac GC FRL Unit GC400C15AC1WK the Right Station?
Size 400 with the PT1/2 port suits lines whose consumption has outgrown a GC300 (3/8 in) set, while GC600 covers 3/4 in headers. The automatic drain here removes condensate without operator attention; choose manual drain where an operator drains the bowl routinely, or differential-pressure drain for the standard configuration. The 5 um (W) element is the pick ahead of sensitive valves and cylinders; 40 um remains the standard general-air grade. This set carries the round external gauge in MPa; the embedded square gauge and psi or bar scales are also available. The trailing K adds the check valve - drop it from the code if you do not need that function. PT is the standard thread; order G (BSPP) or NPT as catalogue alternatives.
Flow is published as curves, not a single rated figure, so share your pressure and consumption requirements and we will confirm the correct size from the datasheet 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 GC400C15AC1WK FAQ
AirTAC publishes GC-series flow as curves rather than a single rated figure, so we do not quote one number on the page. Send us your operating pressure and air consumption and we will confirm the flow data from the datasheet on request.
K specifies that a reverse (check) valve is fitted in the set, helping hold downstream pressure when the upstream supply fluctuates. Order the same code without the K if your circuit does not need that function.
