About the Airtac GC FRL Unit GC400C15MC1WK
The AirTAC GC400C15MC1WK is a three-piece F.R.L. combination: separate air filter, pressure regulator and lubricator in line. This 400-size unit takes PT1/2 ports, drains its filter bowl manually, filters to the finer 5 um grade (the W option), and carries a round external gauge in MPa. The trailing K means a reverse/check valve is fitted, so downstream pressure is held if the upstream supply fails.
This is a genuine AirTAC part from the G series, available in 200, 300, 400 and 600 sizes with drain, filter-grade, gauge, reverse-valve and thread options (PT standard, G and NPT to order). Flow is published as curves rather than a single rating, so we confirm the datasheet 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 GC400C15MC1WK Is Used
Actuated valve manifold on a water-treatment skid
Installed upstream of the solenoid valves driving actuated butterfly valves on a treatment skid, this set supplies clean, regulated, lubricated air, while the check valve keeps the actuators pressurised if the plant air supply drops out.
Safety clamp circuit on a press line
Feeding the hold-clamp circuit of a stamping press, the unit filters to 5 um and regulates pressure to the clamps; the reverse valve helps maintain clamp holding pressure during a momentary supply interruption.
Mobile maintenance rig for plant repairs
Built into a wheeled maintenance rig that plugs into different shop air points, this F.R.L. set conditions whatever supply it is connected to, with the check valve preventing backflow between the rig and the drop it is hooked to.
Is the Airtac GC FRL Unit GC400C15MC1WK the Right Station?
GC400C15MC1WK is the 400-size, PT1/2 F.R.L. set for circuits where holding downstream pressure matters, thanks to the fitted check valve. Compared with GC400C15MC1W it adds only the K option; drop it if your circuit does not need back-holding. Step to the 300 size on 3/8" for lighter demand or the 600 size for heavier lines. Manual drain suits supervised plant; automatic and differential-drain variants cover unattended points.
Gauge is the round external type on an MPa scale; embedded square gauges and psi/bar scales are alternatives. Thread is PT as standard with G (BSPP) and NPT orderable. Flow is published only 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 GC400C15MC1WK FAQ
None that we can state here: AirTAC publishes G-series flow as characteristic curves, not a single rated number. Tell us your supply pressure and air demand and we will confirm the sizing and the full datasheet for this 400-size, PT1/2 set on request.
K means a reverse/check valve is fitted, so air will not flow back toward the unit when upstream pressure is lost. The same combination without K is GC400C15MC1W; both share the 400 size, PT1/2 ports, manual drain, 5 um filter and round MPa gauge.
