About the AirTAC GC400-15 FRL Unit (GC40015AC1K)
GC40015AC1K is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled as one 3-piece set. This configuration is size 400 with a PT1/2 (1/2 in) port, automatic drain on the filter bowl, the standard 40 um filter element, a round external pressure gauge reading in MPa, and a reverse (check) valve fitted. The regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) and the set carries a bracket. Medium is compressed air only; maximum working pressure is 1.0 MPa (145 psi), and operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC series is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, in PT (standard), G (BSPP) or NPT threads, with differential-pressure, automatic or manual drains, 40 um or 5 um (W) elements, and the K reverse-valve option. The filter bowl on this 400 size is polycarbonate. Flow is published as curves rather than a single rating; ask us and we will confirm the datasheet and sizing 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.
Model Code: AirTAC GC400-15 FRL Unit (GC40015AC1K)
| GC400 | G-series F.R.L. combination, 400 body — sets the port range. |
|---|---|
| 15 | Port size PT1/2". This body offers 10 = PT3/8", 15 = PT1/2". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |

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 (GC40015AC1K) Is Used
Robotic weld-cell fixtures
Conditions air for weld-fixture clamps that must hold position, with the fitted check valve helping the downstream circuit keep its set state at the F.R.L. outlet.
Case-erector clamp circuit
Feeds the vacuum-block and box-clamp cylinders of a case erector, combining filtration, regulation and lubrication in a single conditioning station.
Press-shop air drop
Serves as the main air-preparation point for a stamping press's pneumatic counterbalance and part-eject circuits, with automatic condensate draining.
Is the AirTAC GC400-15 FRL Unit (GC40015AC1K) the Right Station?
Size 400 with a 1/2 in PT port covers upper-middle flows in the GC range; compare with 300 or 600 sizes for the rest of your line. The K suffix adds a reverse (check) valve to the standard set, which is the only difference from GC40015AC1. The automatic drain suits unattended installations, while manual and differential-pressure drains remain catalogue alternatives. The 40 um element is standard; the 5 um W option is available for finer filtration. The external round MPa gauge is this build's gauge choice, with embedded square gauges (MPa, psi or bar) also offered. PT is the standard thread and G or NPT can be ordered; a bracket is included. 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 (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 (GC40015AC1K) FAQ
Only by the K suffix: GC40015AC1K has a reverse (check) valve fitted, while GC40015AC1 does not. Everything else is the same 400 size, 1/2 in PT port, automatic drain, 40 um element and MPa round gauge. Ask us if you need the datasheet confirmed for either build.
AirTAC publishes GC-series flow as curves rather than a single rating, so no one rated number applies. Tell us your air demand and we will confirm the flow data from the datasheet and check the 400 size and 1/2 in port against your application.
