AirTAC GC400-15 FRL Unit (GC40015ALNW)
The AirTAC AirTAC GC400-15 FRL Unit (GC40015ALNW) is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station.

About the AirTAC GC400-15 FRL Unit (GC40015ALNW)
GC40015ALNW is a genuine AirTAC G-series three-unit F.R.L. set: a separate air filter, pressure regulator and lubricator that together condition compressed air at one station. This 400-size set is ported PT1/2, the filter bowl has an automatic drain, the element is the finer 5 um grade, and the L code makes it the low-pressure type, so the regulated output sits in a reduced setting band; no gauge is fitted as coded (N). Bowls on the 400 size are polycarbonate, inlet pressure is up to 1.0 MPa (145 psi), the medium is compressed air, and the units operate from -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC combination comes in 200, 300, 400 and 600 sizes, with a choice of drain types, 40 um or 5 um elements, gauge options and PT, G (BSPP) or NPT threads. AirTAC publishes flow as characteristic curves rather than a single rating, so we confirm flow and datasheet figures on request before you order.

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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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 (GC40015ALNW)
| 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)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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 (GC40015ALNW) Is Used
Automotive paint spray booth
The 5 um element removes water and fine particulate that would ruin a paint finish, the regulator holds the gun supply steady and the lubricator mists the spray gun's internal seals.
Low-pressure pneumatic clamping station
A fixture clamping station that runs at reduced working pressure gets fine-filtered, regulated and lubricated air from one PT1/2 drop, with the automatic drain keeping the bowl clear unattended.
Screen and pad printing machine
Printing machines with sensitive pneumatic actuation take conditioned air from this set, protecting cylinders and valves from moisture carryover and fine contamination.
Is the AirTAC GC400-15 FRL Unit (GC40015ALNW) the Right Station?
Step between the 200/300/400/600 G-series sizes to match port size and flow demand; the 400 size with its 1/2 inch port sits mid-range for general plant air. Drain choice is automatic (fitted here), manual or the differential-pressure default, so pick automatic where bowls are hard to reach or the line runs unattended. Filter grade is 40 um standard or the 5 um W option; gauges can be added or omitted, and PT is the standard thread with G (BSPP) and NPT as catalogue options. For this low-pressure type, the exact setting range is confirmed on request.
AirTAC publishes flow as curves, not a single rated figure, so ask us to confirm sizing against your application 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 (GC40015ALNW) FAQ
AirTAC publishes flow as characteristic curves rather than a single rated number, so we do not quote a one-line figure. Tell us your application and we will confirm the relevant flow and datasheet figures on request before you order.
L marks the low-pressure type of the G-series regulator section, whose regulated output is limited to a reduced setting band compared with the standard type. The exact setting range for this configuration is confirmed on request.
