About the Airtac GC FRL Unit GC400C15C1WK
GC400C15C1WK is an AirTAC GC-series three-unit F.R.L. combination: separate filter, regulator and lubricator units assembled into one set that conditions compressed air end to end. This 400-size version has PT1/2 (PT thread) ports, the W 5 um filter element for finer filtration than the standard 40 um, and the default differential-pressure drain on the PC (polycarbonate) bowls. The K suffix adds a reverse (check) valve, so regulated downstream pressure is retained if the upstream supply is lost, and the regulator carries a round external gauge with MPa scale.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600, with differential-pressure, automatic or manual drains, 40 um or 5 um (W) filtration, round or square gauges in MPa, psi or bar scales, and G (BSPP) or NPT threads as catalogue options. Maximum inlet pressure is 1.0 MPa (145 psi) and working temperature is -5 to 70 C (non-freezing). Flow for the series is published as curves rather than a single rating, so we confirm the datasheet figures for your circuit 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 GC400C15C1WK Is Used
Pick-and-place module air feed
Conditions the air feeding a pick-and-place handling module on an automation cell: the 5 um element protects the directional valves and vacuum generators, while the check valve keeps the gripper circuit pressurised if the plant supply dips mid-cycle.
High-speed carton sealing line
Supplies the flap-tuck and press cylinders of a high-speed case sealer, where stable regulated pressure keeps cycle timing consistent and the check valve prevents the cylinders from drifting back during a momentary supply loss.
Welding fixture clamping circuit
Feeds the pneumatic clamps on a welding fixture table: fine filtration keeps the clamp valves clean, and the check valve holds clamp force on the part if shop air pressure drops while a weld is being made.
Is the Airtac GC FRL Unit GC400C15C1WK the Right Station?
Match the 400 size and PT1/2 port to the air demand of the machine being fed; step to 600 for larger circuits or 300 for smaller ones. With the differential-pressure drain kept here the regulator adjusts from 0.15-0.9 MPa (20-130 psi); a manual-drain variant opens that to 0.05-0.9 MPa (7-130 psi) and an automatic drain suits unattended plants. The W grade (5 um) is the reason to pick this over the standard 40 um set, and the K check valve is the reason to pick it over the plain C1W - both are decodable choices, not extras bolted on later. The C1 round MPa gauge is matched by F-square and psi/bar alternatives, and G or NPT threads can be ordered in place of PT.
AirTAC publishes flow only as curves, not one rated figure, 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 GC400C15C1WK FAQ
AirTAC gives flow for the GC series as performance curves rather than a single rated figure, so no one number is quoted here. Share your operating pressure and air demand with us and we will confirm the datasheet flow figures on request and check whether the 400 size with PT1/2 ports matches your application before you order.
Each suffix answers a different question. W sets the filter element to the 5 um grade instead of the standard 40 um, for finer protection of downstream equipment. K fits a reverse (check) valve in the regulator section so downstream pressure is held if the upstream supply fails. GC400C15C1WK therefore gives fine filtration and pressure retention together; if you only need one of these behaviours, the C1W (5 um, no check valve) or C1K (40 um, check valve) versions are the matching alternatives.
