About the Airtac GC FRL Unit GC400C10NWK
GC400C10NWK is a genuine AirTAC G-series three-unit F.R.L. combination: separate air filter, pressure regulator and lubricator assembled as one set, with the trailing K adding a reverse (check) valve that blocks backflow through the unit. The 400 size carries PT 3/8 in ports. This configuration is the 5 um (W) filter grade, the differential-pressure drain (the standard drain responding to water buildup in the bowl) and no gauge (N code). Maximum working pressure is 1.0 MPa (145 psi); working temperature is -5 to 70 C, non-freezing. The 400-size bowls are polycarbonate (PC).
This is a genuine AirTAC part. The G-series F.R.L. line spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, 40 um standard or 5 um (W) filtration, automatic, manual and differential-pressure drain variants, gauge options and a K check-valve variant on regulator-equipped sets. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application.

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 GC400C10NWK Is Used
Power clamping on a machining line
Conditions and holds air to hydraulic/pneumatic clamp fixtures on a transfer line, where the check valve helps keep the clamped side from dumping back through the set during a supply dip.
Wire and cable processing machines
Feeds the pneumatic cutters, strippers and tensioner cylinders of a wire processing machine, with the 5 um grade protecting the small cycling valves and the check valve on the inlet side.
Electronics assembly actuator banks
Supplies banks of small pick-and-place and press-fit actuators on an electronics assembly line, combining filtration, regulation, lubrication and backflow protection in one mounted set.
Is the Airtac GC FRL Unit GC400C10NWK the Right Station?
Choose this code over the plain GC400C10NW when you want the K check valve fitted, holding the downstream side against backflow through the set. Size 400 with PT 3/8 in ports suits lines plumbed at that size; step to 200/300/600 as flow needs change. The W code selects the 5 um filter grade for air feeding sensitive valves and cylinders; 40 um is the standard grade. Drain is the differential-pressure type (default); automatic (A) and manual (M) are separate codes. No gauge is fitted (N code); round and square gauges with MPa, psi or bar scales can be ordered. Thread is PT as the standard; G (BSPP) and NPT are catalogue options to order. Flow is published as curves, not a single rating, 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 GC400C10NWK FAQ
There is no single rated flow figure to quote: AirTAC publishes flow for these units as curves. Share your working pressure and air demand and we will check the datasheet curves and confirm the fit on request before you order.
The trailing K means a reverse (check) valve is fitted, so air flows one way through the set and the downstream side is blocked from pushing back through the unit. The same unit without the K is coded GC400C10NW.
