AirTAC GC400-15 FRL Unit (GC40015LN)
The AirTAC AirTAC GC400-15 FRL Unit (GC40015LN) 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. It has PT1/2" ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GC400-15 FRL Unit (GC40015LN)
The GC40015LN is a three-piece AirTAC G-series F.R.L. combination: a separate air filter, pressure regulator and lubricator working as one set. Size 400 with PT1/2 (PT thread) ports suits a 1/2 inch compressed-air main, and this version is the low-pressure type with no gauge fitted. The filter element is the standard 40 um grade, the filter bowl drains by differential pressure, and together the three units clean, regulate at a low setting and oil-mist lubricate the air going to your equipment. The filter-section bowl in size 400 is polycarbonate (PC).
This is a genuine AirTAC part. The G-series runs from size 200 to 600, with options that include automatic or manual drains, a 5 um filter element, embedded square or external round gauges, and G (BSPP) or NPT threads as catalogue choices. Maximum working pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. Flow for G-series units is published as curves rather than a single rating, so we confirm figures from the datasheet 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. 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.

| 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". |
| (blank) | Drain: Differential-pressure 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 scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |

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 (GC40015LN) Is Used
Air-knife drying line
Feeds filtered, low-pressure regulated air to air knives that blow water off bottles or cans on a bottling conveyor before labelling, with the lubricator protecting any downstream pneumatics on the same line.
Textile air-jet loom supply
Conditions the compressed air feeding weft-insertion jets on an air-jet weaving loom, where the low-pressure regulator type matches the low working pressure the loom's air circuit runs at.
Packaging conveyor cylinders
Cleans, regulates and lubricates the air supply to carton-flap tuck and pusher cylinders on a packaging conveyor, keeping moisture and particles out of the valve manifold.
Is the AirTAC GC400-15 FRL Unit (GC40015LN) the Right Station?
Choose size 400 (PT1/2) when a 1/2 inch main feeds several cylinders or a larger actuator; the smaller GC200 and GC300 sets cover lighter duty. The L in this code marks the low-pressure type of the regulator section, intended for circuits where the working pressure sits well below normal shop-air settings - send us your set pressure and we will confirm the adjusting range on the datasheet before you order. Drain here is the differential-pressure default; automatic (A) and manual (M) versions exist in the series. Filter grade is the standard 40 um; specify W for 5 um. Thread is PT as standard, with G (BSPP) and NPT (T) as orderable options. A gauge can be added as an embedded square or external round unit if you want a visual setpoint.
Because G-series flow is published as curves and not as a single rated figure, we do not quote a flow number here. Ask us to confirm sizing of the GC40015LN against your application and the AirTAC datasheet 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 (GC40015LN) FAQ
AirTAC publishes G-series flow as performance curves, not as a single rated figure, so we do not quote a flow number on the page. Tell us your air demand and line pressure and we will confirm the sizing from the datasheet on request before you order.
L marks the low-pressure type of the regulator section, used where the downstream working pressure is well below normal shop-air settings. If your circuit regulates around standard pressures, the version without L is the usual choice; we can confirm the right type and its adjusting range from the datasheet on request.
