About the Airtac GC FRL Unit GC400C10AF1WK
GC400C10AF1WK is a three-piece AirTAC G-series F.R.L. combination - separate filter, regulator and lubricator - with a reverse (check) valve fitted in the regulator section. It is built as the 400 size with PT 3/8 in ports, a 5 um filtering element (W), an automatic drain on the filter bowl, and a square embedded gauge reading in MPa. It cleans the compressed air, regulates downstream pressure across the 0.15-0.9 MPa (20-130 psi) adjustment range, meters oil mist to downstream equipment, and the check valve prevents reverse flow through the unit.
This is a genuine AirTAC part in the G-series range, offered in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, plus drain, filter-grade, gauge, thread and reverse-valve options. Maximum working pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C, non-freezing. Because AirTAC publishes flow as curves rather than a single rating, 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 GC400C10AF1WK Is Used
Fixture clamp circuits on machining fixtures
Supplying pneumatic swing clamps and toggle clamps on production fixtures, where the check valve helps hold the circuit against upstream fluctuations and the lubricator keeps clamp cylinders sealing smoothly.
Conveyor diverter and stopper stations
Conditioning air for diverters, stops and pushers along a sorting conveyor, with the automatic drain handling main-line condensate and the 5 um element protecting the solenoid valves driving the stations.
Woodworking nail and staple gun stations
Feeding pneumatic nailers and staplers at a workshop bench: filtered, regulated and lubricated air for the tools, with the embedded MPa gauge letting operators see set line pressure at a glance.
Is the Airtac GC FRL Unit GC400C10AF1WK the Right Station?
This 400-size set uses PT 3/8 in ports; choose the 200/300/600 size step according to the flow your circuit needs and specify G (BSPP) or NPT threads instead of PT if your piping requires them - all are catalogue options. The automatic drain suits installations that run unattended; manual (M) and differential-pressure (blank) drains are alternatives, and with a manual or differential-pressure drain the regulation range becomes 0.05-0.9 MPa (7-130 psi). The 5 um element is the fine-filtration choice against the standard 40 um. The K in this code adds the reverse/check valve; order without it if backflow is not a concern. Flow is published as curves, not a single rated value, so ask us to confirm sizing 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 GC400C10AF1WK FAQ
We do not state a single rated flow because AirTAC publishes G-series flow as curves, not one number. Send us your application details and we will confirm the flow curve and datasheet figures for this 400-size, 3/8 in combination on request.
K indicates that a reverse (check) valve is fitted, so flow cannot pass back through the unit; the same combination without K is the GC400C10AF1W. The rest of the decode is identical: 400 size, PT 3/8 in ports, automatic drain, 5 um filter element, square MPa gauge, standard regulator type.
