About the AirTAC GC400-15 FRL Unit (GC40015C1WK)
The GC40015C1WK is a three-unit F.R.L. combination from AirTAC's G series: a separate air filter, pressure regulator and lubricator working together to deliver clean, regulated, oil-mist-lubricated compressed air to downstream equipment. This configuration uses 1/2 in. PT ports in the size 400 body, a differential-pressure drain on the filter bowl, the optional 5 um (W) filter element instead of the standard 40 um, a round external pressure gauge with an MPa scale, and a reverse/check valve fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the regulator adjusts from 0.15-0.9 MPa (20-130 psi) with this drain type; operating temperature is -5 to 70 C (non-freezing). The filter and lubricator bowls are PC (polycarbonate) at size 400.
This is a genuine AirTAC part. The G series is available in sizes 200, 300, 400 and 600, with automatic, manual or differential-pressure drains, 40 um or 5 um filtration, square or round gauges in MPa, psi or bar scales, and G (BSPP) or NPT threads as catalogue options. Flow figures for the series are published as curves rather than a single rating, so ask us and we will confirm the datasheet and sizing 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.
Model Code: AirTAC GC400-15 FRL Unit (GC40015C1WK)
| GC400 | G-series F.R.L. combination, 400 body — sets the port range. |

| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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: GF400-15 filter, GR400-15 regulator and GL400-15 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 GC400-15 FRL Unit (GC40015C1WK) Is Used
CNC machining centre air prep
Feeds the tool-clamp and chip-eject cylinders on a CNC machining centre, where the 5 um element protects precision valves from particulate carryover while the lubricator mists the clamp actuators.
Palletising conveyor diverters
Sits upstream of the diverter and stopper cylinders on a palletising conveyor line, holding a steady regulated pressure while metering oil mist to the actuators.
Bolt-tightening stations
Supplies pneumatic impact wrenches at an engine assembly station; the MPa gauge lets technicians set torque-consistent line pressure and the check valve holds the setting if supply dips.
Is the AirTAC GC400-15 FRL Unit (GC40015C1WK) the Right Station?
Choose size 400 with PT1/2 ports when your line flow and existing pipework call for a 1/2 in. connection; the 200/300/400/600 sizes step port size and flow capacity up or down. The 5 um W element suits downstream valves and cylinders that need finer filtration than the standard 40 um. The differential-pressure drain flushes the bowl automatically as the pressure differential builds - no daily manual draining. The MPa-scale round gauge reads the regulated outlet directly, and the fitted check valve prevents backflow. PT thread is the standard on this model; G (BSPP) and NPT are options to order. Because rated flow is published as curves, not a single number, send us your flow demand and we will confirm sizing against the datasheet before you order.
Quick checklist
- ✓ Body size for your peak flow (PT1/2" 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 GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC GC400-15 FRL Unit (GC40015C1WK) FAQ
AirTAC publishes G-series capacity as flow curves, not a single rated figure, so we do not quote one number here. Tell us your working pressure and air demand and we will confirm the flow from the datasheet on request before you order.
The W code selects the optional 5 um filter grade instead of the standard 40 um, and C1 selects the round external gauge with an MPa scale (psi and bar scales are also available). A differential-pressure drain, PT threads and the fitted reverse/check valve complete this configuration; each can be re-specified if your plant standard differs.
