Airtac GC FRL Unit GC400C15ANWK
The AirTAC Airtac GC FRL Unit GC400C15ANWK is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station.

About the Airtac GC FRL Unit GC400C15ANWK
GC400C15ANWK is a GC-series three-piece F.R.L. combination from AirTAC: a separate air filter, pressure regulator and lubricator supplied as one set. The size 400 body is ported PT1/2, the filter bowl drains automatically, and the W code selects the 5 um element - a finer grade than the standard 40 um. The K code adds a reverse (check) valve, and the N code means no gauge is fitted. Regulator adjustment range is 0.15-0.9 MPa (20-130 psi) with the automatic drain, maximum working pressure is 1.0 MPa (145 psi), and the 400-size bowls are polycarbonate, rated for -5 to 70 C.
This is a genuine AirTAC part. The G-series F.R.L. comes in sizes 200, 300, 400 and 600 with a choice of ports, PT (standard), G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um (W) elements, gauge options and an optional check valve. Flow is published as curves rather than a single rating, so we confirm the datasheet and flow figures 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-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 GC400C15ANWK Is Used
Robotic weld cell clamp circuits
Supplies the clamp and positioner cylinders in a robotic welding cell; the check valve supports holding the clamp circuit if the upstream supply is interrupted.
Pneumatic press in a stamping shop
Conditions the air feeding a small pneumatic press, with the 5 um element guarding the press control valves and the automatic drain clearing condensate between cycles.
Machine tool coolant and chip valves
Feeds the actuated coolant and chip-discharge valves on a machine tool, where the check valve and fine element protect the pilot circuit on a 1/2-inch air drop.
Is the Airtac GC FRL Unit GC400C15ANWK the Right Station?
Size first: 200, 300, 400 and 600 step up in port and duty, and this listing is the size 400 body with PT1/2 ports in standard PT thread (G and NPT are catalogue variants). The W code gives the finer 5 um filtration grade instead of the standard 40 um, and the K code fits a reverse (check) valve - useful where you want the check function on the same set. The automatic drain suits unattended operation; a manual-drain version would widen regulator adjustment to 0.05-0.9 MPa (7-130 psi). Gauges and an optional mounting bracket are available in the series. 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 (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 GC400C15ANWK FAQ
AirTAC publishes G-series flow as curves rather than one rated figure, so no single number is quoted here. Share your line conditions with us and we will confirm the datasheet and flow curve for GC400C15ANWK on request before you order.
Only the trailing K: it adds a reverse (check) valve to the set. Everything else decodes the same - size 400, PT1/2 ports, PT thread, automatic drain, 5 um element, standard regulator type and no gauge.
